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 bridges, make sure that all the
bridges and wireless devices in the Extended Service Set (ESS) are
configured to the same SSID, and authentication method.
4 If the bridge cannot be configured using the Telnet, a web browser, or SNMP
software:
Be sure to have configured the bridge with a valid IP address, subnet mask
and default gateway.
If VLANs are enabled on the bridge, the management station should be
configured to send tagged frames with a VLAN ID that matches the
bridge’s management VLAN (default VLAN 1,
page 15). However, to
manage the bridge from a wireless client, the AP Management Filter should
be disabled (
page 15).
Check that you have a valid network connection to the bridge and that the
Ethernet port or the wireless interface that you are using has not been
disabled.
If you are connecting to the bridge through the wired Ethernet interface,
check the network cabling between the management station and the
bridge. If you are connecting to bridge from a wireless client, ensure that
you have a valid connection to the bridge.
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.
5 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.
Check that the serial cable conforms to the pin-out connections provided
on page B-3.
6 If you forgot or lost the password:
Contact your local Technical Support for help.
7 If all other recovery measure fail, and the bridge is still not functioning
properly, take any of these steps:
