4. APPENDIX A: TROUBLESHOOTING
Below is a list of commonly asked questions. Before calling technical support, please look through
these issues to see if they help solve your problem.
4.1 THE GATEWAY IS NOT FUNCTIONAL
1. Check to see that the power LED is green and than the network cables are installed
correctly. Refer to the quick start guide for more details.
2. Check to see that the LAN and WAN LEDs are green.
3. Check to see that the DSL LED is green
4. Check the settings on your PC. Again, refer to the quick start guide for more
details
5. Check the gateway’s settings.
6. From your PC, can you PING the gateway? Assuming that the gateway has DHCP
enabled and your PC is on the same subnet as the gateway, you should be able to
PING the gateway.
7. Can you PING the WAN? Your ISP should have provided the IP address of their
server. If you can ping the gateway and your protocols are configured correctly,
you should be able to ping the ISPs network. If you cannot PING the ISPs
network, make sure your using the correct protocols with the correct VPI/VCI
values.
8. Make sure NAT is enabled for your connection. If NAT is disabled you the
gateway will not route frames correctly.
4.2 I CAN’T CONNECT TO THE GATEWAY
1. Check to see that the power LED is green and that the network cables are installed
correctly; see the quick start guide for more details.
2. Make sure that your PC and the gateway is on the same network segment. The
gateway’s default IP address is 192.168.1.1. If you are running a Windows based
PC, you can open a DOS window and type IPCONFIG; make sure that the network
adapter that is connected to the gateway is within the same 192.168.1.x subnet.
3. Also, your PC’s Subnet Mask should match the gateways subnet mask. The
gateway has a default subnet mask of 255.255.255.0.
4. If this still does not work, press the reset button for 10 seconds. This will place the
gateway into its factory default state. Go through the above procedures again.
5. Make sure NAT is enabled for your connection. If NAT is disabled you the
gateway will not route frames correctly.
4.3 DSL LINK LED CONTINUES TO BLINK BUT DOES NOT GO
SOLID
1. This means that the DSL line is trying to train but for some reason it cannot establish a valid
connection. The main cause of this is that you are too far away from the central office.
Contact your DSL service provider for further assistance.
Common Problems and Solutions
4.4 DSL LINK LED IS ALWAYS OFF
1. Make sure you have DSL service. You should get some kind of information from your ISP
which states that DSL service is installed. You can usually tell if the service is installed by
listening to the phone line; you will hear some high-pitched noise. If you do not hear high-
pitched noise, contact your ISP.
