Troubleshooting

A

Make sure the cable connecting from your cable or DSL modem is connected to the router’s Internet port. Verify that the Status page of the router’s configuration utility shows a valid IP address from your ISP.

Turn off the computer, router, and cable/DSL modem. Wait 30 seconds, and then turn on the router, cable/DSL modem, and computer. Check System > Summary from the router’s configuration utility to see if you get an IP address.

I am not able to access the router’s configuration utility Setup window.

Refer to “I want to test my Internet connection.,” on page 118 to verify that your computer is properly connected to the router.

STEP 2 Verify that your computer has an IP Address, Subnet Mask, Gateway, and DNS.

STEP 3 Set a static IP address on your system; refer to “I need to set a static IP address on a PC.” on page 116 above.

STEP 4 Refer to “I am a PPPoE user and I need to remove the proxy settings or the dial-uppop-up window.,” on page 124.

I can’t get my Virtual Private Network (VPN) to work through the router.

Access the router’s web interface by going to http://192.168.1.1 or the IP address of the router, and go to VPN > VPN Pass Through. Make sure you have IPSec passthrough and/or PPTP passthrough enabled.

VPNs that use IPSec with the ESP (Encapsulation Security Payload known as protocol 50) authentication will work fine. At least one IPSec session will work through the router; however, simultaneous IPSec sessions may be possible, depending on the specifics of your VPNs.

VPNs that use IPSec and AH (Authentication Header known as protocol 51) are incompatible with the router. AH has limitations due to occasional incompatibility with the NAT standard.

Change the IP address for the router to another subnet to avoid a conflict between the VPN IP address and your local IP address. For example, if your VPN server assigns an IP address 192.168.1.X (X is a number from 1 to 254) and your local LAN IP address is 192.168.1.X (X is the same number used in the VPN IP address), the router will have difficulties routing information to the right location. If you change the router’s IP address to 192.168.2.1, that should solve the problem. Change the router’s IP address through the Setup menu of the configuration utility. If you
