If you only have one computer and one networked printer plugged into your four-port router (and everything else on your network is Wi-Fi based) there is no need to upgrade to gain physical ports. Note: You only need to upgrade if you’re running out of physical ports for hard line connections. If you need more than four Ethernet connections you’ll need to upgrade to a router with a larger port bank (a rather expensive proposition that will usually only boost you up to eight ports) or you can pick up a dedicated switch. Most routers have four Ethernet ports which allow you to plug in four devices and have them communicate via the switch function. Without the switching function the devices could talk through the router to the greater internet but not to each other-something as simple as copying an MP3 from your laptop to your desktop over the network would be impossible. A network switch is a piece of hardware that facilitates communication between computers on an internal network. ![]() ![]() In addition to the inside-to-outside network functionality outlined above, home routers also act as a network switch. Even for a user with a single computer a simple $50 router is worth it for the firewall functionality alone. On the other hand, if a sudden burst of port probing comes in from an unknown address your router acts as a bouncer and rejects the requests, effectively cloaking your computers. If you request a music stream from Pandora, for example, your router says, “We’re expecting you, come on in” and that stream of data is directed to the device that made the request. Firewall: Routers act as basic firewalls in a variety of ways including automatically rejecting incoming data that is not part of an ongoing exchange between a computer within your network and the outside world.DHCP does that for you automatically so that when you plug your XBOX into your router, your friend gets on your wireless network, or you add a new computer, an address is assigned with no human interaction required. ![]() This means every time a new computer entered the network you would have to manually assign it an address on the network.
