Broadcom wireless drivers fail after upgrading kernel

I installed the broadcom wireless drivers from here http://www.broadcom.com/support/802.11/linux_sta.php (the 32-bit version). I was using kernel version 2.6.26 at the time. I followed the instructions on the wiki page http://wiki.archlinux.org/index.php/Broadcom_BCM4312 . To get it to work each reboot I had to run these commands "modprobe ieee80211_crypt_tkip" "insmod /lib/modules/2.6.27-ARCH/kernel/drivers/net/wireless/wl.ko". This worked perfectly and I could connect to the internet and everything. The wireless device showed up under "eth3". I then upgrade my kernel to 2.6.28.1 and reboot. Now two new wireless devices show up "wlan0" amd "wmaster0" without me entering any commands. Wlan0 was the wireless device. I tried entering in my essid, but it wouldn't associate with the access point. I tried running the commands as normal and it didn't help. I confirmed the b43 drivers are blacklisted as well. I then ran lsmod and realized I had a weird wireless driver running "rtl8187" I blacklisted that too, rebooted, and reinitialized the drivers. Doing that got rid of the wlan0 and wmaster0 devices, but still no luck.

Re: Broadcom wireless drivers fail after upgrading kernel

Go to archlinux wireless and use the wl driver

broadcom-wl

For recent Broadcom 43xx cards not supported by bcm43xx or b43. Not just for 4312 cards. See the Broadcom 4312 wiki page. It is available in AUR. These chipsets are used in most Dell laptops, among others.


You may have to load the wl.ko driver manually insmod wl.ko from the directory you have the driver.  Before you load the wl.ko driver make sure that the ieee80211_crypt_tkip is load (lsmod)  Make available 802.11 TKIP crypto module:      modprobe ieee80211_crypt_tkip
3.  Insert the Broadcom wl module:                 insmod <path>/wl.ko

Re: Broadcom wireless drivers fail after upgrading kernel

If you want to continue using the wl driver, you need to rebuild it against the new kernel.

I did rebuild it, duh. And I don't understand what viga was saying, I used the drivers from here http://www.broadcom.com/support/802.11/linux_sta.php which were the ones that the wiki page (http://wiki.archlinux.org/index.php/Broadcom_BCM4312) said to.
