Hi, I was trying to achieve this setup but it failed in LUCI.
It seemed to join the two 5ghz together rather than knowing I wanted to use two radios separately.
Could you clarify what you are trying to achieve? If you want two 5 GHz SSIDs using different channel widths—one at 160 MHz and the other at 80 MHz—this is not supported.
The device has only one 5 GHz radio, so all 5 GHz SSIDs share the same configured channel width. Clients that support only 80 MHz or less can normally still connect when the radio is set to 160 MHz, although some IoT devices with limited Wi-Fi implementations may have compatibility issues.
