However, I wouldn't recommend designing a wireless network to these limits, it almost certainly won't work as you expect. I'd probably aim for between 20 and 30 clients per AP, but that depends on the likely clients types, traffic flows and the environment.
We have a large training room that might have 20-30 fellows in there occasionally. A few will complain that they could not get onto the wi-fi. I am just wondering if their was a licensing limit or is it time to install another WAP in there.
Nope, no licensing limit on the number of clients, so it may be time to install a new AP. Have a look in the dashboard at the wireless performance info and see if you can determine why they're not able to connect, check the number of clients connected to the AP to see if its high, and don't forget to have a look at the event log for the network too.
