If you read the previous comments carefully you will find this potential workaround. I can't confirm it works but Broadcom reckon it's a common issue:
[from http://www.broadcom.com/docs/linux_sta/README.txt] * If the wl driver loads but doesn't seem to do anything: the ssb module may be the cause. Sometimes blacklisting ssb may not be enough to prevent it from loading and it loads anyway. (This is mostly seen on Ubuntu/Debian systems). Check to see if ssb, wl or b43 is loaded: # lsmod | grep "b43\|ssb\|wl" If any of these are installed, remove them: # rmmod b43 # rmmod ssb # rmmod wl Back up the current boot ramfs and generate a new one. # cp /boot/initrd.img-`uname -r` somewheresafe # update-initramfs -u # reboot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/732677 Title: bcmwl 5.100.82.38+bdcom-0ubuntu2 not work on BCM4311 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
