A:Answer You might have 25mb/s at your router but the TV might be picking less than that. Use the Silk browser and navigate to speedtest.net, fast.com or speedtest.xfinity.com to see check the tv’s bandwidth. Your tv’s distance from the router, wifi connection and type of cable matter. If you use wifi bring the tv closer to the router and use 5ghz wifi, and get a faster router, if hardwired get a better quality cable. But 5gz wifi can be faster than hardwired ethernet if the tv is close to the router and you have a fast router.
