I am using Ubuntu Trusty Tahr (14.04). I have my WIFI driver installed properly. When my computer starts, and if an Access Point is saved, it will connect to it. It works fine for 5 miutes or so before it stops working (WIFI AP stays connected but does not connect to the internet). And then if I disconnect from the WIFI and connect again, it won't connect at all. So WIFI APs only get connected on startup and stop working after a few minutes.
Can anyone help me on this?
