Greetings, Ekeis & Klaus2008

This is disturbing news, I think.
Make sure you haven't inadvertently blacklisted wl, if that's what you need.

I've been happy with Knoppix since 6.2; I haven't seen 7.0 yet.
I have the BCM4312 and have been using the wl driver all along.
See for example, with my current 6.7.1:
Code:
knoppix@Microknoppix:~$ lspci | grep -i bcm; lsmod | grep wl
0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
wl                   1936903  0
My wl has always been loaded without any hassle at all. Up til now?

If wl is needed and isn't provided automatically,
the bcmwl source is available via synaptic, BUT
it's a real hassle to install. I've complained about with Ubuntu
and all its clones.

Conversely, if you need b43, make sure that's not blacklisted.
