C.Make sure you are using the right Internet settings. Contact your ISP to see if your Internet connection type is DHCP, Static IP Address, or PPPoE (commonly used by DSL consumers). Please refer to the Basic Setup section of “Chapter 5: Configuring the Router” for details on Internet Connection Type settings.

D.Make sure you use the right cable. Check to see if the Internet LED is solidly lit.

E.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 Web-based Utility shows a valid IP address from your ISP.

F.Turn off the computer, Router, and cable/DSL modem. Wait 30 seconds, and then turn on the Router, cable/DSL modem, and computer. Check the Status tab of the Router’s Web-based Utility to see if you get an IP address.

6.I am not able to access the Router’s Web-based Utility Setup page.

A.Refer to “Problem #4, I want to test my Internet connection” to verify that your computer is properly connected to the Router.

B.Refer to “Appendix C: Finding the MAC Address and IP Address for Your Ethernet Adapter” to verify that your computer has an IP Address, Subnet Mask, Gateway, and DNS.

C.Set a static IP address on your system; refer to “Problem #3: I need to set a static IP address on a PC.”

D.Refer to “Problem #12: I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window.”

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

Access the Router’s web interface by going to http://192.168.15.1 or the IP address of the Router, and go to the Security => VPN Passthrough tab. 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.
