Why You Need A Wireless Internet Card
Wireless internet cards are essential for getting your laptop or cell phone on WiFi (wireless fidelity) networks. Sadly, they can't also double as a credit card or library card, but if you need to get on WiFi, then that's what you need. You don't need wireless internet cards for traditional desktop computers, as you most likely have a modem and digital transceiver device already installed that acts like the card.
Pick A Card, Any Card
Well, almost any card. Wireless internet cards are also called PC cards, which may be easier to look up information for. You need to make sure the wireless internet card is 802.11b compatible (most of them are - that's the standard setting). Although you can get any brand, be sure they are compatible to your laptop and your platform (like Windows XP or Mac). You need to make sure they fit in your laptop or cell phone's card slot, too. Some wireless internet cards come with a mini antenna that can help make the signal stronger. These are great for cars.
It usually is best to get the wireless internet cards offered by your wireless internet service provider (for example, get Verizon PC cards if you subscribe to Verizon's wireless internet service). This way, you are guaranteed compatibility and a place to complain to in case things don't work out.
Just What Do They Do?
They'll give you a headache when you look up information about them on the web, I can guarantee that much. Put into layman's terms, wireless internet cards not only act as transmission receivers to help you find and get on the WiFi network, but also give your memory storage and input/output (I/O) capabilities. There are separate cards for digital cameras that look like but do not work as wireless internet cards.
Wireless internet cards need a sufficient amount of power in order to keep on running, so you need to be sure your cell phone or laptop battery is charged. If you start suddenly getting a lousy transmission, it may mean your battery is running down. For those worried about the environment, there are solar cell phone and laptop battery chargers available. For the rest, you usually stick the recharger apparatus into the wall socket at one end and the phone or laptop in the other.
Although they take a little while to get used to, with practice you'll be able to work the card as easily as any other gizmo you have lying around the home that we all take for granted.
