Broadcom 802.11 Linux STA wireless driver problem?

[mikewhatever]

Hm..., interesting. Can you post the outputs of the following:

dpkg -l | grep bcmwl

dmesg | grep wl

lsmod

[23senick]

$ dpkg -l | grep bcmwl

OK, thanks for the outputs. If you've followed the thread suggested by Hadaka, try removing the linux-backports-modules-cw-3.6-precise-generic package, then reboot:

sudo apt-get purge linux-backports-modules-cw-3.6-precise-generic

It caused the same problem for others with the wl module.

Thanks Mikewhatever - I'll give it a go in a bit and post back. Just had to surrender the laptop to someone with homework to do!

[23senick]

Success!! Thanks mikewhatever.

When I did the sudo apt-get purge, I got this message:

The following package was automatically installed and is no longer required:
linux-backports-modules-cw-3.6-3.2.0-37-generic
Use 'apt-get autoremove' to remove them.

I first of all tried rebooting without doing this, and got back to where I had started (seeing wifi network but not connecting). So I did apt-get autoremove and on startup, again, it wouldn't connect. I disconnected from wifi network, left it a few minutes, and when I tried again it connected. Tried a reboot...immediate connection.

Hope others find this helpful. Should the thread be marked solved, I wonder?

So we got two happy campers here

Nicely done mike!

@ 23senick,
Next time you have to post some command output, please consider enclosing them in 'Code' tags. It preserves the output's formatting and makes it more readable. I've edited your above post as an example. You may follow the 'example' link in my signature to see an example of how to do it yourself
