Networking Notebooks

Accurate Africa · 07-05-2009, 01:38 PM

Is it possible to interconnect two notebooks using a crossover cable (with RJ-45s at each end) and be able to access the internet line that is connected to one of them without using a modem? I have succeeded in linking them via wireless but cannot connect to the internet on both with one line. Please advise.

It is indeed. It's been a while since I did anything like this as ethernet switches are so cheap, but IIRC, I believe that the process goes something like this:

On the laptop with the internet connection select your internet connection.
Right click on it and select properties.
The connection properties dialog box should be appear.
Select the Advanced or Sharing tab (Can't remember which).
Check Allow other network users to connect through this computers internet connection.
Ensure that the two options below are unchecked.
Click the OK button. This will give you a message stating that IP address of present working PC will be set to 192.168.0.1.
Click OK (If you assigned this address to any other computer then change it to a different IP address otherwise it will generate an IP addressing conflict error).
Now a hand icon should appear below the connection, indicating that it has been shared.
Connect the crossover cable between the two laptops.
Go to the other laptop, right click on your LAN connection and select properties.
In the LAN properties dialog box select Internet Protocol (TCP/IP).
Click the properties button.
The Internet Protocol (TCP/IP) properties dialog should appear.
Assign an IP address of 192.168.0.2 or higher.
Assign the Default Gateway and DNS Server IP as 192.168.0.1.

NB: You'll need to make sure that your internet connection on the first laptop is on an IP range other than 192.168.0.0 /24. For instance: 192.168.1.0 255.255.255.0. This shouldn't be an issue if the first laptop has a dial-up connection though.

If this doesn't work let me know.

Regards,
