If you want to connect more wired devices than your router has Ethernet ports, add a gigabit Ethernet switch. Connect one cable from your router to the switch, then plug your devices into the switch’s remaining ports.
Switches come in a range of sizes and prices. If you just need a simple, reliable, inexpensive one, we recommend this model. Whichever you choose, look for one rated at gigabit or faster so it doesn’t limit your speed.
