• Check if other PCs work. If they do, ensure that your workstation’s IP set-
tings are correct (IP Address, Subnet Mask, Default Gateway, and DNS).
Restart the computer that is having a problem.
• If the PCs 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 LAN and power connec-
tions.)
• If the Router is configured correctly, check your Internet connection
(DSL/cable modem, etc.) to see if it is working correctly. You can remove
the Router to verify a direct connection.
• Manually configure the TCP/IP with a DNS address provided by your
ISP.
• Make sure that your browser is set to connect directly and that any dial-
up is disabled. For Internet Explorer, click

15. I can't access my email, web, or VPN, or I am getting corrupted data from the
Internet.
The Maximum Transmission Unit (MTU) setting may need to be adjusted. By
default, the MTU is set at 1500. For most DSL users, it is strongly recom-
mended to use MTU 1492. If you are having some difficulties, perform the fol-
lowing steps:
A. To connect to the Router, go to the web browser, and enter
http://192.168.1.1
or the IP address of the Router.
B. Enter the password, if asked. (The default password is
admin
.)
C. On the Basic Setup tab, look for the MTU option, and select
Enable
. In the
Size field, enter
1492
.
D. Click the
Save Settings
button to continue.
If your difficulties continue, change the
Size
to different values. Try this list of
values, one value at a time, in this order, until your problem is solved:
1462
1400
1362
1300
16. I need to use port triggering.
Port triggering looks at the outgoing port services used and will trigger the
Router to open a specific port, depending on which port an Internet application
uses. Follow these steps:
A. To connect to the Router, go to the web browser, and enter
http://192.168.1.1
or the
IP address
of the Router.
B. Enter the password, if asked. (The default password is
admin
.)
C. Click the
Applications & Gaming => Port Triggering
tab, and click the
Port Trigger
button.
D. Enter any name you want to use for the Application Name.
E. Enter the Start and End Ports of the Triggered Port Range. Check with your
Internet application provider for more information on which outgoing port
services it is using.
F. Enter the Start and End Ports of the Forwarded Port Range. Check with
your Internet Application provider for more information on which incom-
ing port services are required by the Internet application.
