airMAX - Station won't connect to Access Point

Problem


Station radio will not connect to airMAX AP.

Possible causes / recommended actions


  • Compatibility between radios.

    Frequency: Radios must use same frequency range. As an example, M5 and M2 products are not compatible.

    airMAX Protocol: Any airMAX AP with the airMAX protocol active will not allow connections from Stations that are not airMAX-ready. To connect non-airMAX clients, disable the airMAX protocol on the AP. Note that disabling airMAX is not recommended since airMAX provides the best possible performance in outdoor wireless networks.

    airMAX-AC: airMAX-M devices are only able to connect to airMAX-AC Access Points.

  • Compatibility between Legacy station and airMAX AP.
    1. Upgrade Legacy station to version 4.x.
    2. Upgrade airMAX AP version 6.x.
    3. Now Legacy radios (e.g., Bullet, NanoStation) can connect to AP with airMAX enabled.
    4. Navigate to airMAX AP GUI.
    5. Make sure that airSelect is not enabled.
  • Compatibility between non-Ubiquiti radios and airMAX AP.

    1. Navigate to airMAX AP GUI.
    2. Navigate to airMAX tab.
    3. Disable airMAX protocol on airMAX
    4. Click "Change" then "Apply."
    5. Now the airMAX AP will use the 802.11 CSMA / CA protocol to work with other stations.
    6. Navigate to Wireless page and ensure that channel shifting is disabled.
  • Misconfiguration on AP or Station.

    1. Navigate to Wireless page.
    2. Check that wireless settings match on AP and Station, including:
      > SSID
      > Channel widths (e.g., AP = 40MHz & Station = 40 / 20MHz).
      > Operating frequencies
      > Channel shifting
      > Wireless security
  • Misconfiguration on AP or Station.

    1. Navigate to Wireless pages of both AP and Station.
    2. Check that wireless settings match on AP and Station, including:
      > SSID
      > Channel widths (e.g., AP = 40MHz & Station = 40 / 20MHz).
      > Operating frequencies
      > Channel shifting
