Is there some kind of cure for this? My router is fine, everything here is working, but when I wake up my Nexus and go to Gmail or the Play store or Breaking News, I get this message all the time. I bang at the "refresh" symbol once or twice more in the app, and it eventually "catches".
Any way you can get this to work correctly the first time more often? I'm never more than 25 feet from the wifi router at any time!
