Hello user_1fe22f 👋 Thanks for taking the time to reach out in our community with your post! I definitely know how annoying it can be to deal with pixelation when I'm trying to watch TV, so I want to help however we can. Typically, your gateway should not be impacting the signal your TV is able to pull in for its channels, but when both are feeding off signal from the same coaxial outlet, this can change. To confirm, are you saying that you've tried multiple splitters on the outlet in your home and neither of them are providing any signal for you when you do?
