How To Create A Wireless Computer Network

While living in a growing age of technology, having at least one computer in the home is just as common as having a refrigerator. Most homes today will have some sort of computer equipment for either personal use or business use. With today's wireless-equipped laptops, a wireless router and, if you need one, a wireless adapter card, even the technically-challenged can create a network in a heartbeat. This discussion isn't about Bluetooth technology, nor does it relate to Macs.

The First Step

Workstations, printers, and laptops need a wireless adapter card installed. They're easy to install--sometimes they're already built in. If so, your equipment will say it's wireless network capable. If not, remove the case from your desktop computer, follow the adapter card's directions, and you'll easily identify the slot the card fits into.

On a laptop, the card slot is on one of the outside edges of the keyboard half. The card only fits in one way and installs in two seconds, no problem. Once the adapter is set into its slot, Windows' setup wizard steps you through installing the driver. You'll get the familiar message, "Windows found new hardware." Follow the prompts.

The current wireless protocol is 802.11. Wireless cards costs between $20 and $130. They can be found at any computer store or online outlet. The $20 card should be adequate. For a few dollars, weak-kneed users can get a pro to install the card and drivers.

Buying Your Wireless Router

Going in search of wireless routers at an office supply megastore, you'll find them from $39 and up. They come with 4 Ethernet ports plus a wireless access point. The Ethernet ports are sockets for setting up a "wired" network, but since you're going wireless, you won't use them. The wireless access point is the sort of radio thing on the router that talks to your computer to make the wireless connection. It doesn't require you to plug anything in.

Spending extra money buys more speed between router and computer, but for home use, on a small network, it's not really relevant. Usually, a router that transfers data at 100 megabits per second is fast enough. The package will tell you the speed.

Safeguard Your Stuff

By the way, an important fact about wireless routers is that they act as "firewalls." A firewall is software or hardware that prevents hackers from hacking into your system. The router puts an extra layer of security between you and them.

Some people claim the protection is negligible but a techie friend of this writer, with every piece of security known to man, tried to hack my network to demonstrate how feeble the router's protection was. He said, "In 10 minutes, I'll have your data." Three hours later, cussing a blue streak, he threw in the towel. Good security.

Wireless - Continued

To install the router, rely on manufacturer's directions. All routers are slightly different. For example, you'll plug your basic Netgear router into an electrical outlet, go back to your computer and navigate to Control Panel -- Network Connections. The wireless network connection icon should say you have succeeded and are connected. Your router is now talking to your computer. That's it.

Next, choose enable encryption, which is a way to assigning a security key, like a password, to the network's access to keep neighbors or anyone else from using your network. Gurus encourage everyone to do this. It's not difficult to figure out.

The manual directs you to type 192.168.0.1 into the address bar of Internet Explorer. Every user manual has a similar IP address (Web address) to an administrative program for each router. It's easy to follow menu selections on the page that comes us next. The help files are generally user-friendly and tech support is available by phone as well.

Hooking Up

With your new network set up, you add security cameras, printers, shared storage or anything else that can accept an adapter card or comes with network capability. Each item added -- printer, camera, computer -- needs wireless capability or a card and each shows up on the network with a name you give it - like, "new photo printer" or "Joe's laptop."

The best part of the whole set up is that the wireless signal goes through most walls, allowing you to work almost anywhere in your home, sans the yards of black spaghetti that used to connect you. Take your laptop n front of the fireplace. Recliner chair becomes your desk. Sip some hot buttered rum and be the envy of the neighborhood.
