Does anyone who has Comcast/Xfinity have problems with their wifi staying connected while trying to use Apple TV? Every day we have the same problem of getting kicked off of wifi while trying to stream anything. We'll pick a TV show to stream from Itunes or HBO Go and either get a message that we are not connected to wifi or the show will play in 45 minutes - 2 hours. We contact Comcast (every night) and they tell us to unplug the router and Apple TV box and replug it back in, which seems to help for a little while but the problem comes right back the next day. Any suggestions? Comcast is the only provider we have available to us, so switching providers is not an option, unfortunately. Thanks!
