Problem Description

The installation key of the access point has been inadvertently deleted either during a firmware upgrade or during the password recovery procedure.

Background

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.

Problem Symptoms

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.

Workaround/Solution

Whenever an access point's installation key is deleted, you must Return Materials Authorizations (RMA) the unit. 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
