airMAX - How to Connect airMAX M Stations to an airMAX AC Access Point


Users will learn how to connect airMAX M Stations to an airMAX AC Access Point. 

Applicable to firmware airOS8+ (airMAX AC devices) and airOS 6+ (M devices). Note that airMAX Mixed Mode is only supported with the airMAX AC radios as the Access Point. An airMAX AC Station cannot be connected to an airMAX M device if the latter is in Access Point mode.

Be sure to go through this checklist and verify each item:

  • SSID and WPA2-AES values on both radios.
  • Channel width.
  • Disable any frequency lists and confirm the Station supports the AP operating frequency.
  • Due to the number of channels available in the 5GHz band, it can sometimes take several minutes for a radio to connect. Especially if the AP is using a DFS frequency that requires a wait time before transmitting.
  • Confirm radios are on firmware that supports mixed mode operation: airOS 8+ for AC devices and airOS 6+ for M devices.
