Bought this router in hopes of getting better coverage in our house AND to give my wife control over the kids' internet use. All I can say is YESSS! It worked perfectly for both. The 5G stream to our tlelvision has ended some of the lag we had with our service provider's WiFi router. The Genie app has worked great for my non-technically inclined wife. Kids hate that our internet service now has so many 'interruptions' ;).
This is the best router we have owned! It has the easiest setup and superb connectivity of any previous devices! We have up to 5-7 devices at a time without any issues.
I attached the router to my supplied router from my internet provider and it greatly added speed and range! It also helped with disconnects and having to reset the router from my provider. I highly recommend this for a family of four.
