Upgraded to 13.04 over the weekend with fresh install of the official 13.04 distro. Afterwards the networking icon shows:

No network devices available

Installed onto a Dell XPS M1210. No network connectivity for Ethernet or WiFi. Yellow lights are are on when Ethernet cable is inserted. Any help is appreciated.

The Broadcom controller does show up in the output:

 sudo lshw -C network

Tried "sudo apt-get remove --purge bcmwl-kernel-source" and then reinstalled the bcmwl-kernel-source package from the USB following instructions here: acervulus.info/2011/… On reboot wired LAN worked and I could do a update and upgrade. But failed on subsequent reboot! –  dimeo May 5 '13 at 17:16

Tried "sudo dpkg-reconfigure bcmwl-kernel-source" and rebooted. Then LAN connected again. But still no wireless connection, however now BCM4311 is visible under "Additional Drivers" in Software and updates. –  dimeo May 5 '13 at 17:24

Wireless worked by: $ sudo apt-get install firmware-b43-installer $ sudo apt-get remove bcmwl-kernel-source Then reboot. Source: nfolamp.wordpress.com/2011/10/15/… –  dimeo May 5 '13 at 19:17
