If the all 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 the faulty Ethernet cables.
Make sure the NIC (Network Interface Card) on the Ethernet device is installed and
working properly.
Check the IP address of the Ethernet device. Make sure that the IP address and the
subnet mask of the ZyAIR and the Ethernet device are on the same subnet.
I cannot ping any

14.4 Problem with the WAN Interface
Table 14-4 Troubleshooting the WAN Interface
PROBLEM CORRECTIVE ACTION
I cannot get a WAN IP
address from the ISP.
The WAN IP address is provided when the ISP recognizes the user as an
authorized user after verifying the MAC address, Host Name or User ID.
Find out the verification method used by your ISP.
If the ISP checks the LAN MAC address, inform the ISP of the ZyAIR ‘s WAN MAC
address. To view the WAN MAC address in SMT menu 24.1.
In case the ISP does not allow you to use a new MAC, you can clone the MAC from
the LAN as the WAN MAC and send it to the ISP using SMT menu 2. It is
recommended that you configure this menu even if your ISP presently does not
require MAC address authentication.
If the ISP checks the Host Name, enter host name in the System Name field in the
SMT menu 1 when you connect the ZyAIR to a cable/xDSL modem.
If the ISP checks the User ID, make sure that you have entered the correct Service
Type, user name (in the My Login field) and password (in the My Password field)
in SMT menu 4.
