ASUS GS-BE18000 AFC Quirk

[VidMan]

Until recently, I had a combined 5GHz/6GHz SSID where despite AFC indicating it was on, the 6GHz signal strength was always 6-10dBm less than the 5GHz signal. Now, after I split the 5GHz and 6GHz signals into separate SSIDs, the 6GHz signal strength has increased and is matched with the 5GHz signal strength, which is more in line with AFC that is now properly working. So, just a heads up that there may be a glitch in the current firmware from December 2025 where AFC may not actually be working despite indicated otherwise if using a single SSID that combines 6GHz with any other frequencies.
