STATUS_NDIS_DOT11_MEDIA_IN_USE
The WLAN miniport cannot accept the request while its radio/media path is busy
STATUS_NDIS_DOT11_MEDIA_IN_USE is a transient Native 802.11 state failure. The adapter may be scanning, associating, authenticating, changing operation mode, serving as an AP, or completing another exclusive radio operation. The media is not necessarily broken; it is occupied by another operation.
Diagnose the owner of the current radio activity. A management command that is safe while disconnected may fail during association or AP startup. For drivers and tools, serialize operations around operation-mode changes and asynchronous indications rather than assuming every OID can be issued at any time.
Evidence that narrows it
- Capture the current Native 802.11 operation mode and pending wireless operation.
- Check whether scanning, association, roaming, hosted-network, or AP startup is active.
- Retry only after the conflicting operation completes; repeated immediate retries can keep the interface busy.
