MF_E_NET_COMPANION_DRIVER_DISCONNECT
MF_E_NET_COMPANION_DRIVER_DISCONNECT means a companion driver requested a receiver disconnect. This is generally a device or transport-stack event, not an ordinary origin-server error.
What to check
- Check device, Wi-Fi Display, network adapter, and driver event logs at the failure time.
- Verify driver and firmware compatibility for the receiver and source devices.
- Reproduce with the same media path only after confirming that the device connection remains stable.
