D-Link DIR-601 User Manual

Section 6 - 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 find your MTU, you can now configure 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 (192.168.0.1) and click 

OK

•  Enter your username (admin) and password (blank by default). Click 

OK

 to enter the web configuration page for the device. 

•  Click on 

Setup

 and then click 

Manual Configure

.  

•  To change the MTU enter the number in the MTU field and click 

Save Settings

 to save your settings. 

•  Test your e-mail. If changing the MTU does not resolve the problem, continue changing the MTU in increments of ten.
