Change The Mtu Size - NETGEAR R6700v2 User Manual

Nighthawk AC1750 Smart WiFi Router Model R6700v2
Leave the MTU unchanged unless one of these situations occurs:
• You experience problems connecting to your ISP or other Internet service, and the technical support of
either the ISP or NETGEAR recommends changing the MTU setting. These web-based applications
might require an MTU change:
- A secure website that does not open or displays only part of a web page
- Yahoo email
• You use VPN and experience severe performance problems.
• You used a program to optimize MTU for performance reasons and now you are experiencing connectivity
or performance problems.
If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are willing to
experiment, you can gradually reduce the MTU from the maximum value of 1500 until the problem goes
away. The following table describes common MTU sizes and applications.
