No wireless in 9.10 with Broadcom BCM4312

[Gravy]

Returns:

linux-image-2.6.31-14-generic: /lib/modules/2.6.31-14-generic/kernel/net/wireless/lib80211.ko
linux-backports-modules-2.6.31-14-generic: /lib/modules/2.6.31-14-generic/updates/cw/lib80211.ko

ok, so you still have linux backports installed. There shouldn't be anything you need in there, but if you lose any functionality when you remove just note it and you can add it back.

wl was probably built against /lib/modules/2.6.31-14-generic/kernel/net/wireless/lib80211.ko, but depmod is compiling symbols from the "updated" /lib/modules/2.6.31-14-generic/updates/cw/lib80211.ko.

Run sudo apt-get remove linux-backports-modules-2.6.31-14-generic to remove the backports. The run depmod -a and modprobe wl as root.

And keep fingers crossed

[Gravy]

Finger crossing wasn't enough.

It's somehow still finding an unknown symbol there.

FATAL: Error inserting wl (/lib/modules/2.6.31-14-generic/updates/dkms/wl.ko): Unknown symbol in module, or unknown parameter (see dmesg)

[pjomega]

ok, run modprobe wl and then immediately dmesg|tail, which will give you the tail end of the system message log. What's it complaining about?

[Gravy]

Same error as earlier which there is this bug report for:
https://bugs.launchpad.net/ubuntu/+s...wl/+bug/395630

[  335.063603] wl: Unknown symbol lib80211_get_crypto_ops

[pjomega]

rebooting should fix that. but you should be able to effect it without rebooting. look at that bug report comment #4. as root remove those modules, add them back, and then load wl:

[Gravy]

Returning:

ERROR: Module lib80211 does not exist in /proc/modules

Think I probably messed them up earlier. :s

[pjomega]

even after running sudo insmod /lib/modules/2.6.31-14-generic/kernel/net/wireless/lib80211.ko?

[Gravy]

I ran that again and I could execute the .ko but none of the others.

[pjomega]

hmmm...that's a problem. is that one of the ones you deleted? does ls /lib/modules/2.6.31-14-generic/kernel/net/wireless/ not show them?
