Client Load Balancing by Central AP Management

Published On: Oct 16, 2015 

Deploying more AP on the network to share the traffic load will bring better Wi-Fi performance, but we don't want all the client connecting to only one AP. AP Load Balance could be the solution to one AP gettings overloaded while others are still free.

AP Load Balance can be set up with Central AP Management (APM) on Vigor Router. AP can achieve Load Balancing by rejecting a new station when it already has too many or too much traffic, thus force the new station to connect to other free AP. To enable AP Load Balance, please go to Central AP Management >> Load Balance on Vigor Router.

Balancing Stations Number

With “By Station Number” enabled, every AP has a limit of station number allowed. When the number reaches, the AP will not rejects new connections, so the new station must connect to other less crowded AP.

This is the same as Client Limit settings on VigorAP. In fact, when “By Station Number” is enabled, the Limit Client on VigorAP will be set to the same number.

Balancing Traffic

With “By Traffic” enabled, every AP has a limit for upload and download traffic. When the AP reaches the limit, it will stop allowing new connections, and make the new station connect to other less busy AP.

These two options can enable at the same time, VigorAP will stop accepting new connections when it meets one of the conditions.

Disconnect existing stations for new connection

While using AP Load Balance, we can also enable “Force Overload Disassociation,” which allows the AP to disconnect one of its existing stations when there is a new connection request while and it reaches the limit.

Disassociate idle stations

If “Force Overload Disassociation by Idle Time” is enabled, when the AP is full and there is a new connection request, AP will end the connection with the station which idles the longest, and then accept the new connection.
Only the station that has neither TX nor RX traffic over one minute will be regarded as idle. If there are no idle stations, AP will reject the new connection.

Disassociate the stations with the weakest signal

With “Force Overload Disassociation by Signal Strength” enabled, when the AP full and there is a new connection request, it will end the connection with the station which has the lowest RSSI and then accepts the new connection. But if the new station has a lower RSSI then all the connected station, it will not be allowed to connect.
