Network Connection Speeds

Curious about just how fast your network should be or what the top speed of different networks are?  Well, here's a short but simple list of the most popular network connection speeds.  These are top speeds and actual connection speeds vary due to the amount of network traffic and availability of bandwidth. Also keep in mind that if you have a Gigabit network (1,000 Mbps) and all of your components are Gigabit but you have one computer that is 100Mbps, you will cause your entire network including switches, routers, hubs and other machines to slow to the communication of that 100Mbps machine. Here is a general rule: "Your computer network is only as fast as the slowest connected device."
