Hello!

It's either bcmwl or b43. Everything you want to know about Broadcom wireless cards, but were afraid to ask, can be found here:

https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#b43%20-%20Internet%20access

This link also tells you how to disable/blacklist conflicting drivers...

No idea if this helps you or not, but I have an older laptop with very similar Broadcom card.


--- Code: ---03:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 02)
--- End code ---

Only difference I see is that yours is "(rev 01)" and mine is "(rev 02)".

I used Synaptic Package Manager (Menu -> System -> Install/Remove Software) to install "bcmwl-kernel-source" package and that worked for me.  Assuming you already purged everything using N4RPS's command -- open Synaptic, type "bcmwl" into the Quick Search bar, select the above package and install it.  Reboot if it doesn't immediately work.  (Don't think you need to get rid of the "linux-firmware-nonfree" that you installed; but if above doesn't work try uninstalling that too.)

Hi Rob,

 It's still not working.

Here's the output:
Ethernet Controller [0200]: Broadcom Corporation BCM4401-BO 100Base-TX [14e4:170c] (rev 02)
Network Controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev01)

Thanks
Rick

N4RPS:
Hello!

NOW we're GETTING SOMEWHERE. You have a BCM4311. NOW try THIS: In a terminal window [CTRL-ALT-T], enter the following:


--- Code: ---sudo apt-get remove --purge bcmwl-kernel-source firmware-b43-installer firmware-b43legacy-installer
sudo apt-get install linux-firmware-nonfree
--- End code ---

You shouldn't have to, but if it doesn't fire up right away, reboot. If it's still broken after that, tell me the number XXXX in 14e4:XXXX...
