Problems with Broadcom wireless card after Kernel Upgrade

After upgrading to version 2.6.39 of the linux kernel, I am having trouble with my Broadcom BCM4312 wireless card. The broadcom-wl driver no longer seems to work, even after reinstalling it from the AUR. The b43 driver seems to be able to connect to unencrypted networks, but can no longer connect to my family's WPA Personal encrypted router. Is anybody else having a similar problem?

Re: Problems with Broadcom wireless card after Kernel Upgrade

for the broadcom-wl driver, simply reinstalling your previously compiled version won't work. broadcom-wl has to be recompiled for each major kernel upgrade, so the copy of broadcom-wl that you compiled for 2.6.38 won't work with 2.6.39.

I've already recompiled it and it still doesn't work.

OK, nevermind, broadcom-wl doesn't work at all. b43 can connect to unencrypted  but not to encrypted

I've already recompiled it and it still doesn't work.

Recompile it in a clean build directory. Saying it "doesn't work" is never specific, or helpful.

Re: Problems with Broadcom wireless card after Kernel Upgrade

As I understand it my laptop has been fine and it uses broadcom-wl, and I just re-yaourt it each time my kernel version changes using a cable in my router. But I believe there is something called dkms and a version of the driver for it, which (I haven't read fully into it) is something like a separate tree, which can (from what little I've read) eliminate this need to recompile every time, however I literally read this 5 minutes ago, from the AUR page for broadcom-wl and a quick google so I wouldn't be surprised if there is more to it than that.

Re: Problems with Broadcom wireless card after Kernel Upgrade

I'm having no trouble with broadcom-wl on my laptop. I always recompile broadcom-wl after upgrading to a new major kernel (and don't forget to change all the 'uname -r' to '2.6.39-ARCH' in this case).

I also saw there was a package with DKMS-support - could prove interesting.

Nevermind, guys, it seems the b43 driver has automagically started working again.
