I have Ubuntu 14.04 LTS and Lenovo Thinkpad Edge E430. I have great problems with some networks. Some networks work fine, like my Android hotspot, but unfortunately among the networks with problems are my home network and school network.
The problems:
- Trying to connect lasts very long, is mostly unsuccessful, showing "Disconnected: network" or "Disconnected: ". Sometimes I need to restart Wireless, sometimes entire Networking, sometimes I even need to reboot the system to make it connect.
- When connected, after a while (sometimes hours, sometimes 10 sec) all communication stops. ping 192.168.1.1 unsuccessful, ping google.com unknown host. When this happens, I have to manually disconnect and reconnect, where I often crash into the first problem and in the end I have to reboot.
This is very, very frustrating. This problem was there and gone and back for a long time, over several Ubuntu versions, but now it is very present and causes a lot of trouble. Lenovo offers no wifi driver for Ubuntu. Could this be because I dropped my laptop a year back in its bag, when the shoulder strap broke?
What should I try? Thanks.
