While facing a sudden disconnection issue or slow data transfer problems, a user has to make sure that the correct MTU value has been assigned to the router’s network. You can change the MTU (Maximum Transmission Value) of the network through the web interface of the linksyssmartwifi.com window. Experts recommend not to bring any changes in the default MTU value of the router. The default MTU value set in the network of the Linksys router is 1499. Make sure you only change the MTU value when you are sure that the issue caused in the MTU is because of the incorrect MTU.
