Section 7 - Viewing Status and Statistics Authentication Failed Path: Status > Wireless Information > Access Point > Authentication Failed An access point might fail to associate to the wireless controller due to errors such as invalid packet format or vendor ID, or because the access point is not configured as a valid access point with the correct local or RADIUS authentication information. The Authentication Failed APs List page shows information about access points that failed to establish communication with the wireless controller. Right-click on an AP to bring up options to manage, or to view details. An access point can fail due to any of the reasons: Failure No Database Entry Local Authorization Not Managed RADIUS Authentication RADIUS Challenged RADIUS Unreachable Invalid RADIUS Response Invalid Profile ID Profile Mismatch Description MAC address of the access point is not in the local Valid AP database or the external RADIUS server database, so the access point has not been validated. Authentication password configured in the access point did not match the password configured in the local database. Access point is in the Valid AP database, but the access point Mode in the local database is not set to Managed. The password configured in the RADIUS client for the RADIUS server was rejected by the server. The RADIUS server is configured to use the Challenge-Response authentication mode, which is incompatible with the access point. The RADIUS server that the access point is configured to use is unreachable. The access point received a response packet from the RADIUS server that was not recognized or invalid. The profile ID specified in the RADIUS database may not exist on the controller. This can also happen with the local database when the configuration has been received from a peer controller. Hardware Type: The access point hardware type specified in the access point Profile is not compatible with the actual access point hardware. D-Link DWC-2000 User Manual 217
