Sony Tablet S Recently bought - upgrade recently installed First day wifi worked with no problem. Don't have a gmail account so wasn't able to set that information in the tablet. Next day wifi is connected but gray in color when on the first day it was blue in color (even after the upgrade). Only app installed was Angry Birds Star Wars I have seen in other forums where the router may be b/n/g and should be set to n/g. I have seen in other forums where the router may have all channels open and should be limited to for example 10. I can't connect to internet or Google play. Any suggestions?
