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?

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

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

@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?

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.

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.

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.

@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.

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.
