ASUS RT‑AX3000S advertises per‑band controls in the Professional settings, but several options are actually global toggles. Airtime Fairness, MU‑MIMO, and Xtra Range 2.0 all change on both bands no matter where you set them. The UI makes it look like these are independent 2.4 GHz and 5 GHz settings, but the firmware doesn’t behave that way. This is misleading and causes unintended configuration changes, especially for users who tune each band differently. ASUS should fix the UI or implement true per‑band control. If a setting is global, don’t present it as per‑band. Professional mode should behave professionally.
