Start by reproducing the mt7612 5G station-plus-AP setup and inspect the reported hostapd errors, especially the HT/VHT/HE channel-setting and DFS messages. Determine which configuration or driver path prevents the AP from appearing; done means the AP is visible and the logged failures no longer occur.
