Broadcom BCM 4311 network unclaimed, no wireless

[weidnerr]

Thanks for your post mauleshjani...

I did a fresh install of 12.04 yesterday.
Can get on wired but wireless network is UNCLAIMED

I have BCM4311
Vendor: Broadcom

Hardware
Network: After doing your steps I now see the wireless network which wasn't there before.
The problems is firmware is missing and when I install and activate the Broadcom STA wireless driver supplied with 12.4 and reboot I completely lose the wireless network again.

Tried three times and the same outcome each time.

Hi, try:

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source

Then:

sudo apt-get install linux-firmware-nonfree

Reboot
Thanks

Hello! I just had the same problem while installing ubuntu 12, through the install everything was fine, i was even able to connect to the wifi, and even when i started using it everything was fine, but as soon as i updated some packages, and restarted (as it asked), it stopped working. I've followed what you said here, and i got the same problem as OP, *-networ UNCLAIMED with broadcom when i run sudo lshw -C network. Thanks.

Hi, copy and paste this command in the terminal (ctrl+alt+t) please:

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back, click on the paper clip and attach the netinfo.txt file.
Thanks

Thank you for the extremely quick reply! I actually didn't see that until now. I choose to re-install ubuntu, as it was fresh and i had some time, it seems to be working right now, altough it didn't asked me for updates this time. Again, thank you, and sorry for not reading that earlier.

Your welcome! I suspect when you update it will happen again.
