A NAT router permits you to share a single broadband connection among numerous computers and other networked devices. Each of your computers will need an Ethernet adapter, and most will already include them. An Ethernet cable will run from each computer to the router, and an extra cable will attach the router to the modem. Some ISPs offer a shared modem/router. That means that the 2 separate devices; the modem and router, are positioned into a single box. Your external connection goes in one connection, and one or more Ethernet ports are provided to which you attach to your devices. Each computer connected to this network will also be required to support the TCP/IP communications protocol.
TCP/IP is the essential ‘language’ of communication on the internet. IP stands for Internet Protocol. Windows contains TCP/IP support, by default. Regrettably, configuration specifics for your router’s connection to the internet are limited to both your ISP or broadband provider and the specific model of router that you are using, so I can’t cover that in detail. You’ll also need to check with your ISP and your router’s documentation. As for the router’s connection to your individual devices, the default configurations of both the router and most recent devices will typically work. Adding multiple wireless access points, extending networks over greater distances, and adding extra layers of perhaps security or functionality can all add complexity. However, to facilitate this transition, you should employ an external DNS service such as ChangeIP.com which costs under $10/year to conserve your IPs and make this transition easier.
