ubuntu 10.10 network icon disappearing overnight and losing wireless connection.

Posted on August 19, 2011

I started having this problem a couple of days ago, my work laptop (usually on 24/7)would lose its network connections in ubuntu 10.10 overnight, however, any virtualbox machines would still keep whatever (wired) connection they were using. this has been happening the last two nights for some reason.

anyway, after checking various logs, i came across the "cfg80211: All devices are disconnected, going to restore regulatory settings" error, and googling brought me to http://azitech.wordpress.com/2010/02/22/deauthenticating-reason3/

All the posts helped, but after killing the single instance of wpa_supplicant, it still wasnt working.

in my case, the network-manager applet icon had also disappeared from my menubar. after running "nm-applet" my connections all came back to life. job done!

brilliant! trashing a maybach, doing doughnuts in it, scaring the bitches in the back, then a completely random cameo from aziz ansari before getting the pyrotechnics out.
