We have a main house & a rented guest house 80' apart that share a single Direct TV connection. The guest house tenant uses a separate internet provider since they stream a lot of movies and we use Hughsnet & don't stream a lot. Hughsnet says our biggest user of capacity is from the Direct TV. Is it possible that the wifi from the Hughnet modem is picking up the tenants TV use? If so how can this be resolved?
