Wireless just stopped working

**dbbolton** · October 13th, 2009

Here is some info on my card:

Code:

0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01)
    Subsystem: Dell Device [1028:000b]

    Kernel modules: wl

The wireless was working fine. After unchecking "Enable Wireless" in the nm-applet context menu, I have not been able to re-enable it. It seems that nm-applet no longer sees any wireless network.

I tried clicking "connect to hidden network" and then entered my home network info, but that didn't work either.

lsmod reports that wl is in fact loaded.

I suspect this problem has something to do with NetwrokManager, but I really don't even know how to approach it.

Does your keyboard have a wireless card button? It may look like a small graphic of a radio tower, and it is meant to disable wireless functions as you may need to on a plane, for example. Hitting it again should turn the wireless card back on if that it the cause.
