[Bug 1366423] [NEW] My wifi connection is unstable. It disconnects every few minutes. Sometime it will reconnect on its own and at other times I have to manually reconnect. I have Windows 8.1 running on a different partition in the same machine. Wifi works fine in Windows 8.1. So, this seems to be an issue with Ubuntu.
