I would like to know how to optimize roaming between several access points? What are the settings to that make sure a wireless client associates with the AP with the strongest signal as a wireless client traverses a long distance?
You can configure the data rate setting on the AP to maximize coverage area or to optimize on throughput. You can use the Data Rate settings to set the access point/bridge to serve client devices operating at specific data rates. You can also configure the access point/bridge to set the data rates automatically to optimize either range or throughput. For more information have a look at the following URL.
