Well, I've got it using wifi again yesterday, but now I need to know what the right way to get it to rescan for access points. The wifi hub has once more failed and been restarted, and the laptop seems to have given up on it. '4133' is not in the list of accessible SSIDs, and even though 4133 is up again (other devices have no trouble reaching it), my laptop does not rescan. I seem to remember a time when it would constantly rescan in case something changed (but maybe I have mixed it up with another system).

Re: wifi disappeared completely last night on a Debina Jessie laptop.
I have the same problem. And I resolved it installing wicd. Never trust in network manager :) Il 10.06.2013 06:59 Andrei POPESCU ha scritto: On Lu, 10 iun 13, 04:04:41, Hendrik Boom wrote: I think -- maybe I should ask it to shut down wifi altogether (using the network manager's menu, and then ask it to turn it on again.

For the record, I also have Windows Xp on this system, and booting Windows did not shut off wifi in the BIOS. -- hendrik -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Technically, I suppose the possibility is still there, becaus I could use rfkill. But switching from a menu to a unknown root-level shell command is a terrible user interface. -- hendrik -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
