Re: Enable Wireless - unchecked and greyed out
First-timer asking for help. ^^'
I have a strange problem with the wireless too, where the Enable Wireless option is unchecked and grayed out. (Dell Inspiron n5010)
When I run 'rfkill list' and 'sudo lshw -C network' one way I get this:
--

Soft blocked: no
Hard blocked: no
1: dell-bluetooth: Bluetooth
Soft blocked: no

However, when I press the wireless key and run the two again, it changes to this:

... and that goes back and forth.
Any advice?
Re: Enable Wireless - unchecked and greyed out
Please run:
Code:
sudo rmmod -f dell-laptop
Repeat the tests. If the wireless is working now, do:
Code:
sudo su
echo "blacklist dell-laptop" >> /etc/modprobe.d/blacklist.conf
exit
Then the errant module will be permanently blacklisted.
Re: Enable Wireless - unchecked and greyed out
I followed your instructions and it worked, my wireless is fine.
But can you, by any chance, tell me what 'sudo rmmod -f dell-laptop' does, and why it needed to be handled as it did ('echo "blacklist dell-laptop" >> /etc/modprobe.d/blacklist.conf')?
I'm trying to learn some stuff here at the same time, and hopefully, this will help me help others. ^^
Re: Enable Wireless - unchecked and greyed out
Ive got the same problem on an Acer Aspire One but neither the 'rfkill unblock all' nor the 'sudo rmmod -f sn-netbook' have any effect.
Am I missing something here? Whats the correct name of the module for Acer Aspire Ones?

The first command temporarily removed the dell-laptop module. It would have returned at the next boot. The second made it permanent by not allowing it to load at boot-time (blacklisted it).
From an earlier Dr Chili post (must be coffee-ing!)

dell-laptop is supposed to enable some functions that are unique to Dell. As you can see, it doesn't work well. I suspect that it conflicts with another similar module, dell-wmi. If you notice that other functions now don't work correctly, obviously reverse the removal.

dell-laptop is now blacklisted and will not reload on boot, unless, of course, you edit /etc/modprobe.d/blacklist.conf to remove the blacklist line.

Would you please start a new thread and PM me if I don't catch it right away?

Exactly correct!

Also exactly correct!

This thing should be a sticky !!
It was a life saver for me.
Any idea why this happened ? Is there an issue with 10.4 or was there a later update that I took ?
But - thanks a lot for all who contributed to this simple 2 step solution.. saved me lot of grief.
I've created an account on the forum to just thank you guys !

I think dell-laptop, the module that translates key presses to kernel activity, has been flaky for some time, not just in 10.04. It is ironic that the fix is to just remove it.
See, for instance, posts #3 and 4 here: http://ubuntuforums.org/showthread.php?t=1414946
