Connect your TV by Ethernet cable (Cat-6 or better) directly from your internet router. I don't need 1ghz speed as 400 MHz is plenty, and being directly connected takes all the connection issues out of scope. When my son and I first moved in, I had them check the existing cables as I was having connection issues (intermittent connectivity) and it turned out there were old splitters in the walls that were causing issues. Many streaming issues have more to do with your internet signal strength than the actual provider. I run a 100 foot flat cable to my desktop computer now, and it works great. Ditto for my TVs. Amazon sells cat-6 cables cheap.
