Dell E6400 - broadcom 4312 wireless not working

Hi all - thanks to this forum I managed to get wireless working on a D620 laptop OpenSUSE 11.3 and Dell D620 - wireless LAN not working. Now I have a similar problem with an E6400, also with Broadcom wireless.

I have successfully installed the b43 firmware using /usr/sbin/install_bcm43xx_firmware, and I have successfully installed the packman drivers broadcom-wl and broadcom-wl-kmp-desktop (my kernel is via YaST package search.

When using Network Manager, the Wireless tab is greyed out and can not be configured. When using ifup, the BCM4312 appears as wlan0, but I get no wireless connectivity.

/sbin/lspci -nnv | grep 14e4

0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)


lo no wireless extensions.

eth0 no wireless extensions.

/usr/sbin/iwlist scan

lo Interface doesn’t support scanning.

eth0 Interface doesn’t support scanning

dmesg | grep b43

Any ideas what I’m missing here? The only thing that jumps out at me is that the b43-firmware and *b43legacy-firmware * entries in package manager are not installed, but those are also not installed on my D620 laptop where wireless works perfectly.
