Chapter 6 Wireless

NWA5000 / WAC6500 Series User’s Guide

Each field is described in the following table.  

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.

Configuration > Wireless > Load Balancing

Enable Load 
Balancing

Select this to enable load balancing on the NWA/WAC.

Use this section to configure wireless network traffic load balancing between the 
managd APs in this group.

Mode

Select a mode by which load balancing is carried out.

Select By Station Number to balance network traffic based on the number of specified 
stations connected to the NWA/WAC.

Select By Traffic Level to balance network traffic based on the volume generated by 
the stations connected to the NWA/WAC.

Select By Smart Classroom to balance network traffic based on the number of 
specified stations connected to the NWA/WAC. The NWA/WAC ignores association 
request and authentication request packets from any new station when the maximum 
number of stations is reached.

If you select By Station Number or By Traffic Level, once the threshold is crossed 
(either the maximum station numbers or with network traffic), the NWA/WAC delays 
association request and authentication request packets from any new station that 
attempts to make a connection. This allows the station to automatically attempt to 
connect to another, less burdened AP if one is available.

Max Station 

Number

Enter the threshold number of stations at which the NWA/WAC begins load balancing its 
connections.

Traffic Level

Select the threshold traffic level at which the NWA/WAC begins load balancing its 
connections (Low, Medium, High).

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 NWA/WAC 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.
