no wireless on macbookpro 5,5

[ichigo]

Hi,

my wireless has stopped working about a week ago. I was using the proprietary drivers that were automatically installed by ubuntu. The card still shows up in lspci, but does not in the network manager. With "lshw -C network" I get the following output:

           *-network UNCLAIMED
                description: Network controller
                product: BCM4322 802.11a/b/g/n Wireless LAN Controller
                vendor: Broadcom Corporation
                physical id: 0
                bus info: pci@0000:03:00.0
                version: 01
                width: 64 bits
                clock: 33MHz
                capabilities: bus_master cap_list
                configuration: latency=0
                resources: memory:d3200000-d3203fff

I've googled for it and found out that lshw labeling the device as "unclaimed" probably points to a driver problem. Since all guides I found for this card say, things work out of the box, I don't know what I shoud do?
Any ideas?

UPDATE: Problem SOLVED: Uninstalling linux-backports-modules... did the trick

i would just reinstall the proprietary driver here

Thx for the hint. I've tried to install it as the readme says but get stuck at point 4.:

inago@Naoshima:~/Desktop/broad$ sudo modprobe lib80211
WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.
inago@Naoshima:~/Desktop/broad$ sudo insmod wl.ko
insmod: error inserting 'wl.ko': -1 Unknown symbol in module

Don't know if it helps, but the output of the compile looked like:

 sudo make
KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`
make[1]: ディレクトリ `/usr/src/linux-headers-2.6.31-19-generic-pae' に入ります

did you install the kernel source ?

[ichigo]

did you install the kernel source ?

I guess you mean the linux-headers-2.6.31-19-pae package. Yes, it is installed.

If you compile some modules against the kernel, you need to have the kernel source installed. Correct me if I'm wrong.
