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. Click the Advanced => Filter tab.
D. Look for the MTU option, and select Enable. In the Size field, enter 1492.
E. Click the Apply 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 Advanced => Forwarding tab, and click the Port Trigger button.
D. Enter any name you want to use for the Application Name.
E. Enter the Triggered Port Range. Check with your Internet application
provider for more information on which outgoing port services it is using.
F. Enter the Incoming Port Range. Check with your Internet Application
provider for more information on which incoming port services are
required by the Internet application.
