WLAN (b43) not working after kernel update to 35.7

nawitus · 2010-10-20 05:37:20

Okay, I have the same problem I had with a kernel update a while ago, my b43 wlan doesn't work. It just says "device not ready" in network manager. Wired connection works.

Weird. Downgraded to 2.6.35.5-1, and the problem persists. I also checked pacman ugprade logs, and I didn't see anything updated related to broadcom..

sultanoswing · 2010-10-21 07:42:02

Don't you have to rebuild and reinstall the driver after each kernel upgrade, by using broadcom-wl from the AUR?

The wiki is quite helpful on this matter, and is what I used to get this chipset functioning on one of my laptops.

No, I don't think I've used "broadcom-wl" ever. As far as I know, "b43" is a driver included in the kernel. Anyway, I'll try broadcom-wl now. Hmm, if I remember correctly, broadcom-wl is the official open source driver, right? Why don't they include it in the kernel I don't know..

EDIT:
Removed "b43-fwcutter". Didn't help. Installed broadcom-wl, didn't help. Upgraded to 35.7, didn't help. Reinstalled broadcom-wl. Blacklisted b43 and ssb etc. Still not working.

nawi ~ $ lsmod | grep wl
wl                   1944061  0 
lib80211                3158  2 wl,lib80211_crypt_tkip

"Device not ready"..

Hmm, it seems that the wlan interface shows up as "eth1", and therefore network manager doesn't see it. It can be changed through "udev" I think. But how?

EDIT: Changed it to wlan0, still doesn't work.

nawi ~ $ iwlist scan
lo        Interface doesn't support scanning.
eth0      Interface doesn't support scanning.
wlan0     Interface doesn't support scanning.

No scanning, so it doesn't seem to be a wireless type of interface?

EDIT: Added "forcedeth" (the module for my etherner card) after the wlan modules. Still nothing.

nawi ~ $ iwconfig wlan0
wlan0     IEEE 802.11  Nickname:""
          Access Point: Not-Associated   
          Link Quality:5  Signal level:0  Noise level:0
          Rx invalid nwid:0  invalid crypt:0  invalid misc:0

EDIT:
I have the same permissions problem here:

Any fixes?

Solved by reverting back to 35.7, reinstalling b43, and reverting the small updates of network manager and wpa_supplicant. Which basically means I'll wait another 6 months to make a new update..
