There'sno specific wifi button on my Asus 1000HE. There's just the network manager's menu (which is part of Debian, not part of the hardware) and the switch in the BIOS, which I'll consider hardware (technically, though I suppose it's firmware). Now that I know how to turn it on again, I'll try and see what rfkill says sometime. -- hendrik > > Greetings, > > -- > Camaleón -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
