You should start at 1424 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 1402
was the proper value, the actual MTU size would be 1480, which is the optimum for
the network we’re working with (1402+28=1430).
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 (192.168.1.1) and click OK.
• Enter your user name (admin) and password (admin). Click OK to enter the web
configuration page for the device.
• Click on WAN Setting and then click WAN Interface.
• To change the MTU enter the number in the MTU field and click Apply to save your
settings.
• Test your email. If changing the MTU does not resolve the problem, continue
changing the MTU in increments of ten.
3. What is WPA?
WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve
the security features of WEP (Wired Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP
scrambles the keys using a hashing algorithm and, by adding an integrity-checking
feature, ensures that the keys haven’t been tampered with. WPA2 is based on
802.11i and uses Advanced Encryption Standard (AES) instead of TKIP.
• User authentication, which is generally missing in WEP, through the extensible
