Wireless Card won't work after update to Kernel 3.0

Good afternoon people,

I have just updated my ArchLinux installation and now my Wireless card won't work anymore (even after loading the modules)
When I run a 'iwconfig wlan0' it will say that the device does not exist.
The wireless card is a Broadcom 4313 in a Dell Vostro 3500.

Below the output of lspci

I have also noticed that the package initscripts has been updated to version 2011-07.3 and now any modules in the MODULES array in rc.conf won't be loaded anymore during boot. I had this same problem 2 weeks ago, and I had to downgrade the initscripts to the prior version in order for everything to go back to normal. Thing is that now I am having a bad time to do that, because my wireless card won't be recognized somehow.
Any ideas?

Thanks!

Re: Wireless Card won't work after update to Kernel 3.0

Just as an update... I downgraded the initscripts to version 2011.06.4-1 and now I am able to see my wireless card again. Problem is that now everything got a little unstable (the card isn't able to get an IP address anymore and the system won't reboot anymore).
Any ideas?

Re: Wireless Card won't work after update to Kernel 3.0

Gilgamesh, please edit your post.
When pasting code, please use [ code ] tags https://bbs.archlinux.org/help.php#bbcode

like this

It makes the code more readable and more convenient to scroll through.

Post the output of

ls -1 /etc/modprobe.d/

Re: Wireless Card won't work after update to Kernel 3.0

Sorry, I have fixed that.

Here is the output for the command you asked:

blacklist_net.conf
blacklist_sound.conf
modprobe.conf
usb-load-ehci-first.conf

Re: Wireless Card won't work after update to Kernel 3.0

Ohhhh... I just checked the contents of those files, and my modules are all listed there... I wonder why they are listed there? Everything was working prior this update.
Any ideas?

Re: Wireless Card won't work after update to Kernel 3.0

It's a bug. https://bbs.archlinux.org/viewtopic.php … 74#p968474
Remove blacklist_net.conf and blacklist_sound.conf but keep the other two.

Re: Wireless Card won't work after update to Kernel 3.0

Great! I've done that and now my card shows up. Thing is, when I try to get an IP address, it won't work. Here is the command output:

ieee80211 phy0: wl_ops_config: change monitor mode: false (implement)
ieee80211 phy0: wl_ops_config: change power-save mode: false (implement) 
ieee80211 phy0: wl_ops_bss_info_changed: qos enabled: false (implement)

And then it times out and no IP is assigned. The thing is, wpa_supplicant stays alive after this time out, and I am unable to kill it (killall -9 wpa_supplicant won't kill it). At this point if I try to reboot the machine, it will stop at 'Rebooting' and won't go anywhere. If I turn off the wireless card in its switch Linux crashes. If I try to get an ip again (by running dhcpcd) the command will hang and not return to the shell anymore.
I am unable to find any useful information in the logs.

Got any more suggestions?

Thanks! (And sorry to disturb so much)

Re: Wireless Card won't work after update to Kernel 3.0

You seem to have b43, b43legacy, and bcrmsmac all loaded, which could be causing your problems. If you are using bcrmsmac (which you should), you should blacklist b43 and b43legacy. Also you may have trouble after unloading those modules as well (the interface won't show up in if/iwconfig). If that is the case, also try blacklisting bcma (this part fixed it for me).

tl;dr Add this to /etc/modules.d/modules.conf

blacklist b43
blacklist b43legacy
blacklist bcma

and see if it works then.
