Efficient method to load-balance wireless networks with multi-band interface controllers

A dual-band access system, comprising:

• a dual-band radio including first and second access points (APs);
• a memory;
• and
• a processor configured to:
• receive a first probe request from a client device over the first AP operating at a first frequency range of a wireless network;
• establish a first association between the first AP and the client device;
• send a transition request over the first AP, responsive to determining that the first association is with the first AP, to instruct the client device to transition to the second AP operating at a second frequency range of the wireless network, wherein the second AP a default AP of the dual-band radio and has a bandwidth that is different from a bandwidth of the first AP;
• and
• establish a second association between the second AP and the client device.

A system comprising:

• a base station comprising a first dual-band radio and a processor;
• and
• a client device comprising a second dual-band radio, wherein the client device is to:
• send a first probe request at a first frequency range of the first dual-band radio;
• establish a first association with a first access point (AP) of the base station, wherein the first AP corresponds to the first frequency range;
• and
• send a second probe request at a second frequency range of the first dual-band radio;
• and wherein the processor is to:
• responsive to determining that the first association is with the first AP, send a transition request to the client device over the first AP, wherein the transition request comprises instruction for the client device to transition to a second AP of the base station, wherein the second AP corresponds to the second frequency range, and wherein the second AP is a default AP of the base station and have a bandwidth that is different from a bandwidth of the first AP;
• and
• establish a second association with the second AP.
