Tablo - HELP! Not working the way it should

I have my Tablo (TF1282B-01-CN) connected to a Phillips Tv which uses a ROKU format. I have a outdoor antenna hooked up to the tablo and run a ethernet cable to my router. After I do a rescan of channels, the guide doesn’t show all the channels that were found. Also tablo keeps jumping back to the roku home screen. I also have my router connected to a switch which has a ethernet cable going to my tv in the livingroom. Tablo doesn’t work on that tv, all I get is a spinning circle on the screen.
