Had pretty good initial success with them but I am starting to see issues where one of the APs will just check out. It still shows up in the controller utility and still has an IP address but it just stops transmitting. Power cycling the offending WAP will bring it back up and it will stay up for weeks/months at a time.
Have experienced this with two different systems so far. One was with 3 310 waps, the other with 2 1210s.
I am a trained professional..... Do not attempt this stunt at home.
