A training class has 15 laptops connecting to the WLAN using the same Active Directory training credentials. Users report that they cannot connect until someone else logs off. At any one time, only…

The "Maximum Allowed Clients" setting on an access point or WLAN controller limits the number of devices that can associate simultaneously with a specific WLAN. If this limit is set to approximately half the class size (e.g., 7 or 8 for 15 users), it would explain why only half can connect until someone logs off.

Client exclusion is typically used to prevent specific problematic clients from connecting, not to generally limit the total number of clients for a training class.

Co-channel interference affects Wi-Fi performance and reliability, but it wouldn't directly cause a hard limit on the number of connected clients where users must log off for others to connect.

A DHCP address pool issue might prevent clients from getting an IP address, but it wouldn't inherently cause a situation where half the clients can connect and the other half are blocked until someone disconnects.
