When I hibernated my computer and I fire him back up, my network connection is lost in about 50% of the cases. The network applet finds other networks, but it can't find the network I was connected to before the hibernate.
I have this most of the time with a wired connection but it also happens with a wireless connection.
I've tried re-plugging the cable (or switching off and on the wireless card), disabling the network via the network applet and re-enable it. The only thing that works is the following:
- log out
- log in back again
- disable all networks
- enable them again
