I have recently upgraded to 16.04.1. This problem did not begin immediately after upgrading, rather it showed up quite a few weeks after upgrading. The issue is that the wifi connection to any network keeps getting disconnected at random. Moreover, wifi is very slow to connect to a network to begin with. After getting interrupted, it is very difficult to connect to a network again. I've browsed through MANY threads with a similar problem, but no proposed solution seems to work. Any help would be appreciated. I am a newbie on Linux, so please suggest edits and any required details.
Result of 'lspci -knn | grep Net -A2' terminal command:
