I am unable to send an email Outlook and Outlook Express, with and without adjusting my MTU value.

This problem is usually caused by an authorization problem.  To resolve the issue, please follow these instructions:

  1. Open a Web browser and input the Router’s IP Address into the “Address” bar (192.168.1.1 is the default IP address of the Router), then click on the Go button.
  2. A prompt for a “User Name” and “Password” will appear, leave the “User Name” blank, and input the routers password (admin is the default password).  Once you type in the password click on the OK button.
  3. Click on the Applications & Gaming tab, and then click on the Port Triggering sub-tab.
  4. Once you've done this, the “Port Triggering” tab will appear.  Here is an example of how to fill out the ports:

Application Name

TriggerPort Range

IncomingPort Range

E-mail

25 ~ 25

113 ~ 113
  1. After inputting the information above, click on the Save Settings button.

After the settings have been applied, e-mail should work normally.
