We have a router for Xfinity internet, and it works fine EXCEPT it won't reach all areas of the house. I have been using a booster because the Xfinity guys who have come out couldn't get the service to all areas of the house and said they don't do boosters. But now I have a Smart(er) TV in the living room, and both the modem signal and the booster signal do not reach.
Is my only option a second Xfinity router? Or can anyone recommend the best booster to use for this kind of situation?
