I was having trouble receiving WiFi signal in my bedroom. It was sporadic and weak. Netflix was almost impossible to watch because of buffering and poor picture quality. After looking at several WiFi boosters I purchased this one. It was simple to set up (5 minutes) and directions were easy to follow. I am truly amazed at the signal improvement. No buffering whatsoever and picture is no longer poor quality. My iPad works again in this area of the house.Thanks to Wavlink.
