Nighthawk X4S AC2600 Smart WiFi Router If a device in the data path uses a lower MTU setting than the other devices, the data packets must be split or "fragmented" to accommodate the device with the smallest MTU. The best MTU setting for NETGEAR equipment is often the default value. In some situations, changing the value fixes one problem but causes another. 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 • MSN portal • America Online's DSL service • 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. Note An incorrect MTU setting can cause Internet communication problems. For example, you might not be able to access certain websites, frames within websites, secure login pages, or FTP or POP servers. To change the MTU size: 1. Launch a web browser from a computer or WiFi device that is connected to the network. 2. Type http://www.routerlogin.net . A login window opens. 3. Enter the router user name and password. The user name is admin. The default password is password. The user name and password are case-sensitive. The BASIC Home page displays. Specify Your Internet Settings 33
