What does NTSTATUS 0xC022003E (STATUS_FWP_L2_DRIVER_NOT_READY) mean?

STATUS_FWP_L2_DRIVER_NOT_READY

WFP layer-two filtering is not ready yet

Some WFP layers operate at MAC or layer-two boundaries. This status means that part of the stack is not ready when a filter, callout, or injection operation is attempted.

Check the Layer-2 callout or driver readiness that the operation depends on, together with BFE state and adapter initialization. Replaying the request before the L2 provider is ready will produce the same result.

What to inspect

• Retry after network adapter and NDIS initialization.
• Check whether the operation targets MAC layers too early in boot or resume.
• Correlate with adapter arrival, miniport state, and binding changes.
