Troubleshooting - Foundry Networks IronPoint 200 User Manual

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 pre-shared key, authentication or encryption keys. The
wireless client's NIC must have the necessary drivers to support the security and
authentication methods configured on the access point.
• 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 access point cannot be configured using the Telnet, a Web browser, or SNMP software:
• Be sure to have configured the access point with a valid IP address, subnet mask and default
gateway.
• If VLANs are enabled on the access point, the management station should be configured to
send tagged frames with a VLAN ID that matches the access point's management VLAN
(default VLAN 1, see "management-vlanid" on page 22-2). However, to manage the access
point from a wireless client, the access point Management Filter should be disabled (see
"filter ap-manage" on page 17-3).
• Check that you have a valid network connection to the access point and that the Ethernet port
or the wireless interface that you are using has not been disabled.
• If you are connecting to the access point through the wired Ethernet interface, check the
network cabling between the management station and the access point. If you are connecting
to access point from a wireless client, ensure that you have a valid connection to the access
point.
