I have an old house that has the old Coax cable installed for our TV’s opposed to the new CAT5. Instead of rewiring my house our TV cable provider said I could use a powerline adapter, such as, NetGear Powerline 200 mini or TP-Link AV500 Nano. I would need one for each TV, which I have 3 on three different floors, and another connected to the primary cable box (4 total same model), which is also plugged into and electrical outlet. Both models worked for a while and then we started having problems with the TV’s getting really fuzzy or losing the signal altogether. We can unplug the main powerline adapter connected to the cable box wait a few seconds and re-plug it back into the wall and everything is fine again; however, an hour or a day later we experience the same problem. Does anyone know how to resolve this issue or is there is a different powerline adapter that would fix this problem? Recabling my house with CAT5 is NOT an option. Thank you.
