Ha!! Knew it!! Or strongly guessed it. I have a Sonly Blu-Ray player and Netflix has become a stuttering piece of crap when I stream to it. But Amazon Prime streams just fine. On my PCs it’ll just drop from HD to standard video. 
Curious if anyone’s done tests with their routers. My phone can connect to any WiFi hotspot & get webpages fairly quick. At home it becomes painfully slow. But my PCs chug along like champs on the WiFi router from Verizon. Truly, I believe they’re doing something with their router. Like they’re trying to get me to pay for Quantum because they play games with the net & the router.
