I have a 4404 with 50 1142 access points, and I want to know if there is a limitation to the amount of concurrent associations per SSID?
Im not aware of any specific limitations to the amount of clients per SSID. We have over 3000 on one SSID without any issues.
You do have limitations to the amount of SSIDs you can have (16). And you want to limit the amount of clients per AP. Meaning you dont want 20+ clients per AP all using heavy data/voip for obvious reasons ...
