Troubleshooting
Check the following items before you contact technical support.
1. If wireless clients cannot access the network, check the
following:
• Be sure the access point and the wireless clients are
configured with the same Service Set ID (SSID).
• If authentication or encryption are enabled, ensure that
the wireless clients are properly configured with the
appropriate authentication or encryption keys.
• If authentication is being performed through a RADIUS
server, ensure that the clients are properly configured on
the RADIUS server.
• If authentication is being performed through IEEE 802.1x,
be sure the wireless users have installed and properly
configured 802.1x client software.
• If MAC address filtering is enabled, be sure the client’s
address is included in the local filtering database or on the
RADIUS server database.
• If the wireless clients are roaming between access points,
make sure that all the access points and wireless devices
in the Extended Service Set (ESS) are configured to the
same SSID, and authentication method.
