I'm inclined to believe this is simply local to your system: 1) You did not get linux-restricted-modules in your upgrade. This would cause 3945 to not work. Run "sudo apt-get install linux-generic"
2) You need to move your bcm43xx firmware to /lib/firmware/ (and not in some version specific subdirectory). This would cause bcm43xx to not work. ** Changed in: linux-source-2.6.17 (Ubuntu) Status: Unconfirmed => Rejected -- Dell Inspiron 9400 network support lost https://launchpad.net/bugs/66454 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
