Troubleshooting 

This appendix suggests solutions for problems you may 
encounter in installing or using the Wireless Gateway, and 
provides instructions for using several IP utilities to diagnose 
problems.  

Contact Customer Support if these suggestions do not resolve 
the problem. 

Troubleshooting Suggestions 

Problem 

Troubleshooting Suggestion 

LEDs 

Power LED does not 
illuminate after 
product is turned on. 

Verify that you are using the power cable 
provided with the device and that it is 
securely connected to the Wireless 
Gateway and a wall socket/power strip. 

LINK LAN LED does 
not illuminate after 
Ethernet cable is 
attached. 

Verify that the Ethernet cable is securely 
connected to your LAN hub or PC and to 
the Wireless Gateway. Make sure the PC 
and/or hub is turned on. 
Verify that your cable is sufficient for your 
network requirements. A 100 Mbit/sec 
network (10BaseTx) should use cables 
labeled CAT 5. A 10Mbit/sec network may 
tolerate lower quality cables. 

Internet Access 

My PC cannot access 
the Internet 

Use the ping utility (discussed in the 
following section) to check whether your PC 
can communicate with the device’s LAN IP 
address (by default 192.168.200.254). If it 
cannot, check the Ethernet cabling.  
If you statically assigned a private IP 
address to the computer, (not a registered 
public address), verify the following: 

•

 

Check that the gateway IP address 
on the computer is your public IP 
address (see Current Status for 
instructions on viewing the IP 
information.) If it is not, correct the 
address or configure the PC to 
receive IP information 
automatically. 

•

 

Verify with your ISP that the DNS 
server specified for the PC is valid. 
Correct the address or configure 
the PC to receive this information 
automatically. 

My LAN PCs cannot 
display web pages 
on the Internet. 

Verify that the DNS server IP address 
specified on the PCs is correct for your ISP, 
as discussed in the item above. If you 
specified that the DNS server be assigned 
dynamically from a server, then verify with 
your ISP that the address configured on the 
Wireless Gateway is correct, then You can 
use the ping utility, to test connectivity with 
your ISP’s DNS server.
