A:Answer Alexa works off of your wifi signal. So if you install this router properly and have a "wifi" signal, Alexa should work fine. Please be aware that the closer Alexa is to the router, the better it will work. The wifi signal will weaken the further it is away from the router. I had to purchase a wifi extender to get a good enough signal in the rear bedroom to be able to stream TV / movies. Streaming music takes much less bandwidth than video, so Alexa should... work ok.
