A user experiencing problems from the Internet service, slow data transfer problem, or sudden loss of Internet connection is recommended to change the MTU (Maximum Transmission Unit) of the router. The best MTU setting for a Netgear router is considered as its default value. In some circumstances, changing the MTU value doesn’t resolve the connection issue. The default MTU value of a Netgear router is 1499, a value of more than 1500 units can burst the connection of your network. You can bring changes in the MTU of a router through the routerlogin.net interface.
