What is AP Load Balance?

When there are more than one access point(AP) in the network, network administrator may set up APLoad Balance to prevent that one of the AP gets overloaded, while others are still quite free.This help improve the Wi-Fi performance for all the wireless clients.

AP Load Balance can be set up with Central AP Management (APM) on Vigor Router. Load Balancing is achieved by disallow new connections to the AP when it already has too many stationsconnected 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 between APs

With “By Station Number” enabled, every AP has a limit for station number. When the station number of one AP reaches the limit, that AP will not allow new connections; thus, the new station must connect to other less crowded AP.

   

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

   

 

 

 

Balancing traffic between APs

With “By Traffic” enabled, every AP has a limit for upload and download traffic. When the traffic of one AP reaches the limit, that AP will not allow new connections; thus the new station must connect to other less busy AP.

   

These two modes can be enabled at the same time, and VigorAP will disallow new connections when it meets one of the conditions.

 

 

Disconnect stations for new connection

While using AP Load Balance, network administrator may also enable “Force Overload Disassociation”, which allows AP to disconnect an inactive station, or the station with weakest signal strength, when there is a new connection request while AP is overloaded.

Disassociate idle stations

With “Force Overload Disassociation by Idle Time” enabled, when the AP is overloaded and there is a new connection request, AP will end the connection with the station which idle the longest,and then be available for new connection.

   

Note: only the station that has neither TX nor RX traffic over one minute will be regarded as idle, if there are no idle stations, new station will not be able to connect.

Disassociate the stations with the weakest signal

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