    It works, but has to be near another wi-fi monitor to work and be strong for wi-fi services to work. I just need to purchase a cable to connect it.

    The product was in good condition, but I didn't do my homework. They are not compatible with my new ATT router, so they are useless to me.

    The product is not compatible anymore with the new ATT routers.

    This is the best way to beef up your AT&T internet signal

    This is what AT&T recommends to make our Internet signal if you have AT&T internet.
