Bug Description

This began when I upgraded to Ubuntu 15.04. My workplace is in a place in which the wifi signal from my network is weak. So, sometimes, it loses the signal. A quick solution that sometimes works is turning (either through hardware or gui) the wifi off and back on again. However, it seems that when I do it a couple of times, no network will be detected anymore (not even my neighbor's, which is strong here). Rebooting will turn things back to normal.
