After hours of trying to connect extender and help of the technician, I decided to return. The WiFi had not changed from 1 bar on my devices.

I had difficulty establishing the network connection. The specialist worked through it with me until completion. The first specialist was terrible and rude, but the second one was great.
I have a Gig of internet speed, but this extender top speed so far is 70Mbps is not the greatest but I have a Xfinity pod and top speed on that one has been 200Mbps. The EX6250 does it job not many devices connected to it, so it’s solid when I have my Xbox connected directly to it. Overall is a good extender for the price!
The setup of the router was a little weird - no real instructions included in the box, but I muddled my way through it. Ever since then, it has worked flawlessly.
