Wireless Troubleshooting
If following symptoms happen on the access point
Make sure you are using the supplied power adapter and that it is plugged in to an appropriate power source. Check that the power source is turned on. If the problem persists, you may have a hardware problem. In this case, you should contact your local vendor.
The supplied power to ZyAIR is too low. Check that the ZyAIR is receiving enough power. ¡@
How can I check to be sure if I am interfered or not ?
There may not be an easy or quick answer to this. One thing to notice first is whether the problems are continuous or intermittent. Interference usually occurs intermittently, or else it would have likely been noticed when the link was first commissioned.
If I've confirmed it is an interference problem. What should I do?
Change the location and choose other radio channel to see whether the impact of the interference decreases and the link quality improves.
What should I do if I have low signal or high noise ?
To improve the signal, check or get the antennas with reverse SMA type connectors. For noise problems, please shield or remove the interference. If the situation doesn't improve, please change radio channels.
Unable to associate to the access point
You can verify the result of association by using wireless
client utility or entering command "wlan association disp"
in SMT Menu 24.8..
B3000> wlan association disp |
Unable to authenticate to the access point
If your client adapter is unable to authenticate to an access point, check the security settings of your client adapter and the access point. These include the following areas:
Authentication with shared key (WEP):
If you use WEP shared key to authenticate the wireless clients, you should check whether following configuration parameters on both AP and wireless clients match:

Authentication with 802.1X:
If 802.1X security is used in your network, you can troubleshoot
the authentication through SMT Menu 24.3.1 -
System Maintenance - Log and Trace. Here is the format
of the log message:
¡@
802.1X with built-in user account:
[test] [0:a:8a:a2:ae:4e] [login success] [accepted by profiles] [test] [0:a:8a:a2:ae:4e] [login fail] [user password error related to profiles] [mars] [0:a:8a:a2:ae:4e] [login fail] [user not found in profiles] |
802.1X with RADIUS server:
[test] [0:60:b3:69:3:37] [login fail] [rejected by RADIUS server] [test] [0:60:b3:69:3:37] [auth enticating ...] [no response from RADIUS server] [test] [0:60:b3:69:3:37] [logout] [user requested] |
Note: Some wireless clients (for example, Symbol PCMCIA client) support open authentication and WEP encryption for data traffic. To support these clients in your network, you need to select either 'Open System' or 'Auto' for authentication method when WEP is enable. If you have a mix network which mean there are adapter from different vendor, the suggest configuration is 'Auto'. The system will automatically detect your adapter type and auto configure to the client adapter when WEP is enabled.
