Comment 363 for bug 621265

@William Thank you.

But i got a bad news, after solving this wifi problem, i installed the propitiatory nvidia driver.
sudo apt-get install nvidia-current
after installing nvidia-current the wifi doesn't connect. It remains in "connecting" state for long time then ask for WEP password again, (same password, saved before). then again "connecting". doesn't connect.
Then i tried adding nvidia.modeset=0 nomodeset to kernel flags. It doesn't help :(

Now if i put my laptop to suspend, then resume after sometime, the wifi connects then. but the speed has dropped again. Not as worst as previous, the speed has decreased :(

I can't realize why it is conflicting with graphics driver :O , but #327 also tells the same things for ati card.

I tried re-compiling iwl3945 module (compat-wireless-2011-03-18). Didn't help.
I'll try compat-wireless-2011-03-29 shortly, will post update then. Any other idea guys ?
