Xi5-p signal cuts out

Received new xi5-p box because our old xg2v2-p box would randomly lose signal. The signal loss would be anywhere from 1 second to 10 seconds. Hook the new xi5-p up and it’s doing the same thing. The old box connected via a cable line and the new box is wireless. I’m totally at a loss and frustrated to say the least. I’m forced to watch playoff hockey through my Roku. 😀
