I have this to help with WiFi in the basement and does a good job so far.
I extended my network from the garage to our gate for the wifi controller.
The router is inside the garage and about 35 feet from the gate, and the other router it is extending is about 105 feet and behind 2 walls and a cabinet door, so it was worth the $ in my opinion.
Works simply, sets up easily.
I have been using this extender for a couple months now and it hasn't had any issues.
The problem arrived when I had to upgrade my Comcast equipment to a higher tier, so I attempted to log into the extender to apply the new modem wifi login with new password and settings to no avail.
Tried to connect using ethernet still nothing happened.
Had a good showing on meter but devices did not perform well with it.
Part of the problem was the layout of my home and device locations as related to where extender was placed.
May perform well in a different setup.
