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 access point with the proper MTU size.
To change the MTU rate on your access point follow the steps below:
• Open your browser, enter the IP address of your access point (192.168.0.50) 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 email. If changing the MTU does not resolve the problem, continue changing the MTU in increments
of ten.
