2 days in a row now, my Ultra TV grid has lost the listings for channels 480-492, and anything above 499. Also through the day, it randomly loses connection with the media gateway, and takes about 3 minutes to reconnect to get my picture back. When I call WOW, they are able to reset the box, and restore the channel grid, but the next day (like today) they are gone again. Anyone else having the quirk?
