[gentoo-user] trouble with broadcom wireless

[Allan Gottlieb]

Dell latitude E6510, ~amd64
kernel: 2-6.34 (gentoo sources)

lspci -vnn
03:00.0 Network controller [0280]: Broadcom Corporation Device [14e4:4727] (rev 01)
	Subsystem: Dell Device [1028:0010]

If I understood the wiki correctly, with the new kernel I don't have to
run b43-fwcutter, but just emerge the b43-firmware.  I have done so and
also have the fwcutter emerged.

I have build b43 as both a kernel module and as a built-in component.
But neither eth1 nor wlan0 exist for either kernel configuration (eth0
is the hardwired ethernet)

I suspect there is another step I should be doing and would appreciate
any help you can offer.

thanks,
allan

Are you sure this is a B43xx devices, the lspci output doesn't specify?
Some Dells use a different Broadcom card that needs the
net-wireless/broadcom-sta module to be emerged.

Mine is a different Broadcom card:

05:00.0 Network controller [0280]: Broadcom Corporation BCM4312
802.11b/g LP-PHY [14e4:4315] (rev 01)


but my kernel settings may help here:

$ cat /usr/src/linux/.config | grep -i b43
CONFIG_B43=m
CONFIG_B43_PCI_AUTOSELECT=y
CONFIG_B43_PCICORE_AUTOSELECT=y
# CONFIG_B43_PCMCIA is not set
# CONFIG_B43_SDIO is not set
CONFIG_B43_PIO=y
CONFIG_B43_PHY_LP=y
CONFIG_B43_LEDS=y
CONFIG_B43_HWRNG=y
CONFIG_B43_DEBUG=y
CONFIG_B43_FORCE_PIO=y
# CONFIG_B43LEGACY is not set
CONFIG_SSB_B43_PCI_BRIDGE=y

I couldn't get it to show up until I selected the debug feature with
the FORCE_PIO option.

(I tried Mick's kernel settings, but with no effect).

Neil's suggestion to use broadcom-sta was the solution.  It took some
effort to get the module to build, but was possible.

thank you both.
