Can't get wireless working on 2008 laptop (Acer Extensa 5220) running Debian 12 (worked on Debian 11).
 
Hi.

I expected the wifi to get sorted during install but no joy.

This worked for Debian 11, 10 and a few others: https://wiki.debian.org/wl#Broadcom_...vices_.28wl.29

I installed all the broadcom entries in Synaptic and rebooted, no change.

How can I the wireless going in Bookworm?

Thanks.

Have you got 'non free firmware' in your sources list(?) - they separated out wifi, etc.

Hi.

My sources list is:

Code:
deb http://deb.debian.org/debian/ bookworm main non-free-firmware
deb http://security.debian.org/debian-security/ bookworm-security main non-free-firmware
deb http://deb.debian.org/debian/ bookworm-updates main non-free-firmware
deb http://deb.debian.org/debian bookworm-backports main contrib non-free

Maybe check that a module is being loaded...

Code:
lsmod | grep bcm

There is another thing to check...
Code:
sudo rfkill list
&
Code:
sudo rfkill unblock all
Then, maybe, that is the wrong module; try inserting other bcm modules, to see if your wifi will work; then if it does, blacklist the one that was originally loaded by the system.

Otherwise, I can't think of anything else...

My WiFi card is a Broadcom BCM94311MCG.

I didn't have my sources configured properly - needed more contrib on the lines. Now the b43 packages are available.

linustalman 10-15-2023 11:38 AM
I ran these commands and all seems fine.

Code:
sudo apt install firmware-b43-installer
sudo modprobe b43
sudo reboot

Glad you got it sorted out. :)

Thank you.

I wonder if I should also do steps 2~7 here or if those are not needed for Bookworm.

If it's working OK, I'd leave things as they are.... :D

The old proverb - If it ain't broke, don't fix it. ;-)

Some laptops have physical switches or keyboard shortcuts to enable or disable wireless. Ensure that your laptop's wireless hardware is turned on. Look for a wireless switch on the sides or front of your laptop, or use the appropriate keyboard shortcut.
