seeking driver for Broadcom BCM4312 (rev01) for Ubuntu 9.04
 

I have a Gateway laptop with a Broadcom BCM4312 802.11a/b/g (rev01) wireless card. I'm running Ubuntu 9.04 (2.6.28-15) with no problems other than the wireless.

I've installed the required firmware and the wireless networks in my area are now visible. However, I cannot connect, and drivers for BCM4312 are not readily available for the rev01 version.

Does anyone have a driver for this wireless card, specifically rev01?

I'd rather not use NDISwrapper.

Which driver are you currently using? (There are two FOSS drivers: bcm43xx and a newer one, b43.) A dmesg | egrep -i '(b43|bcm43)' in a terminal window should tell you which one you're using.

AFAIK, the newer b43 driver should support the rev01 hardware. Note that the support depends on you extracting the correct firmware, so you need to also make sure you've extracted from the correct object code file.
