Chapter 39 Troubleshooting
• Authentication of the wireless client with the authentication server may have
failed. Ensure the AP profile assigned to the AP uses a security profile that is
properly configured and which is matches the security settings in use by the
NXC. For example, if the security mode on the AP is set to WPA/WPA2 then
make sure the authentication server is running and able to complete the 802.1x
authentication sequence. See
163
for more.
• If you cannot solve the problem on your own, before contacting Customer
Support use the built-in wireless frame capture tools
to capture data that can be used for more granular troubleshooting procedures.
To use the built-in wireless frame capture tool, first set up a second NWA5160N
nearby to act as a Monitor AP
The AP status is registered as offline even though it is on.
• Check the network connections between the NXC and the AP to ensure they are
still intact.
• The AP may be sufferering from instability. Disconnect it to turn its power off,
wait some time, then reconnect it and see if that resolves the issue.
• The CAPWAP daemon may be down. You can use the NXC's built-in diagnostic
tools and CLI console to get CAPWAP debug messages which can later be sent to
customer service for analysis. See
A wireless client cannot be authenticated through the Captive Portal.
If the Captive Portal redirects a wireless client to a failed login page or an internal
server error page, then the authentication server may not be reachable. Make
sure that the NXC can reach it if is external to the LAN by opening the Console
Window and pinging the server's IP address.
Wireless clients are not being load balanced among my APs.
• Make sure that all the APs used by the wireless clients in question share the
same SSID, security, and radio settings.
• Make sure that all the APs are in the same broadcast domain.
• Make sure that the wireless clients are in range of the other APs; if they are only
in range of a single AP, then load balancing may not be as effective.
