For IT lovers and Tech geeks, It’s time to Setup a Penetration Testing Lab to learn Information Security and testing some hacking tips for protecting our network or home computers from being hacked. This Lab we are going to create is not only for Hacking and Penetration Testing. It’s the lab which is necessary for all computer science students and technology geeks.

A Lab within a computer reduce electricity usage and has many more benefits. Even you can create it within your personal Laptop. If it would be on a laptop, it is portable and you can carry everywhere with yourself. The time is gone when the hardware of a computer was weak and just could run an operating system with a few software. But nowadays each computer at least has a CPU i3 or higher with 4 GB RAM or higher. So you can run multiple virtual operating systems (OS) separately at the same time.

Virtualization Tools To Set Up A Penetration Testing Lab

There are many Virtualization software for this purpose and all of them are easy to install and using a virtualization environment. Hyper-v,  a free and built-in hypervisor software on Windows 8 higher. It’s the best and I like it too much, but for enterprise network and working with Microsoft software products. Like SQL Server, Windows Server, System Center,  and others.

When we are using for multi-vendor products, Linux, Windows, Mac OS, Chrome OS, Router IOS, and Web Server and web Apps, we must install and test them on Lab that can support all of them. So from basic hacking a standalone PC to Wireless hacking and even web app penetration testing to enterprise network penetration testing I suggest to create your lab with VMWare.

VMWare workstation is the appropriate tool for setting up your penetration testing lab and networking training lab. Unfortunately, it is not free like Hyper-V. But you can use VMWare player for free which is not more flexible and doesn’t have the same functions as a workstation.

So good, you completely understand which Virtualization software is preferable and flexible for Learning Penetration Testing and Hacking. Now try to create your lab. First of all download all software you need for testing. Windows Server, Windows Client, Linux Operating system, and Web Application penetrating testing.

Install VMware as Virtual Host Server

Now go to VMware website and download the VMware workstation. Download the Windows edition if you are using Windows. It has for Linux and Mac OS also.  When the download complete successfully, simply install it like simple software installation and create a new virtual machine according to this step by step article ” How to Create A Virtual Machine in VMWare?“.

Note: Your system must meet the virtualization requirement. It must support virtualization technology (VT) and enabled before installing any virtualization software. You can enable it through your system BIOS where you can find other settings also.

To install Kali Linux on VMWare read the article “How to Install Dual Boot Windows and Kali Linux?“. In the next step, I will show you How to configure VMWare for Penetration Testing Lab.

Deleting a WiFi profile in Windows 10 has a long process. In this post, we will show you an easy way to forget Windows 10 WiFi network profile with command. Try to use the command line for managing Windows 10 to get expert on Windows PowerShell and command-line interface on Windows environment.

Delete WiFi Network Profile

When you join WiFi networks with your Laptop, the WiFi profile has saved on your computer. In a case for joining the WiFi network with the same name or changed WiFi password, you need to delete the current WiFi profile. Let’s do it first with the command line and finally with GUI.

To forget a WiFi Network on Windows 10 using GUI:

1. Click the WiFi icon on the taskbar on the right side of the desktop screen.
2. Click Network Settings.
3. Then click Manage known networks.
4. On the Manage known networks, select a WiFi network profile and click Forget.

The screenshot shows the process you rich the Wireless network settings and forget Windows 10 saved WiFi network profile.

Note: You can find the Wireless network settings on Windows 10 by typing “WiFi” on Windows 10 search box. The Change Wi-Fi settings are the exact Wifi settings we need.

I don’t know why Microsoft removed the ability to delete Wi-Fi networks from the network list if the network isn’t in range. Manage Wireless Networks is also gone from the control panel. If you want to better manage Wi-Fi networks in Windows 10, you’ll need to head to the command line.

As the screenshot above shows, Windows 10 does have a “Forget this network” option, but it doesn’t appear in the network is not in range. To delete old profiles, you’ll need to use the netsh command-line utility.

To delete a Wifi network profile in Windows 10 press Windows+R keyboard button then types PowerShell to open Windows 10 PowerShell. You can use CMD as well.

1. To See Stored Wireless Profiles, type:

1. Type “netsh WLAN show profiles” and press enter.

You see the two saved Wireless network profiles on my computer. It will show a list of saved profiles of your connected WLAN devices. Then you’ll need to know the profile name that you want to change.

2. To See the Stored Key (WPA/WEP/etc.) of a Specific Profile:

1. Just type “netsh WLAN show profiles name=”OVICT” key=clear” and press enter.

That’s good; you’ll find the critical content under security settings. The next step is to delete a WiFi network on Windows 10 with the command line.

3. To Delete a WiFi network on Windows 10:

1. Just type “netsh WLAN delete profile name=OVICT” then press enter.

Perfect, the saved WiFi network profile removed successfully. Now, try to check once again with “netsh WLAN show profiles” command to see if the Wifi network has removed.

When a system DNS works for a long time, it saves many records that cause DNS works slowly or not working correctly. To flush DNS cache, you need to clear DNS records from your system. You can do it with the command line in command prompt and Windows Powershell and Terminal on macOS systems.

The flush DNS command is the tool you need to clear and flush DNS cache. Just open the command line interface and dump the correct DNS cache then remove it.

The Domain Name System (DNS) is a hierarchical decentralized naming system for computers, services, or other resources connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates more readily memorized domain names to the numerical IP addresses needed for locating and identifying computer services and devices with the underlying network protocols.

Clear and Flush DNS Cache with the command line:

1. Open a command-line interface
2. Display DNS Records
3. Flush DNS Cache
4. Check DNS Records

To flush DNS cache just follow the step by step guide. It works the same on all Windows operating systems, but different on various macOS and Linux distributions.

How to View DNS Cache

To view DNS cache on Windows systems, just type “ipconfig /displaydns” in command prompt.

1. Press Windows+R to open the Run.
2. Type “cmd” and press enter to open the command prompt.
3. Now type “ipconfig /displaydns” to view DNS cache and records.

The ipconfig /displaydns result is like this.

There are too many DNS records on my system. But this is just an example of DNS cache in Windows system.

Flush DNS Cache in Windows 10

To clear Windows 10 DNS cache and records, type the “ipconfig /flushdns” command in command prompt or PowerShell.

PS C:\Users\Shais> ipconfig /flushdns
Windows IP Configuration
Successfully flushed the DNS Resolver Cache.

That’s good, the DNS cache removed successfully. This command works the same on all Windows client and Windows server machines.

Check DNS Records

Now if you check again you can not find any DNS records.

PS C:\Users\Shais> ipconfig /displaydns
Windows IP Configuration
Could not display the DNS Resolver Cache.

Yes, the system can not display the DNS records. Because there is no DNS record cached yet.

Flush DNS Cache on macOS

Flushing the DNS in Mac OS X is an easy process, but the steps taken will depend on which version of OS X you are running. For the different version of macOS operating system use the following command to clear and flush DNS cache.

macOS Sierra, OS X El Capitan, Mac OS X Yosemite, Mac OS X Mavericks, Mac OS X Mountain Lion, Mac OS X Mountain Lion, and Mac OS X Lion.

If you are running Mac OS X 10.11, you need to follow the below steps:

1. Open up the command terminal.
2. Run the command sudo killall -HUP mDNSResponder

Mac OS X Snow Leopard.

If you are running Mac OS X 10.6, you need to follow the below steps:

1. Open up a command terminal.
2. Run the command sudo dscacheutil -flushcache

Mac OS X Leopard and below.

If you are running Mac OS X 10.5.1 or below, you need to follow the below steps:

1. Open a command terminal.
2. Run the command sudo lookupd -flushcache

Flush DNS Cache on Linux

If you are running the nscd Name Service Cache Daemon and wish to flush your DNS cache, then you will need to do the following.

1. Open up a command terminal (either as root or run step 2 with sudo).
2. Run the command /etc/init.d/nscd restart
3. Now, you just have to restart the NSCD. To do, type the following command

The 4G WAN features for small business and home network. 4G is becoming an increasingly popular connectivity choice for organisations of all sizes. In a world where business agility is the only way to make sure you’re at the front of the queue when opportunities arise – being able to set up a wide area network (WAN) at short notice gives you the responsiveness you need.

When time is of the essence, a managed service provider can have your site connected in just a couple of days – and while that might give them superhero status from your company’s point of view – it’s a combination of experience, preparation and the right equipment that means they can act so quickly.

We’ll have a look at what’s found in a 4G ‘Rapid Site Deployment’ box – explain a little about how each element works – and what it could mean to your business.

What is 4G WAN Features?

Before exploring the technology in detail – it’s useful to know what 4G WAN is.

Essentially, 4G WAN is the use of SIM cards and cellular data to create a circuit that connects a business site to the other sites on its WAN.  So, rather than the site being connected to the WAN via a fixed line such as DSL, EFM or a fibre Ethernet circuit,  it’s connected wirelessly.  Of course, it should go without saying that when using 4G technology to connect business sites, the performance and reliability required is far higher than when using 4G for an individual.  Also, 4G can be used to connect a site either to the WAN or the internet.

The benefits of 4G WAN

The flexible nature of working without cables means 4G offers some significant benefits to an organisation – the most commonly sought are:

• Mobile deployment – With engineers, service and sales personnel in the field, 4G WAN can connect company vehicles to the WAN or internet as easily as permanent locations.
• Temporary business locations – If you’ve got temporary business premises, shows, expos, sites or client premises from which you work – 4G WAN gives you quick and secure enterprise level access to your network.
• Waiting for a circuit? – Installation times for business ethernet and fibre circuits are notoriously long and often experience significant unexpected delays. 4G WAN can be a highspeed stop-gap until your circuit is in place.
• Backup network – When disaster strikes a 4G Rapid Site Deployment service can have your business operating again at a fraction of the time it would take to remedy significant network problems.

What’s involved?

A walk-through video of a 4G Rapid Site Deployment kit can be viewed here – but as an overview, this is what you can expect to be included:

Case

It might seem a detail too far to focus on the case the 4G WAN kit comes boxed in – but in a lot of instances, it’s an important part of the kit.

4G WAN solutions are used by some industries that require strong solutions – there’s every chance a kit could find itself on a boat or helicopter heading for a remote drilling, construction or exploration site – just as it could end up in city centre office. A rapid site deployment solution is equipped for any environment.

VPN 4G Router

At the heart of the kit is a VPN 4G Router.

This type of router will be preconfigured by a managed provider who will establish and understand your requirements before the kit reaches you. The cellular connection is created with the addition of SIMs to the router. Most routers will have the capacity to hold some SIMs – anywhere between 2 and 20+.

These SIMs are provided by two or more cellular network providers. Should there be any problem with one network, connectivity will not be lost, meaning your network stays up no matter what. SIMs can be configured (and re-configured) according to the coverage available and the capacity required.

The data connection that’s established by using SIMs is usually combined or ‘bonded’ by the router software to create one fast and robust connection.

Aerials

The aerial needed for your installation will depend on some variables. Generally speaking, a 4G WAN solution will come with indoor aerials – in most instances, the signal is strong enough for 4G to be picked up by these aerials – and there will be two (appropriately spaced) as is the norm for 4G connectivity.

However – as we’ve previously noted, 4G WAN features boxes will often find themselves in remote and inhospitable areas, so other options are also frequently provided:

• Exterior aerials: In many instances – rigs, construction sites, mining and so forth – there will be objects that shield the router from establishing a real connection. In cases like this an exterior aerial will be required.
• Directional high gain aerials: In instances where a 4G box is deployed a long way from cell masts, a larger ‘high gain’ aerial can be mounted to an external wall or on poles before being correctly orientated for maximum effectiveness.

Additional services

While the components listed are all that is physically required to put the network into place – there’s also a lot of configuration and support that needs to happen behind the scenes. The managed network provider who’s supplying the service will also:

• Provide and configure the SIMs from appropriate cellular networks to ensure you get the performance required.
• Install the required switches and access points.
• Monitor the performance of your WAN (ideally 24/7).
• Monitor the cellular usage and support you to manage that – making adjustments on your behalf if required.
• Establish a plan for migrating your network to a more permanent solution if required.

4G rapid site deployment vs. circuit installation

It’s when you compare the setup times of the different network connection options that you can see why so many organisations opt for 4G WAN. Openreach currently quotes around 60 days to install a fibre Ethernet connection – and in a lot of instances, this timescale will see significant delays when construction work is required for a line to reach your premises.

An experienced managed service provider could have your 4G WAN features solution up and run within 2-3 days. They’ll begin with a cellular site survey – this will help establish which mobile carrier(s) can provide the best cellular coverage and how many SIMs you’d require meeting your business needs.

If being responsive is the key to your company winning or keeping customers, a 4G WAN deployment managed by the right company could be the key to success.

We have many articles related to file sharing between Linux and Windows 10. Because of various Linux distributions, we receive some new request about file sharing between Linux and Windows. In this article we just collection all informative articles about file sharing between Linux and Windows systems.

If you use different Linux distribution, just apply the one that works perfectly or comment us for solving file sharing problems between Linux and Windows 10.

File sharing is easy but keep in mind that secure file sharing is a bit different. You must know something about computer security and safe file sharing system. Sometimes you just share a file on the network and accessing it over the network computers. Do you know the other can access your file if you did not configure the file sharing permission correctly?

Sharing File Between Linux and Windows 10

To share files and folders between two different operating system, just know the file sharing options of both operating systems. Before starting secure file sharing, make sure your computers are on the same network and connected with each other. The “ping” command will help you can ping between two systems using the command line.

To ping, another system just types “ping IP address another system.”

ping 192.168.10.11

Yes, the result of successful ping should be like the above screenshot. The result “request timeout” and “Destination host unreachable.” means that the system is not accessible or system firewall security blocked the ping echo.

I recommend you to read the article about networking Linux and Windows system. This article completely cover to network the Linux with Windows system.

You can reset Windows 10 IP address with these three methods, using network connections settings, command prompt, and PowerShell. The easiest option to reset Windows 10 IP address with command prompt (CMD). If your system obtains its IP address automatically from a DHCP server, the “ipconfig” command can refresh your system IP address. The refreshing IP address process releases the old IP address and requests a new IP address from the DHCP server.

The other methods for changing Windows 10 IP address is GUI from network connections settings and using Windows PowerShell. Let’s do it with the easy one inside command prompt with ipconfig command.

Reset Windows 10 IP Address

To reset Windows 10 IP address, just open the command prompt or PowerShell interface and do it with the following “ipconfig” commands.

Resetting Windows IP address needs:

1. Press Windows+R to open the Run.
2. Type “cmd” and press enter.
3. To display the current IP address type “ipconfig.”
4. Check the output results of “ipconfig” commands.

1. Press Windows and type “PowerShell” and open the Windows PowerShell. Now type “ipconfig.” The IP config command shows the current system IP address. Here my computer IP address is 200.100.10.2 with the subnet mask of 255.255.255.0 and default gateway of 200.100.10.1.

2. To reset your system, IP address just types “ipconfig /release” and press enter. The /release option of ipconfig command will remove the current IP address. When the “ipconfig /release” command process has finished, type “ipconfig /renew” to obtains a new IP address from DHCP server.

Yes, the output result of ipconfig /release shows that the current IP address removed. Now the system doesn’t have an IP address, and it is ready to obtain a new IP address from DHCP server.

3. To get a fresh new IP address, just type “ipconfig /renew.” The /renew option of ipconfig command request a fresh new IP address from the DHCP server.

That’s good. The output result’s of ipconfig /renew shows that the system obtains a new IP address from the DHCP server.

IPConfig Command Structure:

The ipconfig command has many options that help you quickly execute and get a clean result. To learn more about other options of ipconfig command, type “ipconfig /?”. It shows the help of ipconfig. See the output result of “ipconfig /?” command in the below text box.

USAGE:
    ipconfig [/allcompartments] [/? | /all | 
                                 /renew [adapter] | /release [adapter] |
                                 /renew6 [adapter] | /release6 [adapter] |
                                 /flushdns | /displaydns | /registerdns |
                                 /showclassid adapter |
                                 /setclassid adapter [classid] |
                                 /showclassid6 adapter |
                                 /setclassid6 adapter [classid] ]

       /flushdns        Purges the DNS Resolver cache.
       /registerdns     Refreshes all DHCP leases and re-registers DNS names
       /displaydns      Display the contents of the DNS Resolver Cache.
       /showclassid     Displays all the dhcp class IDs allowed for adapter.
       /setclassid      Modifies the dhcp class id.  
       /showclassid6    Displays all the IPv6 DHCP class IDs allowed for adapter.
       /setclassid6     Modifies the IPv6 DHCP class id.
Examples:
    > ipconfig                       ... Show information
    > ipconfig /all                  ... Show detailed information
    > ipconfig /renew                ... renew all adapters
    > ipconfig /renew EL*            ... renew any connection that has its 
                                         name starting with EL
    > ipconfig /release *Con*        ... release all matching connections,
                                         eg. "Wired Ethernet Connection 1" or
                                             "Wired Ethernet Connection 2"
    > ipconfig /allcompartments      ... Show information about all 
                                         compartments
    > ipconfig /allcompartments /all ... Show detailed information about all
                                         compartments

That’s the help you can always access from the command prompt or PowerShell.

The post How to Reset Windows 10 IP Address Correctly? appeared first on TECHNIG.

Configuring IP address in a Windows with CMD performed using netsh command line utility. The network shell (netsh) is a set of commands that help you configure any Windows operating system IP address, Network Interfaces, and Windows Firewall. The usage of the command line is for pro level Windows users. Those who are playing the network infrastructure configuration. But using the command line as normal Windows user indicate your expertise to Windows environment. If you are new to Windows command line, this article “configure IP address with command prompt in Windows 10” will help you begin using command line interface.

Configuring Windows IPv4 Networking with Netsh or Network Shell. Netsh is a command-line utility included in Microsoft’s Windows NT line of operating systems beginning with Windows 2000. It allows local or remote configuration of network devices such as the NICs.

Configure IP Address with Command Prompt in Windows 10

Before setting IP address with cmd in Windows 10, you need to know how to find your IP address on Windows 10. So before everything, you must know the network IP address configuration on your system.

Let’s learn the process of IP configuration step by step. I am going to explain it with an easy pictorial guide. If you don’t understand some part, just kindly comment us and ask your questions.

The process of Changing Windows 10 IP Address with Command Prompt: 

1. Find your IP address in Windows 10.
2. View network interfaces card.
3. Change IP address on Windows 10.
4. Change DNS IP address with the command line.
5. Reset IP address with Command Prompt.

How to Find your IP Address on Windows 10?

There are many options for finding IP address on Windows 10. The easy one is “ipconfig” command. To find your IP address on Windows 10, just type “ipconfig” in command prompt. To do this process:

1. Press Windows+R keys to open the Run.
2. Type “cmd” in the run and press enter.
3. Now type “ipconfig” to show the IP address.

The “ipconfig” command shows everything about your computer network interfaces. You might have many physical or virtual network interface card.

Here, I just have one network interface on my Windows 10 computer. The result of ipconfig command shows that the IP 169.254.29.130 with the mask of 255.255.255.0 is my current Windows IP address.

This is a class C “autoconfiguration IPv4”. When your system doesn’t find any DHCP Server or manual IP address, it obtains auto IP address. So let’s change it.

How to Change IP Address with Command Prompt?

For change IP address, open command prompt or PowerShell. Both works the same and you can run all command prompt commends on Powershell as well. Ok, run cmd or Powershell as administrator. Netsh work in both command prompt and Powershell. I’m using Windows Powershell to change IP address on Windows 10 completely. Becuase the user interface and color’s of Powershell is better than Command prompt.

1. Type “Powershell” in Windows 10 search box to run Windows Powershell.
2. You need to run Powershell as administrator. Just press Windows+Shift the press enter to run Powershell as administrator. Or right-click the Powershell and click Run as administrator.

To find the network interface with the command line, type the following command on Powershell.

Netsh interface ipv4 show interface

The result shows two network interfaces. The Loopback and the Ethernet. The Loopback is Windows builtin network loopback interface, but our pointed network interface is the ethernet.

To find your IP address in Windows 10 with netsh command, just type the following command.

netsh interface ipv4 show config

It displays all the network interface configuration. The output result is clear and better than output result of “ipconfig” command on Command prompt. So to find an exact information of the network interface, just add the index ID of the network interface at the end of the command.

netsh interface ipv4 show config 2

That’s good. Let’s configure and change Windows 10 IP address with the command line. The command is bit long but easy to understand. No need to remember, just try to understand the netsh command structure.

To change the IP address of the “Ethernet0” network interface, type the following command.

netsh interface ipv4 set address name=2 static 200.100.10.5 mask=255.255.255.0 gateway=200.100.10.1

Once the command executed successfully, check the result with “netsh interface ipv4 show config 2” command. Yes, the output result shows the exact IP address has set on the “Ethernet0” network interface. Now the Windows IP address is 200.100.10.5 with the mask of 255.255.255.0 and default gateway is 200.100.10.1.

Note: You can’t change the default gateway separately with the following command. It will remove the IP address and just set the default gateway address.

netsh interface ipv4 set address name=2 gateway= (Gateway IP Address)

That’s good and enough for IP address configuration in Windows 10 with the command line. Let’s change DNS IP address from the command line.

How to Change DNS IP address from Command Prompt?

DNS IP address is the unique address in the network that resolves computer name to IP address and IP address to the computer name. In the network, finding a computer with a name is easy than 32-bit IPv4 address. To set or change the DNS IP address, just simply do it with the following command.

netsh interface ipv4 set dns name=2 static 200.100.10.30

You might see some error on a simple local network, because of not having a DNS server. When you don’t have a DNS server, it’s not necessary to set DNS IP address on your computer.

Finally, recheck the result with “netsh interface ipv4 show config 2” command. The output netsh command should be displayed with DNS IP address.

Final World

Configure IP address with command prompt in Windows has tow benefits. The first benefit of working with Windows command line helps get you improve your skills in Windows environment. The second benefit is command line is faster than GUI. If you work with the command line, you will understand the power of command line.

The Windows command line interface has improved a lot in Windows 10. Now you can find some Linux commands that run in Windows 10 and works the same on Linux. Finally, hope you learn how to configure IP address with Command Prompt in Windows operating systems. If you don’t understand, please ask us about how to configure IP address with command prompt in Windows 10?

Configure Static Routing is the routing that network administrator configures the network routers manually, instead of using routing protocols RIP, OSPF, etc. which utilized in the dynamic routing. The benefits of static routing are minimum bandwidth usage, no overhead on router CPU and much more and perfect for a small network with a few routers. But it is not without cons. It ‘s hard to configure all routers manually in the vast network and troubleshooting is always harder than configuration.

As a network administrator or student of CCNA, you must know the configuration of static routing. It helps you understand the process and functions of routing in the network apparently.

Configure Static Routing Using Cisco Packet Tracer

To perform this task, you must create a lab and configure the basic IP addressing for all PCs and Routers or download my CCNA Lab – Static Route with Cisco packet tracer. CCNA Lab – Static Route – no Configure.

I have configured the Static Route the same as the screenshot, and it is not yet configured routing. You must configure it with below step by step Static Routing guide.

Static Routing command syntax: Ip route [destination network address] [mask] [next hop address or interface name]

1. In the R1 type the following commands to introduce two LANs 192.168.10.0/24 and 192.168.30.0/24 for Router 1.

R1(config)#ip route 192.168.30.0 255.255.255.0 10.10.20.2 150
R1(config)#ip route 192.168.10.0 255.255.255.0 10.10.10.2 150

2. Router2: Add three networks for router 2 and be sure that do not configure it with wrong IP address.

R2(config)#ip route 192.168.10.0 255.255.255.0 10.10.10.1 150
R2(config)#ip route 10.10.10.0 255.255.255.0 10.10.20.1 150
R2(config)#ip route 192.168.20.0 255.255.255.0 10.10.20.1 150

3. Router3: Do the same as router 2 but with different destination and exit interface address.

R3(config)#ip route 192.168.30.0 255.255.255.0 10.10.20.1 150
R3(config)#ip route 10.10.20.0 255.255.255.0 10.10.10.1 150
R3(config)#ip route 192.168.20.0 255.255.255.0 10.10.10.1 150

So it’s easy and not too much difficulty. If you want to accomplish this task, firstly you must try to understand the concept of routing and then try to configure it.

You can download the complete Static Routing Lab from the link below and look at the routing configuration with ‘show ip route or show run‘ commands.  CCNA Lab – Static Route. If you have any question, please feel free to ask us.

WiFi internet connection is the most common and popular type of home networks nowadays. But it also has one major drawback that, due to being wireless, it can easily breakdown. Troubleshooting this type of internet connection can a nightmare for any person. Luckily for you, here are some of the most important steps you can do in order to troubleshoot your wifi connection.

Are you able to Ping from your WiFi Internet Connection?

The first thing you wanna make sure that whether your WiFi internet connection is actually going wrong or not?

Related article: How to find WiFi Password in Windows 10? 

For this thing you can do a ping test  There are many small utility Softwares that can help you go through it but you can do it on own using cmd on your PC. All you need to do is open up cmd into your PC, then type Ping [any website]. An example of this command can be:

Ping google.com.

After you type this command your device will send a small amount of data packets to the target site and if you see a “reply”, then your internet connection is perfect.

But if you’re not getting any reply even after pinging multiple times, there is a problem with your network.

Have you checked your network setup

It’s important to check your whether there’s an external fault in your network setup or not. More: 5 Steps To Secure Your Home Wireless Network.

First of all, you need to check your router. If there’s no LED light showing any status, it means your router is either disconnected or not in power. Make sure that the power cord is connected to the router and the power switch is on at that moment.

Another thing you should check is the internet cable going into your router. Verify that that cable is properly connected to your router and is in good shape e.g: not broken, chewed up etc.

If nothing good happens, considering rebooting your router.

Do You have an updated firmware?

Outdated router firmware is potential hacker’s heaven. It’s because a lot of times an outdated firmware contains a lot of bugs, potential vulnerabilities etc. That’s why it’s better to check for an outdated version of your router’s firmware from time to time.

Is Your PC Healthy?

Apart from slowing your overall PC,  viruses/malware can also slow down your internet connection. This is the reason why you should install a good antivirus to clean up your PC.

Is Your Router Old?

Many people don’t realize that an old router can slow down your network. It’s because old routers weren’t designed t handle these many devices.

Last Resort: Dial Up Your ISP

If all of this didn’t help you troubleshoot your wifi network, then there’s only one last solution. Call your ISP and let them know your problem.

Configure DHCP on Cisco Router. Last week we published a topic about installation and configuration of DHCP Server in Windows Server 2012 R2. We have introduced the DHCP Server “Install and Configure DHCP Server on Windows Server 2012 R2” and told the necessary services and network protocols requirement if you don’t know the basic of DHCP Server? you must read the article first.

Create and Configure a CCNA Lab within Cisco Packet Tracer.

Download the DHCP configuration in Cisco router lab of packet tracer from the end of this post or try to create your own network lab with two routers and their LAN networks and then configure it with the following step by step guide.

Configure the Router 1 with below IP address and initial configuration. I assume you know and understand the basic router and Switch configuration clearly. So no need to explain the functions of the basic router and switch commands line.

Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#hostname R1
R1(config)#interface serial 0/0/0
R1(config-if)#ip address 10.10.10.1 255.255.255.252
R1(config-if)#no shutdown

R1(config-if)#clock rate 64000
R1(config-if)#

For Router 2, configure the same interface serial 0/0/0 and FastEthernet 0/0 with the following commands.

Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname R2
R2(config)#interface serial 0/0/0
R2(config-if)#ip address 10.10.10.2 255.255.255.252
R2(config-if)#no shutdown

R2(config-if)#

R2(config)#interface fastEthernet 0/0
R2(config-if)#ip address 192.168.10.1 255.255.255.0
R2(config-if)#no shutdown

Configure DHCP on Cisco Router Using Packet Tracer

Let’s configure Router 2 as DHCP Server and set the clients to get their IP address from DHCP Server in Cisco Router.

In the R2 while you are in the config mode, type the command ‘IP DHCP excluded-address 192.168.10.1 192.168.10.20‘ and then press enter. This command ‘ip dhcp excluded-address’ will create an exclusive range of IP addresses which reserved for Network Servers and DHCP Server will not assign them to clients.

The ‘ip dhcp pool‘ command creates a pool for a network. You can create many pools on a router for all Local area network that connected to the router.

R2>enable
R2#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#ip dhcp excluded-address 192.168.10.1 192.168.10.20
R2(config)#ip dhcp pool Technig_Clients
R2(dhcp-config)#
R2(dhcp-config)#network 192.168.10.0 255.255.255.0
R2(dhcp-config)#default-router 192.168.10.1
R2(dhcp-config)#dns-server 192.168.10.100
R2(dhcp-config)#

Now go to client setting and set the IP Configuration to DHCP and see the client get a new IP address from DHCP Server.

So that’s it, configure DHCP on Cisco router within a minute! Simple and easy.

DHCP Relay on Cisco Router

Remember some DHCP options (DHCP Relay Agent) when you need to provide IP addresses from a DCHP server to clients that are outside of your network or are not in the same Local Area Network. You must use the ‘ip helper-address‘ to forward the DHCP client requests to the remote host.

Configure the R1 to relay the DHCP client request. It does not work without routing. So configure Routers with static or dynamic routing. Here I’m testing with RIP.

R1>enable
R1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#interface fastEthernet 0/0
R1(config-if)#ip helper-address 10.10.10.2
R1(config-if)#exit

R1(config)#router rip
R1(config-router)#network 10.10.10.0
R1(config-router)#network 192.168.30.0
R1(config-router)#exit

Go to the client IP configuration setting and see the forwarded request by DHCP Server.

Hope you learn the configuration of the DHCP Server on the Cisco Router and Download the DHCP on Cisco Router Packet Tracer.
