Setting up a Network — Wired or Wireless?

November 19th, 2009



To Wire or Not to Wire

Wireless networks are en vogue, but your installation won’t be successful unless you chose the right type of network and set it up properly. Wired networks require that each computer be connected via a wire to a central location, called a switch or hub. This often involves installing cables through walls and ceilings and can present a challenge for anyone.


If the computers in your home or office are all within 500 feet of each other, a wireless network might be for you. A wireless network has no cables. It can connect computers on different floors of a building or even across the street. Aside from the obvious benefit of not having wires, wireless networks are more convenient since the setup, configuration, and reconfiguration can often be done within minutes, without extensive planning.


Wireless networks, however, are not as fast as wired networks. If you play computer games or want to view streaming video or other high-speed multimedia, a wireless network might not have enough capacity. But, if you just want to check e-mail and view web pages, a wireless network is a good choice. To install a wireless network, you need a Wireless Access Point and a wireless network card for each computer. You will need to buy a wireless network card for each desktop computer, although most newer laptops come equipped with one.


Security is not a large concern in a wired network, since someone would have to physically connect to a wired network to break in. In wireless networks, a car parked outside with a laptop could easily connect to your network if you don’t have proper security in place. To prevent this from happening, encrypt your wireless network connections, or set a password to access the network, or do both.

Do It Yourself or Call a Professional?

If you decide to use a wired network, consider whether you will install it yourself or hire a professional. If you have a small number of computers that are all situated very close to one another, you may be able to buy pre-assembled network cables and connect them yourself. If you need to wire multiple floors and lay wire through ceilings and walls, you need a professional installation. If you go this route, it is best to begin with a floor plan of your office or home, determine what your current needs are, and consider how the network design can be adapted to future needs. A professional installer should be familiar with EIA/TIA standards, local wiring and electrical codes, and making custom cables. Network cabling professionals are often judged by the neatness of their work, because sloppy cabling is more apt to deteriorate over time, harder to manage, and poses more of a fire risk.


Having a wireless network or a wired network is not mutually exclusive. Many small offices have a wired network in addition to one or more wireless networks, depending on their needs. Wireless networks are continuing to get faster, more secure, and less expensive. Wired networks will continue to coexist with wireless networks, often in the same homes and offices.

Benefits Of A Laptop Computer For Home Business

November 13th, 2009



Laptops are often the first type of computer that anxious buyers look into. They are small and slick looking usualy light machines for the most part. Laptop computers have all the ability and function of a full desktop on a smaller scale. Their size limit’s the amount of memory they can handle but laptop computers are still very powerful machines. Today laptops can be just as useful as desktop pc’s. In today’s busy society they fit into most people’s daily lifestyles perfectly for three reasons. The top two reasons that most people use laptop computers are mobility and space efficiency. However, the benefits certainly don’t stop there.

Mobility

In today’s technology-reliant world having a computer is pretty much mandatory. Whether your laptop computer is a brand new Compaq Presario or a Dell, chances are you carry it with youand use it constantly. The mobility of laptops and notebooks allows for their users to have their important files at hand as well as the means to update those files and copy them for others to use. With the advent of wireless technology a Compaq laptop combined with Compaq wireless makes for an unstoppable media and work outlet. A flashdrive can make file transfers easy and will support the mobillity of your laptop.

This ease of mobility will serve for many different people, including those that own their own business. Business people will love the appeal of being able to work on commutes and trips. Students will have the advantage of being able to take notes in class as well as have their personal computer with them for weekend jaunts to the homestead. People who work at home doing telecommuting jobs will be able to leave the house for a cup of coffee and a change of scenery without losing any work time.

Space Efficient

Laptop computers are much smaller than a desktop computer. This being the case it is perfect for the person who does not have much room or just wants a less cluttered working area than the desktop affords. College students who live in dorms benefit greatly from this as they have limited work space and often need to use desk space for other purposes than schoolwork. People who live in smaller apartments or homes can also benefit from the small size as any space that is available can become a work space. The small size is also a plus in shared spaces as it makes it easy to store. It can be set on a shelf when not in use leaving space for tables and desks to be repurposed. Also it can very easily unhooked and locked up for safe keeping when not needed for work or play. Although a laptop may not be ideal for everyone as they are often the right choice for a variety of people. From college students, to busy professionals, to work at home moms the laptop computer can ecome an invaluable asset to their everyday lives. It can certainly make your home business easier to operate if you have a handy laptop to take everywhere you go!

Setting up a Wireless Network

October 16th, 2009



Some people see the task of setting up a wireless network within their home as a daunting task but it really does not need to be. In our present generation we are surrounded by many wireless possibilities. This is ok as long as we protect ourselves and familiarize ourselves with how it all works.

First of all you need to decide how you want your network setup and what you will need to accomplish this. In most cases a home will have one desktop computer and then one or more other computers located elsewhere within the house. These other computers may be other desktops or mobile laptops which doesn’t really matter except that you will need to find the appropriate wireless adapter for these computers. A desktop will need either a wireless PCI adapter or USB adapter while a laptop can use a PCMCIA adapter card or USB adapter. Most new laptops come with wireless already built into the system so you may want to verify that before buying an adapter. Then you need to also get a wireless router. It is preferrable if you purchase the router and the adapter from the same manufacturer but it is not a necessity. As long as they are both the same technology they should work together. 802.11g is the most commonly used signal. The wireless router works as a base station that transmits your internet signal wirelessly. Your wireless adapters connect your computers to the router with that signal.

First of all you should unplug your broadband modem. This may be DSL, Cable or FIOS. Also your router should be unplugged. Now connect a network cable from the modem to the Internet, WAN or WLAN port on the back of the router. Plug in the modem and turn it on. Wait a few minutes to make sure that it is connected with the internet. Then plug in and turn on the router. The lights on the front of the router should come on after about a minute indicating that the modem is connected. Now turn on the computer if it is not already turned on. Most people will plug the main computer directly into the router and make the others wireless thus eliminating an unneeded wireless adapter.

So now you will plug a network cable from one of the LAN ports on the router directly to the LAN port on the main computer. Windows XP will recognize an internet connection and give you a popup message with this indication. Next you will open your internet browser ( Internet Explorer or Firefox ) and type in the address that came with the documentation with your router. You may be prompted for the default password. The page will show your router’s configuration. From here you can enter in a Wireless Network Name which is called the SSID. Make sure that this name is unique for your own protection. Also set the WPA or WEP which should also be a unique type of word.

This is a passphrase protection which you will not have to remember. Then finally an administrators password. Make sure that you do not forget this password because you will need it if you ever want to change anything. Now that the router is setup we will move on to the adapters. Plug in the adapter appropriately on your other computer or computers and Windows will recognize it and show that there is a wireless connection device. Note that a desktop must be shut off when installing a PCI adapter. At this time Windows may prompt you to install any software that came with the adapter. Once that has been done, right click on the Wireless Network Icon in the bottom right hand corner of your Windows screen. It will say View Available Wireless Networks. Locate your wireless network name and click connect. Your wireless network should now be setup.
