How to Enable Flow Control on a Router

By | February 13, 2018

Not all routers allow you to configure flow control. In fact, most routers do not. Flow control is mainly a function of a network switch. However, some models of routers, like those with built-in switch capabilities (known also as a “smart switch”), will allow the user to set flow control for each port or device connected to the network. Linksys and Netgear both manufacture routers with the smart switch capabilities.
