Troubleshooting
Overview
A
This chapter covers some common problems that may be encountered while using the Wireless DSL Gateway and some possible solutions to them. If you follow the suggested steps and the Gateway still does not function properly, contact your Internet Service Provider or Technical Support for assistance.
General Issues
Problem: Can't connect to the Gateway to configure it.
Solution: Check the following:
•The Gateway is properly installed, connections are OK, and it is powered ON. Check the LEDs for Ethernet or USB port status.
•Ensure that your computer and the Gateway are on the same network segment.
•If your computer is set to "Obtain an IP Address automatically" (DHCP client), restart your computer.
Internet Access
Problem : When I enter a Web site address or IP address I get a time out error.
Solution: A number of things could be causing this. Try the following troubleshooting steps.
•Verify that other computers work. If they do, ensure that your computer’s IP settings are correct. If using a fixed (static) IP address, check the network mask, default Gateway and DNS settings as well as the IP address.
•If the computers are configured correctly, but still not working, check the Gateway. Ensure that it is connected and on. Connect to it and check its settings. (If you cannot connect to it, check the Ethernet and power connections.)
Problem: Some applications do not run properly when using the Gateway.
Solution: The Gateway processes the data passing through it, so it is not transparent.
•If you are running a supported Windows operating system, ensure that the UPnP feature is enabled.
•If this does not solve the problem or your operating system does not support UPnP you can use the DMZ function. This should work with almost every application, but:
-It is a security risk, since the firewall is disabled for the DMZ computer.
-Only one (1) computer can use this feature.
•A third option is to use the Firewall Snooze Control feature to temporarily disable the firewall to allow the application to function unimpeded.
