"Failed to start driver for port awc0" error message appears on the access point (AP) - due to a corrupt image

Core Issue

The Failed to start driver for port "awc0" message appears after upgrading the firmware on the AP. The radio firmware might be corrupted.

Resolution

If you update the firmware and remove power before the unit finishes the start-up sequence, the radio firmware might be corrupted, making the unit inoperable.

If the radio firmware is corrupted, the radio indicator (the bottom of the three indicators on top of the access point or bridge) lights steady red, and this error message will appear on the access point or bridge.

If the radio firmware is corrupted, you should try to reset the unit to factory defaults using the resetall command in the CLI.

If the unit cannot be reset to defaults, return the unit to Cisco for service by opening a case with the Cisco Technical Assistance Center (TAC).
