AI tells me to :

- Disable MLO (Multi-Link Operation)

- Separate the tri-band SSIDs instead of using the same network name for all bands. Assign each band (2.4GHz, 5GHz, 6GHz) a different name to improve compatibility.

- Turn off Wi-Fi 7 mode or downgrade to Wi-Fi 6 compatibility for devices struggling to connect.

I hope it helps!
