in SSID
Scenario
After enabling Multi-Link Operation (MLO), certain devices cannot connect to my 2.4GHz/5GHz/6GHz SSID. Disabling MLO resolves the connectivity issue.
Root cause
When an SSID with MLO is enabled on 6GHz, the SSID security is automatically converted to WPA3-related settings as per specifications. Some devices, especially IoT devices, that don't support WPA3-related settings cannot connect to this SSID.
Solution
Create a new SSID with suitable security settings for IoT and other devices that don't support WPA3.
