Wireless drivers don't seem to work any more

I have a BCM4322 wireless card:

$ lspci | grep -i net
00:19.0 Ethernet controller: Intel Corporation 82567LM Gigabit Network Connection (rev 03)
0c:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)

I've been using the broadcom-wl driver for a while, which worked fine until recently. I did a full pacman upgrade (which included the switch from kernel26 to linux 3.0) and now it doesn't work any more. Here's some stuff I did any the results reported:

$ sudo modprobe wl
$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

$ sudo rmmod wl
$ sudo modprobe b43
$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     IEEE 802.11bg  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:on

$ sudo ifconfig wlan0 up
SIOCSIFFLAGS: No such file or directory

So I'm at a loss now how to fix this. Anyone have any ideas?

Re: Wireless drivers don't seem to work any more

I think you need to rebuild the broadcom-wl package with the new kernel installed to update the module.

Re: Wireless drivers don't seem to work any more

I would advise to have a look here for instructions on using the in-kernel driver: https://bbs.archlinux.org/viewtopic.php?id=111554&p=6

Re: Wireless drivers don't seem to work any more

@karol: I did reinstall the broadcom-wl driver from the AUR after the upgrade, to no avail.

@litemotiv: That thread seems to be about the brcm80211 driver, which isn't compatible with the BCM4322 chip. Is it relevant to my problem too?

Re: Wireless drivers don't seem to work any more

http://wireless.kernel.org/en/users/Dri … ed_devices suggested that my chip (the 14e4:432b variety) might partially work with the native kernel driver. I installed the b43-firmware package from the AUR and things seem to work fine, so I think I will stick with that solution.

Re: Wireless drivers don't seem to work any more

First try

modprobe wl

and check if now your broadcom wlan is working.

If that works you should also check the /etc/modprobe.d/blacklist* files and seach for the module "wl"

grep wl /etc/modprobe.d/*

if there is any line like

blacklist wl

edit the file and comment it out with a # out

#blacklist wl

Learn the facts, and the origins behind the facts, and make up your own damn mind. That's why you have one.

Re: Wireless drivers don't seem to work any more

I have this same problem right now.  I have a broadcom bcm4312 card and am using broadcom-wl from the AUR.
It was working fine until today, not sure why.  Yesterday I had done a kernel upgrade and had recompiled the module.  Today it was working and then while in the middle of watching a video online, my card seemingly quits, all connection lost.  I try looking for wireless networks and none are found now.  I rebooted, and nothing.  I recompiled wl again and still nothing.  The module is currently running (verified through lsmod | grep wl) but wireless internet is not working at all.

Re: Wireless drivers don't seem to work any more

@iimblack: Same advice as before, try the in-kernel b43 driver. Your card should be fully supported by it. You need the b43-firmware package from AUR.

Re: Wireless drivers don't seem to work any more

My card unfortunately has some hiccups with the B43.
Anyways, problem solved for me.  It ended up that I had a hardware problem, not a software one.  That's why my wireless went out in the middle of use without changing anything.  Weird stuff.
