Without this key, the access point will not contain information on encryption or country-specific radio settings. As a result, the unit will not function correctly.
The following error message will appear: Too many stations in BSS.
Only one client can associate at a time. The Cisco Aironet logo disappears and only the Aironet logo appears in the web browser. Full encryption (128-bit) cannot be enabled. The antenna diversity is not displayed correctly.

To eliminate the chance of deleting the installation key during password recovery, run access point firmware version 11.07 or later, and use the improved password recovery procedure, which is documented here: Resetting to the Default Configuration
