10.4.1 Disassociating and Delaying Connections
When your AP becomes overloaded, there are two basic responses it can take. The first one is to
“delay” a client connection. This means that the AP withholds the connection until the data transfer
throughput is lowered or the client connection is picked up by another AP. If the client is picked up by
another AP then the original AP cannot resume the connection.
For example, here the AP has a balanced bandwidth allotment of 6 Mbps. If laptop R connects and it
pushes the AP over its allotment, say to 7 Mbps, then the AP delays the red laptop’s connection until it
can afford the bandwidth or the laptop is picked up by a different AP with bandwidth to spare.

The second response your AP can take is to disassociate with clients that are pushing it over its balanced
Disassociate
station when
overloaded
This function is enabled by default and the disassociation priority is always Signal Strength
when you set Mode to By Smart Classroom.
Select this option to disassociate wireless clients connected to the AP when it becomes
overloaded. If you do not enable this option, then the AP simply delays the connection until
it can afford the bandwidth it requires, or it transfers the connection to another AP within its
broadcast radius.
The disassociation priority is determined automatically by the Zyxel Device and is as follows:
• Idle Timeout - Devices that have been idle the longest will be kicked first. If none of the
connected devices are idle, then the priority shifts to Signal Strength.
• Signal Strength - Devices with the weakest signal strength will be kicked first.
Note: If you enable this function, you should ensure that there are multiple APs
within the broadcast radius that can accept any rejected or kicked
wireless clients; otherwise, a wireless client attempting to connect to an
overloaded AP will be disassociated permanently and never be allowed to
connect.
