ReH3565:
I just downloaded linuxlite. I had no problem with internet connectivity using an ethernet cable but my wireless network wasn't recognized. I searched for additional drivers to get my Broadcom wireless activated, downloaded the driver, and now neither wireless nor wired internet will work. How have I messed up?

Irishluck83:
If you just downloaded the driver you will have to reboot. Come back if it still not connecting.

Hello!

Depending on the make, model, and age of your computer, there are several possible Broadcom drivers out there. Open a terminal window [CTRL-ALT-T] and enter the following command:


--- Code: ---sudo lspci -nn -d 14e4:
--- End code ---

Post the output here, and I'll tell you how to find the right driver. If you've installed the wrong one, you'll have to uninstall it to install the correct one, which I'll tell you how to do as soon as we determine which one you need.

Here's my output as an example:

[email protected]:~$ sudo lspci -nn -d 14e4:
02:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)

Older models use the b43 driver, and the REALLY ANCIENT ones use b43-legacy.

Hope to hear from you soon...

Hi,

Here is the output:

Ethernet controller: Broadcom BCM4401 - BO 100Base - TX
Network Controller: Broadcom BCM4311 802.11b/g WLAN

Thanks

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...
