D. Make sure you have the right cable. Check to see if the Internet column has
a solidly lit Link/Act LED.
E. Make sure the cable connecting from your cable or DSL modem is con-
nected 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.
4. I am not able to access the Setup page of the Router’s web-based utility.
A. Refer to “Problem #2, I want to test my Internet connection” to verify that
your computer is properly connected to the Router.
B. Refer to “Appendix D: 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 #1: I need to set a
static IP address.”
D. Refer to “Problem #10: I need to remove the proxy settings or the dial-up
pop-up window (for PPPoE users).”
5. I can’t get my Virtual Private Network (VPN) working 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 the
Security
tab. Make sure you have IPsec
pass-through and/or PPTP pass-through 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 incom-
patibility 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
tab

D. In the command prompt, type
ping
followed by your Internet or WAN IP
address
and press the
Enter
key. The Internet or WAN IP Address can be
found on the
Status
screen of the Router’s web-based utility. For example,
if your Internet or WAN IP address is 1.2.3.4, you would enter
ping 1.2.3.4
and press the
Enter
key.
• If you get a reply, the computer is connected to the Router.
• If you do NOT get a reply, try the ping command from a different com-
puter to verify that your original computer is not the cause of the problem.
E. In the command prompt, type
ping www.yahoo.com
and press the
Enter
key.
• If you get a reply, the computer is connected to the Internet. If you can-
not open a webpage, try the ping command from a different computer to
verify that your original computer is not the cause of the problem.
• If you do NOT get a reply, there may be a problem with the connection.
Try the ping command from a different computer to verify that your orig-
inal computer is not the cause of the problem.
3. I am not getting an IP address on the Internet with my Internet connection.
A. Refer to “Problem #2, I want to test my Internet connection” to verify that
you have connectivity.
B. If you need to register the MAC address of your Ethernet adapter with your
ISP, please see “Appendix D: Finding the MAC address and IP Address for
Your Ethernet Adapter.” If you need to clone the MAC address of your
Ethernet adapter onto the Router, see the System section of “Chapter 6: The
Router’s Web-based Utility” for details.
C. Make sure you are using the right Internet connection 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 Setup sec-
tion of “Chapter 6: The Router’s Web-based Utility” for details on Internet
connection settings.
