wireless issue please help

[tongueman]

hi all, hope someone can help..

My wireless has been working fine for months now and was earlier today but now it wont connect wirelessly, in fact my computer doesn't even recognise that a wireless adapter is present as usually i can see about 6 networks to join. i've tried disabling the driver and re installing it but still nothing. my adapter is....

05:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

What has happened? ?Usually i just turn laptop on and it connects automatically.

Any help would be much appreciated. Many thanks

try to install b43
sudo apt-get install b43

[thornspear]

If those don't work try

sudo apt-get install b43-fwcutter


I tried sudo apt-get install b43 and it wasn't found... My broadcom wireless doesn't work either...

What driver were you using? In your case there is a Broadcom proprietary driver that may be best suited. It is the wl driver, but is also called the Linux-STA driver.

It should be available through the Hardware Drivers GUI, found here:

System-->Administration-->Hardware Drivers

There is a native Linux driver called b43 that may also be used. If this driver is also loading, then the wireless will just be confused and cease to work. Post the output of this command.

lsmod

I was using the propriety driver and it was working fine but all of a sudden it stopped working.
Thanks for having a look, here the results:

You most likely were using the wl diver module, and a kernel update didn't include it. You can try to load it manually.

sudo modprobe wl

What does the Hardware Drivers section say about the wireless driver?

[tongueman]

the hardware driver states:

'This driver is activated and currently in use'

sudo modprobe wl didnt do anything i'm afraid.

thanks

[waterhead]

By "didn't do anything" do you mean the terminal just returned a blank prompt? That is what it is suppose to do when it loads a module. Afterwards check the output of lsmod again for the wl module.

What is the name of the driver that the Hardware Drivers section says is "activated and currently in use"?

[tongueman]

really appreciate your help with this...

It shows that the wl module is now loaded. Are you still having trouble connecting? Try deleting your saved connection, and connect as a new connection.
