Dissociate station when | Select Enable to “kick” connections to the AP when it becomes |
overloaded | overloaded. If you set this option to Disable, then the AP |
| simply delays the connection until it can afford the bandwidth |
| it requires, or it shunts the connection to another AP within its |
| broadcast radius. |
| The kick 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 NWA will be kicked |
| continuously and never be allowed to connect. |

21.2.1 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 the red laptop (R) attempts to connect and it could potentially push the AP over its allotment, say to 7 Mbps, then the AP delays the red laptop’s connection until it
