Installing iwlwifi was one of the first things that I did. I obtained the package from http://packages.debian.org/wheezy/al...lwifi/download Installing the package does not help bringing up the interface.

While I am using whezzy, I cannot use internet at all. The reason is that only wireless is available. But how can I use the wireless when my wireless interface does not exist?

OK the wireless interface exists, but not for Wheezy. Now that I am writing this, I am using Squeeze.

Can you connect by ethernet just for testing purposes

Thanks to all who contributed to this thread.
The problem is now almost solved.
The problem was that after installing iwlwifi, I could not take advantage of rebooting
because I was using a live DVD.
Apparently, after installing iwlwifi, I needed to reboot. But rebooting with a live DVD would not make much sense.
So, I decided to install debian 7.
After installing iwlwifi on the installed system, I faced the same problems. But rebooting fixed the issue.
Now wireless is working.

Does anyone have any idea as to how the solution could extend to a live environment?
Mind you, in a live environment, logging out and logging in did not work.

LOL Yeah live cds are not fully functional due to non-persistent data

The only way to make it work in a live environment would be to modify the livecd (non trivial)
