Customer Reviews:
Bought these in the hope of eliminating dead spots and weak wifi reception. I own a three floor home, and the modem is in the basement. Installation was simple and easy, which includes the update. It took 5 minutes to upload and setup… it does it for you. After installing the three units, one on each floor and try to center them visa-vie each floor, so the spread is raven throughout the floor. Once everything was setup, what can I say. It’s a life saver. It eliminated all my issues. Signal floor to floor was full bars with no lagging, wavering or delays in catching wifi signal. Why buy more expensive mesh units were this does the job at a fraction of the cost and IT WORKS FLAULESSLY! Thanks to the folks at TP-Link for developing a system that is affordable and does more than what you want. Look at the app and you will be amazed.
