STREAMING SHOWS WITH CONSTANT FREEZING

Since changing to Xfinity streaming, while watching movies on Disney, Hulu, etc. there are frequent pauses or "loss of internet connection” notices. I have the fastest internet speed Xfinity offers (932.9 and 39.2 Mb/s), a HP Envoy TE01-5364 desktop computer with Windows 11, Nighthawk Model #CAX30 router, Samsung smart tv's that are withing 33 feet of the router. I rebooted everything and it still happens, especially in the late afternoon and evening.
