A Simple Guide to Wireless Networking
Most folks want that laptop for work, school, or college. Most laptops these days are Wi-Fi enabled. That means that they have the wireless hardware and software built into the computer. To the average consumer, wireless is a form of magic. You turn it on and it works, right? Not always. Understanding the basics to wireless will help avoid frustration and headaches.
First, before we get into the basics of wireless networking, I have a few opinions to express.
It seems that everybody wants to go wireless with their laptops and desktop PCs. Wireless for laptops makes sense, since they get moved around between work and home and points in between. You can always connect using the Wi-Fi network at work or steal bandwidth from someone else. There are hotspots all over. There are ethical questions involved with borrowing?your neighbors signal. Let your conscience be your guide.
Wireless for desktops is an open subject. Since most of us usually set our desktops up on our home or office workstations, they tend not to move around. The only benefit of having a wireless desktop is that you dont have the expense and trouble of running Ethernet cable around your house. If you are not a DYIer, an Ethernet cable installation is an extra outlay. If youre lucky, your present PC is only a few feet away from your Broadband Modem. I personally prefer to have all my stationary PCs hooked up with Cat 5 Ethernet cables. That way I dont load up the wireless bandwidth on the router. Well talk more on bandwidth later.
There are hardware requirements to wireless networking. These are the things you need to communicate.
At home you need:
- (1) a Broadband internet connection (Cable or DSL modem),
- (2) a router to broadcast the wireless signal,
- (3) a wireless enabled computer.
The Broadband internet connection gear should already be present. Thats the Cable or DSL Modem that your Internet Service Provider installed when you got their service. Its connected to the Cable or DSL filter connection coming from your wall. The Modem has two connectors as a rule. One for the Cable or DSL data into the Modem, and one RJ45 connector you probably have connected to the computer you have in service now.
Youll need to unplug the Ethernet cable between the computer and the Modem. Reconnect that cable to your wireless router. It goes into a RJ45 connector usually labeled WAN?for Wide Area Network. The only other connection you will need to make is to connect another Ethernet cable between from one of the wired ports on the back of the router to your PC. There are usually 4 of them. Any one will do to reconnect your existing PC so its on the network. The existing PC will get its internet connection through this port. Your routers default settings should allow you to start connecting to your Wi-Fi enabled computers.
If all the cables are correctly placed, you should now be able to get on the Internet from you existing computers and your wireless computers.
Some quick notes of interest:
- (A) Your Wi-Fi router is transmitting and receiving in the 2.4MHZ range. So are your Wi-Fi enabled computers. This is the same frequency range of a number of cordless telephones. You may have interference on your cordless phones once the Wi-Fi network is installed. If this occurs youll need to get 5.8 MHZ phones or put up with the noise.
- (B) One of the most common questions I get is ?strong>I bought a wireless laptop and I cant get on the internet. Why not??If your wireless router is installed properly, then your wireless laptop may need configuration. Go to your Network Places or Network Neighborhood for a wizard to help you set up your computer for wireless.
- (C) Bandwidth is the volume of traffic you can sustain through your network. The more devices using the Wi-Fi network, the slower the network uploads/downloads will be.
