This just started recently, it's worked really well since Ive had it ( about a year now). Same TV ( Samsung). The router and modem are close to the TV Any thoughts as to why this might be happening.
Buffering is typically a connection issue. Have you tried restarting the modem on the account?
I unplugged it and the router....waited a few minutes then plugged it back in. No change...):
Are you able to post the results of a speed test and modem signal levels?
