A:Answer I have my AC1900 installed on the second floor of our 2,800 sq. ft. house and it covers that as well as a 100 foot radius around the house. I have a small signal booster installed in the master bath at the far end of the house due to a reduced signal in that area due to electrical and piping interference. I have a total of 18 devices connected to it including: A SONY XBR TV, and an eight speaker Yamaha wireless MusicCast system, 2 computers, two tablets, two Amazon Echo Dots, an Alexa speaker and two phones. I have never has an issue handling all of these although, obviously, not all are in operation at any given time.
