As I am an engineering student, we have computer network lab. In this lab we are taught differnet aspects of computer networking. I had been using Backtrack I was trying very hard to get myself connected to internet.
Then I found the following solution.
At first Open up Terminal and type the following two codes code in separate consoles.
$ /etc/init.d/networking start
$ /etc/init.d/wicd start
Then Click in KMenu > Internet > Wicd Manager
There you’ll see the available networks. Select the network you want to make connection to, If you’ve to use key for authentication then you’ll have to expand the Network name, followed with arrow [bulleted arrow]. Then put your settings and hit ok.
then try to connect. Once you’ve successfully connected. You can surf the internet.
That’s how I connected to internet in backtrack.
Note: Backtrack doesn’t start networking automatically, you’ve to manually start it and when finished you can stop it through command.
$: /etc/init.d/networking stop
Similarly you can stop wicd with command
$:/etc/init.d/wicd stop
Have a wonderful day.
