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.
The ADSL Router is not functional
1. Check to see that the power LED is red and than the network cables are installed correctly.
2. Check to see that the ETH/LAN, ADSL and PPP LEDs are green.
3. Check to see that the ADSL LED is green
4. Check the settings on your PC.
5. 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.
6. 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.
7. Make sure NAT is enabled for your connection. If NAT is disabled the ADSL Router will
not route frames correctly (except in Bridge connection).
I can’t connect to the ADSL Router.
1. Check to see that the power LED is red and that the network cables are installed correctly.
2. 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 adapt-
er that is connected to the gateway is within the same 192.168.1.x subnet. For Windows
98 SE computers you need to run ‘winipcfg’ (Start>Run>winipcfg).
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 gate-
way into its factory default state. Go through the above procedures again.
5. Make sure NAT is enabled for your connection. If NAT is disabled the ADSL Router will
not route frames correctly (except in Bridge connection).
The 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 of-
fice. Contact your DSL service provider for further assistance.
2. Verify that the phone line is connected directly to the wall and to the line input on the
ADSL Router.
3. Make sure that for every parallel phone line connected to telephone or fax to install with a
micro filter.
