A:Answer Hello, and a happy new year to you :)
I wonder if the TV is getting a lot of interference from electronic items around you or in other rooms. I imagine you have tried this already, but if not, try moving the antenna in as many different positions as possible, until you find one that will bring the stations in better or get rid or clear up, the fuzziness.
I don't have WiFi either, and most of the free stations come in very clear...but, sometimes I have to move my TV antenna to a different position, to bring certain far away stations in.
If my suggestion does not help, if you can, try buying another TV antenna, preferably, one that will pull in very far TV signal's. I hope this helps you. Have a good day.
