After reinstalling Ubuntu 13.04 Desktop on my Lenovo ThinkPad Edge e320, I got a problem with my network-card (may be because I also have openSUSE and this has the same problem). I have Intel Corporation Centrino Wireless-N 1000.
The problem. After using the WiFi-network for about 15 minutes it just switches off. I still can see the connection on the Network-Manager, but I can not load any website or ping.
service networking restartdoes not help.
- Just switching off the currently connection and switching it on again sometimes works,
- rebooting, too.
But I have no idea, how to get the WiFi network working stably again.
Can you help please?
