View Full Version : [ubuntu] Broadcom Corporation BCM4311 WLAN card no longer working

January 19th, 2009, 11:19 PM

I've been happily using Ubuntu Intrepid Ibex 8.10 fully patched as patches come out since early Dec. 2008. I've had great success, including with the proprietary wifi drivers for my built-in Broadcom BC4311 b/g wlan card. I use this system at home with my Netgear wireless b/g router, using WPA2 encryption. Wifi has been starting on it's own just fine, with this laptop having no problems automatically connecting to my home network after a reboot. Now, just yesterday, after accepting an ACPI update (can't remember the number, but it came out around 1/14/2009 or so) and doing a reboot, I can no longer get WIFI to work, no matter what I do, or change. Keep in mind, I have been using linux of some sort since the '80s and my day job is a systems admin for a variety of systems, mostly linux and windows. I'm also accomplished at hardware and networking, so feel the last 30 hours of me banging my head against the wall is not worth it.

After trying many things in the Ubuntu forums and having none work, I decided to re-install from scratch. I've now done that, installed updates via the wired connection and again enabled the BC43 proprietary drivers found in System->Admin->Hardware drivers. A reboot, etc., tell it manually my SSID, WPA key, etc. (ensuring the MAC address is in the router - again this was working so MAC access list in the router shouldn't need to be changed). Still no dice - all I get is that the radio is DISABLED (dmesg) even though the wireless box is checked in the network GUI (gnome) and the blue light is on on the front of my laptop.

Here's all the specifics as required:

And of course no wifi when I do this. Same message in dmesg - DISABLED. I think this would all work normally (the way it did just a day or so ago), if I could actually get the card turned on, or at least get the system to realize it's on and enabled (wireless is turned on in network manager and blue light is on on front of laptop).

An additional piece of info., before this happened, I didn't have to turn off the physical wlan switch on the laptop, deselect wireless in the network manager, turn on the switch and then re-enable wireless in the network manager. It just worked. Now, to even get the light to turn blue, I have to do the procedure I just described.

Going to stick another hard drive in with Vista (yuk) so I have a laptop with wireless. Hopefully, there's enough info. in here for someone more knowledgeable about wireless linux drivers than me to present me with more solutions than the countless I've tried.

Thank you,
