[SOLVED] BCM4312 wifi chip kernel: b43 ssb0:0: firmware: failed to load b43/uc

I have an old Dell vostro 1015 laptop with a BCM4312 chip that is detected but has errors. The previous posts from 2022 did not help.

Re: [SOLVED] BCM4312 wifi chip kernel: b43 ssb0:0: firmware: failed to load b43/uc

Install the firmware-b43-installer package. That includes a script to extract the firmware from the old Broadcom STA driver, which will then be usable by the in tree b43 driver. You will need to reboot or unload and load the b43 module for it to work.

Re: [SOLVED] BCM4312 wifi chip kernel: b43 ssb0:0: firmware: failed to load b43/uc

I added deb http://deb.debian.org/debian/ bookworm main contrib non-free to my sources.list and installed  the firmware-b43-installer package and it worked!
I commented the line afterwards.
Thanks David
