I have set up my A3 as a mesh network all units wired, all of that was easy. Originally purchased these because the cable modem's wifi broadcast was weak on the second floor. While the signal from the A3 shows strong, there is not actual improvement in quality/connectivity.
When I look at the main A3 from the browser or the iPad app I always see the secondary unit as inactive. Is this normal? I am asking because the secondary unit is set up on the second floor within line of site of a Macbook Air that is only wifi connected and the connection is intermittent. The primary unit is on the main floor.
