network router is a small electronic device which simplifies the creation process electronic network home . The home router serves as the core or «centre» of the network to which computers, printers, and other devices can be connected. A network with a router helps you:

  • File sharing between computers
  • Sharing an Internet connection between computers
  • Share Printer
  • Connect your game console or other home entertainment equipment to the Internet.

Routers are not necessarily required to build a network. For example, you can connect two computers directly to each other only with cable (or in some cases without wires). Home routers provide convenience and ease of maintenance as your network grows.

Selecting a network router

You can choose from several types broadband routers . The two most common types in popular use are models WiFi 802.11ac and 802.11n . 802.11ac is a newer technology, but 802.11n routers can often do the job at an even lower cost, and even routers 802.11g over- still work for those on a tight budget.

Installing a network router

Network routers are powered by a regular household electrical outlet. When turned on, the lights (LEDs) mean that the device is working.

Network routers must be carefully configured upon first installation. Like computers and other devices on your home network, routers must be configured with IP addresses . Routers also offer additional (but highly recommended) functions security .

Routers contain built-in software for settings . You access this software through web browser on any computer connected to the router.

Connecting Computers to the Router

The main use of a network router involves file sharing (copying files) between multiple computers. Technically you don’t need a router to set up file sharing (or home network), but using a router makes things a lot easier, especially when three or more computers are involved.

Home routers provide connection points (called ports or «jacks») to connect computers using cables ethernet . Connect one end of the cable to the router and the other end to network adapter computer ethernet . Wireless routers also allow computers to connect using WiFi if your computer has a Wi-Fi network adapter.

Connecting an internet modem to a router

The ability of a network router to share your connection to Internet by throughout the residence is the key selling point of these boxes. Internet connection sharing can be set up without a router using alternative methods, but once again, having a router makes things a lot easier.

To use the router for Internet sharing, connect your Internet modem to the appropriate router connector for this purpose. Many network routers allow connect broadband modems by using cable USB or Ethernet cable . Several network routers even allow connect traditional modems for switched lines through serial cables to the built-in serial port .

Connecting the Printer to a Router

Sharing a single printer between multiple home computers is often desirable, but surprisingly difficult to achieve. Without a router, people connect their printer to one computer designated as the printer’s host. This host computer must be specially configured, and it must also be running whenever someone needs to use the printer. Transferring this responsibility from the host computer to the router makes it easier to set up the network and use the printer.

You can usually connect the printer to your router using a USB cable or a USB to Ethernet cable. As an alternative, wireless equipment print server also exists. Print server connects to the printer’s USB port and in turn, makes a Wi connection — Fi to the wireless router. Several routers have a built-in print server, providing a built-in parallel port for connecting a printer directly.

Newer printers have built-in WiFi radios, so it’s as easy as connecting the printer to a WiFi network. After that, the printer becomes available to all devices connected to the network.

Connecting home entertainment equipment to a router

Game consoles, TV boxes, and other home entertainment equipment can be connected to network routers. Networked home entertainment equipment with a router allows these devices easily reach the internet .

Wireless game adapters (also known as wireless bridges) allow you to connect to Wi-Fi, and USB-to-Ethernet cables allow you to cable connect to your router for this type of equipment.

Other Uses for a Network Router

Several other types of devices can be added to a network router for special applications. For example, CCTV Cameras can be connected to a router to view live video streams from any computer on your home network (or even remotely over the Internet). VoIP Analog Terminal Adapters (ATA) will often connect to routers to enable services the Internet- calls VoIP .

On a Wi-Fi network, routers can be connected to other devices (called range extenders or signal boosters) that increase the overall coverage (range) wireless signal . Some people do this to share their home network with a neighbor. Wireless routers can sometimes connect to each other for a similar purpose, but care must be taken to avoid conflicts or interference between the two devices.
