A-2

I cannot access 
the ZyAIR from 
the Ethernet 

If all of the LAN LEDs on the front panel are off, check the Ethernet cable 
connection between your ZyAIR and the computer connected to the LAN port. 

Check for faulty Ethernet cables. 

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

Verify that the IP addresses and the subnet masks of the ZyAIR and the computer 
are on the same subnet. 

I cannot ping any 
computer on the 
LAN. 

If all of the LAN LEDs on the front panel are off, check the Ethernet cable 
connection between your ZyAIR and the computer connected to the LAN port. 

Verify that the IP addresses and the subnet masks of the ZyAIR and the computers 
are on the same subnet. 

The ISP provides the WAN IP address after authenticating you. Authentication may 
be through the user name and password, the MAC address or the host name. 

I cannot get a WAN 
IP address from the 
ISP. 

The username and password apply to PPPoE and PPTP encapsulation only. Make 
sure that you have entered the correct Service Type, User Name and Password (be 
sure to use the correct casing). Refer to the WAN Screens chapter (web configurator) 
or the Internet Access chapter (SMT). 

 

Clone the MAC address from your computer on the LAN as the ZyAIR’s WAN MAC 
address. Refer to the WAN Screens chapter (web configurator) or the General and 
WAN Setup chapter (SMT). It is recommended that you clone your computer’s MAC 
address, even if your ISP presently does not require MAC address authentication. 

 

Configure your computer’s name as the ZyAIR’s system name. Refer to the Wizard 
Setup chapter (web configurator) or the General and WAN Setup chapter (SMT).
