Appendix A -Troubleshooting
Check the following before you contact local Technical Support.
1
If wireless clients cannot access the network, check the following:
Be sure the AP 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.
2
If the AP cannot be configured using the Telnet, a web browser, or SNMP software:
Be sure that the AP has been configured with a valid IP address, subnet mask and default
gateway.
If VLANs are enabled on the AP, the management station should be configured to send
tagged frames with a VLAN ID that matches the AP's management VLAN (default VLAN
1). However, to manage the AP from a wireless client, the AP Management Filter should be
disabled.
Check that you have a valid network connection to the AP and that the Ethernet port or the
wireless interface that you are using has not been disabled.
If you are connecting to the AP through the wired Ethernet interface, check the network
cabling between the management station and the access point. If you are connecting to AP
from a wireless client, ensure that you have a valid connection to the AP.
If you cannot connect using Telnet, you may have exceeded the maximum number of
concurrent Telnet sessions permitted (i.e, four sessions). Try connecting again at a later
time.
3
If you cannot access the on-board configuration program via a serial port connection:
Be sure you have set the terminal emulator program to VT100 compatible, 8 data bits, 1
stop bit, no parity and 9600 bps.
