When I am connected to wifi I notice I loose data after about 10 minutes of inactivity. The phone still says its connected but the router says that is not. I also noticed it doing it with my Xoom also. I looked through all the settings thinking it is just a setting to see power but all the power savings options are turned off. I also thought it was my router but other devices dont do this and it does it on other routers. Any thoughts?
