6 Troubleshooting 

The PWR/SYS 
LED is off. 

Make sure you are using the correct power adaptor and the power adaptor is 
plugged into an appropriate power supply. 

 

Unplug the power adaptor and plug it in again. If the error persists, you may have a 
hardware problem. In this case, you should contact your vendor. 

The ETHN LED is 
off. 

Check the cable connection to the ZyAIR ETHERNET port.  

Make sure your computer’s network card is working properly. 

I cannot access 
the web 
configurator. 

Make sure the IP addresses and subnet masks of the ZyAIR and the computer are 
in the same IP address range. (For example, if the ZyAIR is using the default IP 
address and subnet mask, check that the IP address of the computer is in the range 
192.168.1.3 ~192.168.1.254 and the subnet mask is 255.255.255.0). Refer to the 
Setting Up Your Computer’s IP Address section.  

If you change the ZyAIR default IP address, then enter the new IP address as the 
web site address. 

The default password is “1234”. If you have changed the password and have now 
forgotten it, you will need to reset the ZyAIR. Refer to the User’s Guide for how to 
use the RESET button. 

I cannot ping any 
computer on the 
wireless LAN. 

If the ETHN LED is off, check the cables between the ZyAIR and your computer or 
hub. 

Verify that the IP address and the subnet mask of the ZyAIR and the computers are 
in the same range.
