Any of you guys experiencing wifi issues after the update? I just noticed after I did the update yesterday my wifi signal became more unstable. I am siting within 6-7 feet from the router and signal bars are jumping from 4( full) to 3. Practically sitting on that damn router. Before update it was solid full bars no jumping issues. Now I regret that I updated the device. Hope 3.1 will fix it. I thought this update should fix wifi issues that some people had, not make it worse?
