If you have just one computer that links directly to the net, and if you need only that one computer to complete everything on your to-do list, then you do not require a router. You have everything required.
If, however, your busy family has acquired computers almost as soon as bicycles and baseball gear, and in case every laptop-toting family member cries and screams for internet access, then you definitely need to invest a few dollars and an hour of the time, installing a router and making a home network for the family.
In technical terms, a router translates the signal out of your broadband or DSL internet service provider, routing them to the computers on the network. Before wireless networks became readily accessible, Router & Modem would transmit the signals through Ethernet or coaxial cable to all the remote locations on the household network. Now, wireless routers transmit radio signals in your wireless ready PCs all over the house. As the router broadcasts radio signals, your neighbours along with other malicious intruders may hijack the signal and make use of your network unless you protect it by encrypting its signals.
Like other computing devices, routers can be found in assorted sizes and strengths for a number of residential and light commercial applications. For the majority of families, an affordable wireless router from your local big-box electronics store provides all of the coverage and signal strength they ever will require. Installation is easy and straight-forward, plus it goes in accordance with intuition and common sense. Connect your modem in your broadband or DSL service, connect your router to your modem, and link all of your computers for your router. Naturally, the devil is within the details, but the best wireless routers now come with installation wizards that help you step-by-step through all the subtleties and intricacies of installation and configuration. Generally, setting up a home network is simple enough. However, if you are attempting to do a manual set up, the IP addresses which they need to be set are: 192.168..1 and 192.168.1.1. These are the default factory settings for virtually any router.
You require a wireless router because a wireless router empowers you to set-up a household network quickly, neatly, securely, along with room to include-on or expand. Consider just one common example: on any given night, or worse, on any given weekday morning, every family member from your kindergartner to the graduate student must print something. In the event the computers are not linked in a network, each impatient family member must wait their turn, inserting a CD or flash-drive in to the family’s main computer, and completing ryoutx the print settings. When you use your router to connect each of the computers in your home, every one of them will easily hyperlink to the family’s printer with just one click.
Therefore, during night-before or day-of crunch times, each desperate family member puts his documents within the printer queue and lets the network solve the traffic problems while he or she gets ready for school or work. For about $50 (US), a wireless router purchases a great deal of stress relief for the whole family.
