Troubleshooting Tip: Use both 2.4 GHz and 5 GHz Wifi at the same time on FortiWifi

[vbandha]

Description	This article describes how to check if it is possible to use both 2.4 GHz and 5 GHz WIFI at the same time on a FortiWifi model.
Scope	FortiWifi.
Solution	To use both 2.4 GHz and 5 GHz WIFI on FortiWifi, it is necessary to have at least two radios on the FortiWifi model. So whether this setup will work depends on which FortiWifi model. It is possible to get the Wireless Interface details from the datasheet of the specific FortiWifi model. For example, check the datasheet of FortiWifi 40F: FortiGate FortiWiFi 40F Series It lists the ‘Wireless Interface’ as ‘Single radio’, so this model cannot support both 2.4 GHz and 5 GHz wifi at the same time. Check the datasheet for FortiWifi 80F: FortiGate FortiWiFi 80F Series It lists ‘Wireless Interface’ as ‘Dual Wifi Radio’, so this model can support both 2.4 GHz and 5 GHz at the same time.
