How to Setup a Network

A network is a vast collection of hardware and software units that are able to communicate with each other over a certain amount of space. Networks can range in size from several rooms, as can be found in a home, to many different buildings, which can be found in large infrastructures such as corporations. A network may include multiple computers, a modem, one or more wireless routers or access points, and a wide variety of other devices such as mobile devices, printers, scanners, and even satellite systems. More information about setting up specific types of networks can be found below.

Desktop Computers

Desktop computers are quickly fading as the primary computer for home users but are still widely used in offices and other types of businesses throughout the world. Desktop computers are usually connected to a network via an Ethernet cable that physically connects the computer to an access point. For this kind of network, the user needs to purchase a modem or access point that connects to the building’s phone or cable line. Internet service is, of course, a requirement. Once the service is setup for the building, the user simply runs an Ethernet cable from the access point to the desktop computer. Internet access should be immediate but may lag temporarily if the access point is still booting up. While this is the most common option for desktop computer networks, users are still able to setup a wireless connection if an external wireless adapter is connected to the computer and the access point includes a wireless router. For wireless desktop connections, the user will need to ensure that all proper drivers for the adapter are installed and that a wireless connection is enabled in Network Connections or Device Manager.

Laptop Computers

A network for laptop computers is often easier to setup than a desktop connection but may be slightly more expensive. All laptop computers have a wireless adapter built into the hardware that allows them to automatically access unsecured wireless networks. In order to setup a home or office network for laptops, however, the user must purchase both a modem and a wireless router. These two devices may be included as a single access point, however, and do not take up too much space. Setup is easier with a laptop as the user simply has to connect the router to the modem and ensure that a power supply is provided to both devices. Once the user has done this, the laptop should have Internet access.

Mobile Devices

Mobile devices are similar to laptop computers as they often have network adapters built into them. Mobile devices such as PDAs, smartphones, and some cameras can automatically connect to a wireless network that is in range. Users should be aware of the fact that a mobile device’s signal may change depending on how close the device is to the network’s access point. Mobile devices also have the option, however, of connecting to a wireless network provided by the user’s cell phone service. In this kind of network, Internet access is constant and is entirely dependent on the features of the individual service plan.

Printers/Scanners/Fax Machines

In addition to desktop computers, laptop computers, and mobile devices, networks may include accessory devices such as printers, scanners, and fax machines. These devices may be connected to a network via an Ethernet cable or via a wireless Internet connection if the device is equipped with a network adapter. Some accessory devices have built-in network adapters while others have USB ports in which an external network adapter could be installed.

Small Business Computer Network

A small business computer network is a network of computers and devices throughout an office building that are able to communicate with each other. Computers, printers, scanners, and other devices can all be a part of a computer network. A computer network is essential for a small business because the company will need to be able to keep track of every aspect of the business at all times and should be able to perform any task without leaving a specific location. This is not always required but it marks a milestone in which a company can know that it is performing at its best.

LAN

LAN, or Local Area Network, is a physical connection between computers and devices by means of an Ethernet cable. A LAN can be setup with minimal effort and can extend throughout an office or building. LAN generally has a good level of security because the only people accessing the network are the people within the network itself. With a LAN, users can run an Ethernet cable through a router or directly from the modem. LAN is efficient and reliable as it provides constant connection despite weather conditions or other events.

WLAN

A WLAN, or Wireless Local Area Network, is a wireless connection between computers and devices by means of a wireless router. A WLAN can also be setup with minimal effort but may be slightly more complicated than LAN for the inexperienced user. This is due to WLAN having more settings and control options that must be setup correctly before a wireless connection can be established. WLAN lacks the security of LAN because anyone within range of the wireless signal can pick it up. Users do have the option, however, of encrypting their wireless connection with a password or other security features. WLAN is decently stable but can be affected by weather conditions and objects that may block the wireless signal from reaching the computer in question. WLAN also requires more equipment than LAN as a wireless router is required and desktop computers will need to be fitted with a wireless adapter.

Cisco Small Business Pro SPA3102 Voice Gateway with Router

The Cisco Small Business Pro SPA3102 Voice Gateway with Router is excellent for small businesses because it includes both a voice gateway and a router in one device. The router will be needed for a wireless connection and the voice gateway can be used to make and receive calls over a VoIP network. VoIP is cheaper and more efficient to use than a standard telephone line and generally includes many features that aid the user in answering telephone calls and processing customer support applications. The device includes two Ethernet ports that can be connected to a computer or device via an Ethernet cable. The device, of course, also includes a separate Ethernet port so that it can be connected to a modem.
