Hi, I've just gotten the tab and the home wifi is connected and shows strong signal, it would work for a while and then the internet would stop working and pages won't load. If I disconnect and reconnect, it would work for a while and then would stop working again. I've tried with the galaxy tab 10 and the same thing happens and this one seems to work longer before stopping. Samsung web support didn't help much and just asked me to return the devices for diagnostics. Can someone help?
