(Optional) Adding client load balancing
In a dual-band SSID configuration, it is best to have most clients using the 5GHz band and leave the 2.4GHz band for clients that do not support 5GHz. Because modern WiFi clients automatically choose the 5GHz band, client load balancing might not be necessary.
If you see that most clients use the 2.4GHz band, you can use the client load balancing's Frequency Handoff method (also known as band-steering). This method helps clients use the 5GHz band if possible.
It is also recommended to use FortiOS 5.6.2 or later because it supports 802.11 k/v/r that newer clients use to select the AP and band.
- Go to WiFi & Switch Controller > FortiAP Profiles and edit the FortiAP profile.
- Set Client Load Balancing to Frequency Handoff for both Radio 1 and Radio 2.
