Troubleshooting
Overview
This chapter covers some common problems that may be encountered while using the router and some
possible solutions to them. If you follow the suggested steps and the router still does not function
properly, contact your Internet Service Provider or Technical Support for assistance.
General Issues
Problem: Can't connect to the router to configure it.
Solution: Check the following:
• The router is properly installed, connections are OK, and it is powered ON. Check the
LEDs for Ethernet port status.
• Ensure that your computer and the router 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
router and DNS settings as well as the IP address.
• If the computers are configured correctly, but still not working, check the router.
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 router.
Solution: The router 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.
• Another option is to use the Firewall Snooze Control feature to temporarily disable
the firewall to allow the application to function unimpeded.
