Re: Broadcom 4311 network adapter doesn't work under Jessie (was debian-user-digest Digest V2015 #1143)

You can search for respective driver on kernel.org, and also Google it. Also, you can search for the required firmware on your manufacturer's website.
Good luck!

I'm also using an old laptop with an old B43 wireless NIC.  I have also
had a little trouble making it work, but after some effort have got it
pretty well figured out.  Make sure that the b43 driver package is
installed (firmware-b43legacy-installer).  You will also need the
b43-fwcutter package to obtain and install the proprietary firmware for
the NIC. Installation of the firmware package will require internet
access as it downloads the firmware from Broadcom.  As I recall, the
b43-fwcutter package is automatically installed when you install the
firmware-b43legacy-installer package, but you might want to make sure
that that is true.

Once you install these packages, reboot the system!! (I forgot to do
this once, and spent quite a bit of time scratching my head wondering
why my NIC didn't come up.)  When the system boots up, it will load the
firmware into the NIC and you should be good to go.  Be sure to be
patient when booting the system, the wireless card may not come up until
just about the time the login dialog appears on the screen.  That's the
way mine works, so don't get worried if the light for the wireless card
doesn't come on right away when the system starts booting, it may be
nearly login time before it does.
