How to Connect Two Computers with LAN?

These days, we have to connect computers with each other for several reasons. You might want to set up a Local Area connection inside your office using either your desktops or laptops. If you are a student, you can also interconnect more than two computers to play games.

There are numerous solutions to accomplish this task. Generally, this procedure could be divided into two parts, wireless and wired LAN. Here, you will find out how to connect two computers.

For connecting two computers through wired LAN, there must Ethernet card installed on every computer. These days almost all the manufacturers provide pre installed LAN card on their motherboards. In case there is no LAN card installed on your computer, you can get one done easily. These cards are similar to the video cards and you can install them effortlessly on the slot provided in the motherboard.

After installing the LAN cards on your computer, the next step is to connect the LAN cable with the computers. For these kinds of connection, crossover cable is needed.

Click Start > Right Click on My Computer > then Click on Properties

 

Then, from the top menu click on tab named as “Computer Name”

 

Now, click on “Change” button just below the “Network ID” and a new window will pop up.

You will then find a “Computer Name” field. Remember to give a name, which you gave while installing window XP, otherwise it will give a default name. Therefore, it will be better to assign names as system_one, system_two and so on.

There you will find “Member of” field, in which you will find “Workgroup” option. It will have a default name “MSHOME”, you can assign all other subscribers with this group and press “OK”

Your one computer is configured now and you’ll need to repeat the same procedure for the second one. Make it sure to keep the same workgroup with other computers, names can be different.

After configuring both computers, you’ll need to physically connect them.  Plug crossover cable in LAN port of both computers.

Now from the “Start Menu” open “Control Panel” > Click > “Network and Internet Connections”

From the “”Pick a Control Panel icon” > Click > “Network Setup Wizard”

Later, you will find “Welcome to the Network Setup Wizard” page, go to the bottom and right Click > “Next” bottom.

Click Next button again. On doing so, you’ll get the window with three options in it, select the radio button with “This computer connects directly to the internet. The other computers on my network connect to internet through this computer” and Click > Next.

After finishing the wizard from the control panel open “Network and Internet Connection” and Click >Network Connections”

Double click on “Local Area Connections” and Click on “Properties”

Now from the “This connection uses the following items” scroll the bar down and Double Click on > “Internet Protocol (TCP/IP)”

You will observe that the default option is selected as “Obtain an IP address automatically”, check on the “Use the following IP address” option and change it to IP address of your own choice such as 192.168.1.1. Remember to use different IP address for different computers. The next tab will be of “Subnet Mask” and use “255.255.255.0” which will automatically comes after entering IP address. Both computers should have same “subnet mask.” IP configuration window will be as follows.

Then, click on “OK” button.

TeamViewer – Only LAN Connections Possible Problem – How To Solve?

Recently Nishanth posted this query:

Hi,

Teamviewer was working perfectly when i was accessing my desktop remotely on my wifi connection at home.Now that i live far away from home whenever i switch on teamviewer on my laptop to access my home computer it shows a message in green “Only Lan connections possible”.

What exactly is the problem ?

Original link.

If you are using TeamViewer Version 3.6.4606 or above, then a new feature was introduced “Option to allow LAN connections only (turns off Internet access)“. Strong possibility is that you have turned of this option, unknowingly, which is preventing you from connecting to your partner over the internet.

To check if you have accidentally turned this option, go to TeamViewer Advanced Options and check if you have clicked on the “LAN Connections only” checkbox. That should solve your problem.

Software To Sense Packets On LAN And Analyze Network Traffic

Wireshark which was originally known as Ethereal is a network support product which allows you to sense packets on a LAN and use them for the analysis of network traffic. The packet sniffer of Wireshark has to be turned on by the user as a result of which the sniffers start collecting packets on the network and displaying them on the screen.

If your interest is only in specific type of packets, filters can be introduced so that you collect only those packets which meet your criteria. The software is very versatile and is able to capture and analyze packets conforming to over 50000 network protocols. It also supports various physical connections such as 100Base-T, TokenRing, and ATM etc.

In terms of performance and comprehensive features, Wireshark gives a very good competition to the other commercially available products. Being the Open source software, Wireshark can be freely downloaded and used without any licensing instructions. You can even change the code to meet your special requirements provided that the changed code is put back into the Open space.

Continued support of the user community has enriched Wireshark to a great extent with the continuous supply of additional features. The software is more useful for the professional community who is able to understand the subject rather than the average user who may not know much about the packet analyzers.
