Do I need a network switch or a router?

A router connects your network to the internet and assigns IP addresses. A switch adds more Ethernet ports to your existing network. You need a router first — then add a switch if you need more wired connections. They complement each other.

Does a switch slow down my network?

No. Modern Gigabit switches operate at wire speed — every port runs at full Gigabit simultaneously with no bottleneck. Adding a switch does not slow down your network at all.
