Concerned hardware :
02:09.0 Network controller [0280]: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller [14e4:4320] (rev 03)
        Subsystem: Linksys Unknown device [1737:0013]
        Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
        Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 32
        Interrupt: pin A routed to IRQ 19
        Region 0: Memory at fdffe000 (32-bit, non-prefetchable) [size=8K]

The concerned card is a Linksys WMP-54g
After upgrading from Gutsy to Hardy, I blacklisted the ndiswrapper module and the bcm43xx one to try the b43 one (I used b43-fwcutter and the correct file to extract firmware).

After rebooting, the network doesn't work and only does if I unload ohci-hcd, ssb, b43 and modprobe bcm43xx.

If I unload everything and modprobe b43 :

ifconfig -a returns :

lshw -C network returns :

At this point, restarting the network gives :

Now, if I modprobe -r b43 && modprobe bcm43xx :

and I have a working network (and reload ohci-hcd).

Last attempt then : blacklist b43, add bcm43xx in /etc/modules and reboot and it doesn't work. lshw returns «configuration: driver=b43-pci-bridge latency=32 module=ssb».

It is working if I blacklist b43 in /etc/modprobe.d and (very very badly) blacklist ssb (renaming ssb.ko). Only trouble then, ohci-hcd can't load :

I hope this is clear enough :-)
