Section 8 - Troubleshooting
You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a fragmented
packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example, lets say that 1452 was the
proper value, the actual MTU size would be 1480, which is the optimum for the network we’re working with (1452+28=1480).
Once you nd your MTU, you can now congure your router with the proper MTU size.
To change the MTU rate on your router follow the steps below:
• • Open your browser, enter the IP address of your router (192.168.0.1or http://dlinkrouter.local.) and click OK.
•
• • Enter your username (admin) and password (blank by default). Click OK to enter the web conguration page for
the device.
•
• • Click on Setup and then click Manual Congure.
•
• • To change the MTU enter the number in the MTU eld and click Save Settings to save your settings.
•
• • Test your email. If changing the MTU does not resolve the problem, continue changing the MTU in increments of
ten.
