Miniport drivers use NDIS_STATUS_WDI_INDICATION_LINK_STATE_CHANGE to indicate any of the following situations:

  • The link speed changed.
  • The link quality changed by more than a threshold value. The threshold is 1 if the connection quality hint is set to WDI_CONNECTION_QUALITY_LOW_LATENCY (defined in WDI_CONNECTION_QUALITY_HINT). Otherwise, the threshold is 5.
