On the FortiGate GUI, the FortiAP may display a 6 GHz radio (R3) status as N/A or Channel 0. To enable the 6 GHz radio with a valid channel, the following debug checks can be done:
- The FortiAP 'PoE Mode' should be 'Full' or 'High', a FortiAP in 'Low' PoE power mode may disable the Radio-3 (6 GHz). Refer to the FortiAP datasheet for the PoE Mode requirements: FortiAP Series.
Note: The 'cw_diag power' command on the FortiAP SSH/CLI will display the PoE Mode of the FortiAP.
-
Ensure the country where the FortiAP is deployed supports 6 GHz frequency for WiFi operations:
To verify whether the FortiAP 6 GHz radio supports 6 GHz channels, use the 'rcfg' command output to display valid channels on the 'hw_chan list' field on the FortiAP CLI as shown below. Also, the Admin should be able to select these 6 GHz channels on the FortiAP profile on the 6 GHz radio in the FortiGate GUI:
The following is a snippet from the output of the 'rcfg' command on a FortiAP-231G deployed in Denmark, managed by FortiGate v7.4.7 GA:
#cw_diag -c radio-cfg
Radio 2: AP
country : cfg=DK oper=DK
countryID : cfg=208 oper=208
802.11d enable : enabled
sta info : 0/0
radio type : 11AX_6G
hw_chan list : 1, 5, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 53, 57, 61, 65, 69, 73, 77, 81, 85, 89, 93,
- Ensure the FortiAP and FortiGate firmware is on the latest 7.4 GA and above versions because the 6 GHz support is enabled for most regions starting FortiOS 7.4.0 and above. Follow the latest FortiAP and FortiOS Compatibility Matrix:
FortiAP.
- The 6 GHz supports only WPA3 SSIDs (WPA3-Enterprise, for example), and the Radio-3 (6 GHz) will display a valid operating channel only when WPA3 SSID is mapped to the radio in the FortiAP profile:
