5.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 to solve your problem.

5.1The ADSL Router is not functional

1.Check to see that the power LED is green and than the network cables are installed correctly. Refer to the easy start guide for more details.

2.Check to see that the ETH/LAN and PPP/WAN LEDs are green.

3.Check to see that the DSL LED is green

4.Make sure you are not connecting the USB and the Ethernet port at the same time. You must only use 1 interface at a time.

5.Check the settings on your PC. Again, refer to the easy start guide for more details

6.Check the ADSL Router’s settings.

7.From your PC, can you PING the ADSL Router? Assuming that the ADSL Router has DHCP enabled and your PC is on the same subnet as the gateway, you should be able to PING the gateway.

8.Can you PING the WAN IP? Your ISP should have provided the IP address of their server. If you can ping the ADSL Router and your protocols are configured correctly, you should be able to ping the ISPs network. If you cannot PING the ISPs network, make sure you are using the correct protocols with the correct VPI/VCI values.

9.Make sure NAT is enabled for your connection. If NAT is disabled the ADSL Router will not route frames correctly (except in Bridge connection).

5.2I can’t connect to the ADSL Router.

1.Check to see that the power LED is green and that the network cables are installed correctly; see the easy start guide for more details.

2.Make sure you are not connecting the USB and the Ethernet port at the same time. You must only use 1 interface at a time.

3.Make sure that your PC and the ADSL Router is on the same network segment. The ADSL Router’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.

4.Also, your PC’s Subnet Mask should match the gateways subnet mask. The gateway has a default subnet mask of 255.255.255.0.

5.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.

6.Make sure NAT is enabled for your connection. If NAT is disabled the ADSL Router will not route frames correctly (except in Bridge connection).
