Hello:

Just a follow up ...
I knew I had seen b43XXX *somewhere*. 8^°

> Is the b43 firmware available?
Yes, installers in the Daedalus repositories:

[code]
$ apt list | grep b43
--- snip ---
b43-fwcutter/oldstable 1:019-8+deb12u1 amd64
b43-fwcutter/oldstable 1:019-8+deb12u1 i386
firmware-b43-installer/oldstable,oldstable 1:019-8+deb12u1 all
firmware-b43legacy-installer/oldstable,oldstable 1:019-8+deb12u1 all
--- snip ---
[/code]

One of these should do it.
You can check the package descriptions against the ID of your
chipset.

Best,

A.
