I cannot ping any 
computer on the 
LAN. 

If the ETHN LED on the front panel is off, check the Ethernet cable connections 
between your ZyAIR and the Ethernet device. 

Check the Ethernet cable connections between the Ethernet device and the LAN 
computers. 

Check for faulty Ethernet cables. 

Make sure the LAN computer’s Ethernet adapter is installed and working properly. 

Verify that the IP address and the subnet mask of the ZyAIR, the Ethernet device 
and the LAN computers are on the same subnet. 

I cannot access 
the ZyAIR. 

The Password and Username fields are case-sensitive. Make sure that you enter 
the correct password and username using the proper casing. 

Use the RESET button on the top panel of the ZyAIR to restore the factory default 
configuration file (hold this button in for about 10 seconds or until the link LED turns 
red). This will restore all of the factory defaults including the password.  

I cannot access 
the ZyAIR through 
Telnet.  

Refer to the Problems with the Ethernet Interface section for instructions on checking 
your Ethernet connection.
