Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I just installed 11.04 and wireless doesn't work. It worked just fine with 10.04.2 LTS and 10.10.

The drivers are installed and running (in use) all though, as soon as I plug-out the cable, network is gone and no wireless networks are found in range (normally there are 4-5 networks available in my area so it can't be that there's just none at the moment);

Do you have any suggestions?

This helped me fix the wireless on my dell d630, thanks! –  mikelong May 23 '11 at 9:50

I had the same problem, but fixed .. by enabling wireless :D:D

in ubuntu 10.04 the hardware button did not work - here it works. On your dell there should be a button on the laptop to enable/disable wifi - with Ubuntu 11.04 - it actually fully functions - try clicking it :)

helped for me with MSI laptop :)

Hi Vytautas, my WiFi is turned on, as I never touch this button, but I tried to on/off it, no effects. :/ –  Daniel Apr 30 '11 at 10:38
