Christopher, As stated in comment #4, wifi does work correctly now. In the meantime I have upgraded my laptop to Ubuntu 13.04.

It is more likely (almost 100%) to happen if the machine hasn't been used for several days (which suggests to me it has something to do with obtaining dhcp leases). And even with the steps below, sometimes the wifi will work from the beginning as expected. However, steps that increase the chances to reproduce it are: * boot into ubuntu. * turn off wifi with the rfkill switch * sudo rm /var/lib/dhcp/dhclient* * reboot the system. At the GRUB screen, turn on the rfkill switch again, so that wifi is enabled at boot time * log into ubuntu. network manager will show a "wifi connected" icon (which is not the whole truth). * open up a console window and type "ping www.ubuntu.com". Nothing will be shown on the console Tested with linux- image-3.4.0-030400-generic_3.4.0-030400.201205210521_amd64.deb. For now, wifi seems to work with this kernel. WORKAROUND: * turn off rfkill switch. Wait until network manager popped up a message saying "wifi disconnected" * turn it on again WORKAROUND: * boot with wifi disabled by the rfkill switch * turn it on only *after* having logged in to your session ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-24-generic 3.2.0-24.37 ProcVersionSignature: Ubuntu 3.2.0-24.37-generic 3.2.14 Uname: Linux 3.2.0-24-generic x86_64 NonfreeKernelModules: nvidia AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
