Comment 70 for bug 1349572

On my Dell Inspiron 7537 the wifi is working very well on 3.16 (trusty), however I experience frequent disconnections on 3.19 kernel (vivid). After I get disconnected, no APs are visible by Unity wifi applet. However, using wavemon to connect to a network "fixes" everything for about 1 hour. Switching off wifi power saving helps. I'm wondering why everything works well on the 3.16 but I have issues on 3.19.
