View Full Version : [ubuntu] Wireless stopped working suddenly

February 7th, 2009, 06:55 PM
I'm using a Dell XPS M1530 laptop with Ubuntu Hardy Heron. Last night the update manager ran, and it installed some new stuff, including a new kernel (2.6.24-23.48). It seemed to run okay, and I used it a few times without problems. I went to shutdown, and it locked up on me. I used the power key to turn it off. In the morning, I fired it up, and it can't find any wireless connections.

I've checked the bios, and the wireless is still enabled there.

I tried to follow the help, and here is the output of lshw -C network:

The DISABLED part looks weird to me I guess. How do I enable it? I can use the network manager in the top tool bar, and if I right click on it, it says that wireless is enabled.

I did try booting older kernels but it didn't help.

Any advice? Thanks.

Well don't I feel dumb.

Apparently there is a little slider switch on the right side of my laptop to enable/disable wireless. Didn't even think to check that.

Works great now! ](*,) :p
