The first router I saw was in the mid 1990s. The company I worked for was a very early adopter of the Internet, at least in the commercial world. After spending a couple of nights with the network manager and his technical support guy dragging Ethernet and coaxial cables through the office roof space we hooked everything up through a router that cost more than most of us earned that year. Today, more than 20 years later, a faster and more capable device costs less than a day's pay for some of us.
Synology's RT2600ac router, at a touch under $400 (if you pay full retail) lets you connect printers and external storage using USB, four devices over gigabit Ethernet, and wireless devices using 802.11 b/g/n/a/ac.
