wifi broadcom 4306

[thornspear]

After finally getting my usb wireless working, I thought I'd try and get the onboard wireless going too. I found the link below while searching for a fix, and wondered if it still would apply to Ubuntu 9.04. I don't have the same file name under etc/udev/rules that is mentioned. Mine is 70-peristent-net.rules instead of z25-persistent-net.rules.

Here's the link:

http://www.linuxforums.org/forum/wir...43-module.html

I did try and delete the file (I backed it up first) and reboot. There was no automatic change when I rebooted. I still couldn't see any available wireless connections (and there are a few here).

I checked the new file that was created after the boot, and noticed the file size had changed. So I replaced it with the old larger file I had backed up.

any ideas?

Can you post the output of

lspci -nn

There are two version of the 4306, according to the b43 wireless page, one might work better with the b43-legacy driver, and one should work fine with b43 driver.

I would try installing the firmware for the card and seeing if there is any trouble before messing with udev rules. That was an older post, using an older release and kernel, so the bug may well be fixed.

For Ubuntu, if you have a wired connection, all you need to do for the firmware is

sudo apt-get install b43-fwcutter

It will ask if you want to download and install the firmware - say yes.

[thornspear]

firmware is already installed.

[thornspear]

is it at all possible that the sound controller is interfering with the modem controller?

This should be supported fine by b43. Please post the output of

lsmod
iwconfig
dmesg | grep b43

I've never heard of the sound controller interfering with the b43 driver, but I don't really know.

thanks for helping reed9

[reed9]

Hmm, everything seems ok.

Can you see networks in the networkmanager? Or you can see them and it just spins and times out?

Does

sudo iwlist wlan0 scan

list available networks?

What's the output of

dmesg | grep wlan0

You can try loading and unloading the module.

sudo ifconfig wlan0 down
sudo modprobe -r b43
sudo modprobe b43
sudo ifconfig wlan0 up

[thornspear]

No. It shows absolutely no available networks under my broadcom card for some reason. I'll try loading and unloading.


iwlist

wlan0 No scan results
