I was having troubles with Netflix freezing up....sometimes twice a night. I was a bit sceptical that these would work. I checked that the modem and smart TV were on the same circuit and plugged them in. It was amazing the difference it made as the picture in normal HD was crystal clear and in.UHD was as good as you see in the stores with those demo videos. To top it all off Netflix has never frozen since.

Bought a cheap tv and connection to Wi-Fi w as driving me crazy. Bought this and plugged it to the back of the tv and into the power and no more problems. Never seen a buffering circle since. Very happy
