[Bug 182716] Re: bcm4306, bcm4309, bcm4311, bcm4312 with b43 : Authentification with AP doesn't work.

[naught101]

Interestingly, my wireless fails completely now. I think this might be
since the last kernel upgraded (to 2.6.24-17). Knetwork manager
recognises that the device exists, however it won't find any networks,
regardless of what I do. As soon ad I modprobe either b43 OR bcm43xx,
knetworkmanager recognises that there's a device:

$ uname -a
Linux naught101-laptop 2.6.24-17-generic #1 SMP Thu May 1 14:31:33 UTC 2008 i686 GNU/Linux

$ sudo modprobe -r bcm43xx
$ sudo modprobe -r b43
lsmod returns no instances of b43 or bcm43xx
knetworkmanager doesn't see any wireless device

$ sudo modprobe bcm43xx
$ lsmod | grep bcm43xx
bcm43xx               127720  0

wmaster0 is only created with b43, and not bcm43xx, and it has no wireless extensions:
$ iwconfig
lo        no wireless extensions.
eth0      no wireless extensions.
wmaster0  no wireless extensions.

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

I can't set the card to ad-hoc:
$ sudo iwconfig wlan0 mode Ad-Hoc
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Device or resource busy.

If I can provide any more useful information, let me know what it is an
how to get it.
