5 Troubleshooting 

None of the LEDs 
turn on when you 
turn on the ZyAIR. 

Make sure that you have the correct power adaptor connected to the ZyAIR and 
plugged in to an appropriate power source. Check all cable connections. 

If the LEDs still do not turn on, you may have a hardware problem. In this case, you 
should contact your local vendor. 

Cannot access the 
ZyAIR from the LAN. 

Check the cable connection between the ZyAIR and your computer or hub. Refer to 
section 1.2 for details.  

Ping the ZyAIR from a LAN computer. Make sure your computer’s Ethernet adapter 
is installed and functioning properly. 

Make sure that the IP address and the subnet mask of the ZyAIR and your 
computer(s) are on the same subnet. 

Cannot get a WAN 
IP address from the 
ISP. 

Check your Internet connection settings (refer to section 3.2). 

You need a user name and password if you’re using PPPoE or PPTP encapsulation. 
Make sure that you have entered the correct Service Name (PPPoE encapsulation 
only), username and password (the username and password are case sensitive). 
Refer to section 3.2 for more information. 

Cannot access the 
Internet.
