7.4.1 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.
Figure 38 Delaying a Connection
The second response your AP can take is to kick the connections that are pushing it over its
balanced bandwidth allotment.

DESCRIPTION
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 NWA 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.
