A:AnswerI use all 3 of my Netgear nighthawk extenders on my ASUS router, they are compatible with any brand as far as I know, works great too, wired and wirelessly
A:AnswerYou have to have internet service I. Order to get any kind of WiFi. The extender just lets you extend your existing internet so it with reach further than your router does. No provider, no internet, no wifi
A:AnswerBoth my brother and I purchased the Netgear EX7000 to help with the signal in our RV park. It has worked very well extending the signal and strength.
A:AnswerShould work with any router as long as it has a WPS button to sync with the device. If your router does not have that, I recommend looking up this device's manual online to see if there are alternative syncing options.
A:AnswerI used it for two weeks with the same AT&T modem you mentioned. It worked, but it would occasionally desync or drop signal, and after a week it would not register the 5GHZ signal.
A:AnswerYes that is who I have service with ATT unverse.
It is working great. Increases my up stairs signal to a max signal. I highly recommend thi item.
