You may want to connect your desktops, laptops, printers and other machines at your home to the internet and achieve the information sharing. Perhaps you just want to connect your smart phone via WiFi when you’re at home to reduce the usage of your mobile data plan. To complete that, all you need to know is how to build a home network. There are lots of ways to set one up. I’ll introduce the basic setup for the most common case. For person that already have a network, I’II tell ways about how to expand the existing home network in this blog too.Usually, your broadband connection being cable, DSL,free sample or something else will first go through some kind of device typically called a modem. The modem’s job is to convert the broadband signal to Ethernet. You’ll connect that Ethernet from your broadband modem to a broadband router. Router, as its name implies, is used to “route” information between computers on your home network and between those computers and the broadband connection to the Internet. Each of your computers already has an Ethernet adapter. An Ethernet cable will run from each computer to the router and another cable will connect the router to the modem.
Most laptops and portable devices (and even a few desktops) support wireless connection via a technology known as WiFi. WiFi is a short-range wireless technology that you need to provide on your home network, if you want to be able to use it. The most common approach to include wireless capabilities in your network is by using a wireless router.
The wireless router combines the functions of two devices: the router, just as we saw before, and a wireless access point. A wireless access point, occasionally abbreviated WAP, is simply a network device that converts the wired Ethernet signals into wireless WiFi signals and vice-versa. Wireless routers are actually more common than their wired-only counterparts in the home and small business networking market. In fact, even if you don’t have a wireless device today, I typically recommend getting a wireless router anyway for future expansion.The number of internet-connected devices that we now deal with is pretty amazing. A typical wireless router or router with a wireless access point can easily handle dozens of devices connected wirelessly. However, wired devices may present problems. Many home routers – wired or wireless – come with only a limited number of connections. It’s common for there to be exactly five connections: one for the internet (“WAN” or modem) and then four for networked devices.
