Red Hat Bugzilla – Bug 242585
BCM43xx Cards read as ethernet adaptors not wireless
Last modified: 2008-04-22 15:14:56 EDT
Users with Broadcom BCM43xx cards are having much difficulty in connecting to
their wireless networks. I have checked in the network manager and the device
always appears as a ethernet adapter not a wireless one. I believe this is
causing a conflict when the card attempts to connect to wireless network. The
kernel seems to recognize the card and the drivers (often provided through
ndiswrapper) but when connecting it doesn't complete the link. I've managed to
get it to work a couple of times but it is not consistent after reboot. I
believe a patch would be very helpful for many users who are fruitlessly
attempting to get this to work. Thanks!
More likely a driver problem.

Which driver are you using? It needs to be either bcm43xx-mac80211 or
Please see the message I posted on fedora-list here:
Does installing v4 firmware (the first procedure) make things work better? If
not, try the second procedure. Does that make things work?
If you try both procedures above and still have a non-working driver, then
please attach the output of running dmesg and 'lspci -n'...thanks!
This bug is a duplicate of bugs 242338, 243097, 243487, 243585, 244529, and
245084. It' obviously a problem for many users.

doesn't work (at least for me, and, I suspect, for many others).
Please pay attention to this bug. I think it's a NetworkManager problem.
I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.
I am CC'ing myself to this bug and will try and assist you in resolving it if I can.
There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?
If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.
As of kernel 18.104.22.168-65.fc7, my interface works with the b43 driver, but at a
top speed of 1 Mb/s.
I believe I've read somewhere that the speed limitation goes away with the
22.214.171.124 and higher kernels in
http://koji.fedoraproject.org/koji/packageinfo?packageID=8, but I've been
waiting for one of them to make it into updates.

The bcm43xx driver is still very new and a product of reverse-engineering as a
result of broadcom being nigh-on-useless with regards to opening their
specifications. So its more a case of patience I think and hopefully things will
improve, especially with 2.6.23 around the corner.
You may wish to try development kernels with:
yum update kernel --enablerepo=development
and revert to the current stable kernel if you have any problems. If you're
happy with the status quo, feel free to go ahead and close the bug as
essentially the issue appears to be driver-dependent and its just a case of
tracking upstream as close as possible.
Closed due to lack of response...please re-open if/when the requested
information becomes available...
