    Good price and very easy setup. I used the app to set it up and, surprise, no problems at all LOL

    I was pretty skeptical of the effectiveness of the device due to the low price compared to the competition. Turns out those were unfounded! The directions in the quick start guide are clear and had the device set up in two minutes with the push of two buttons; no connection to a computer was necessary since my router had WPS.
    Our router is on the first floor in the office (far east side of the house). I took the extender to the west side basement to test it out. [Test was quickly done using a Samsung Galaxy S3 on Verizon, used the wireless network settings menu to view signal strength and link speed]

    This works pretty good. I used it for my outside mounted Arlo cameras. The base station was in the house and the signal was very weak on each camera. I connected the tp link and my problem has been solved. Setup was a breeze. It uses your current wifi name so that you do not have to get on a computer to configure extra settings. I plugged the range extender into an outlet in my unattached garage and it still picked up a good signal from my inside router.

    Really happy with this product! We used to be completely unable to get good signal in our bedroom, the farthest room from the router.
    Now, be can both stream videos on your phone, side-by-side with no problem! definitely recommended

    Just amazing, I have a small apartment in the Czech Republic, but, somehow, my wifi signal couldn’t seem to reach from my bedroom out to the living room! Enter the TP-Link Range Extender. Not only do I now get a strong signal in my living room, but I can even connect to my home wifi from almost a block away! Works even better than I expected.
