Ubuntu 10.04 TLS wireless issues

Hardware: Dell D830 Latitude

I am a Linux newbie. I installed Ubuntu 10.04 using wubi installer in my Windows 7 laptop.

When I installled and ran it for the first time it asked me for the wep key I provided it , connected and was able to browsed Internet just fine. I installed Chromum browser. I shut it down and today I cannot access wireless and the "Enable wireless" option is greyed out.

On the Windows 7 install the wireless is just fine

Any ideas how to solve it?

Run the following command in the terminal:

sudo rfkill list

Open in new window

Do you get any "Hard blocked: yes" or "Soft blocked: yes" entries?
Then this may indeed be a case where Ubuntu does not correctly interpret the WLAN killswitches, so play around with the keyboard 'Fn + Enable/Disable Wlan' key, and check the laptop manual for a hardware switch that you may click. (It does not matter that WLAN works under Windows; Windows uses specific drivers as supplied by hardware manufacturers, Linux has to learn to support all hardware features by itself, so an occasional 'misunderstanding' of a brand specific button can occur.)

You may also want to try:

sudo rfkill unblock all

Open in new window

Yet another method that is reported to have worked for some Dell laptops is this command:

sudo rmmod -f dell-laptop

Open in new window

Thanka Tobias. Turning the switch off and rebooting did the trick.
