USB wireless internet cards are as small as many other USB products, and just as light. You can expect most to be small enough to fit in your pocket with ease. This tends to lean them towards being used in scenarios that would favor minimal burden in bulk or weight, such as using a smaller computer while traveling.

The fact that these products are USB-based is a large part of what makes them so intuitive and quick to use. Almost all computers have multiple ports for USB devices, and most of these are placed in prominent, easy to reach locations. There's rarely a circumstance where you'll run out of these ports or be unable to reach them. Such unusual circumstances would be caused only be using a multitude of USB peripherals, or by using a very old model of computer.

You may see numbers mentioned in descriptions of USB, either for these products or when learning more about your computer. These numbers refer to the USB version. The bulk of wireless cards that use USB ports will work with all versions, so it's not a huge issue. However, you will typically get the best results and faster connection speed from an up to date version.

One common bonus often included with these products is a cord to extend the reach of your USB port. These are unnecessary for most people. But in situations where the port is difficult to access for some reason, a cord will allow you to lengthen the range easily and keep your overall setup accessible and fast.

USB devices have a distinct tendency towards not requiring external power, and this also applies to USB wireless internet products. The minimal amount of power required is taken from your computer, and this process has no negative side effects. In other words, all you need to make the wireless card work is the wireless card itself... and, of course, a computer to plug it into.

Any given card may or may not be compatible with your particular computer configuration. This is mostly just a matter of which operating system you run. **USB wireless cards** will usually support many versions of Windows, and some may also offer Macintosh support. Additionally, you should be aware of potential registry, settings, and general program use issues in a model before you buy it. A good wireless card won't have these problems, but not all of them are good!

If you're concerned about keeping your information private through a well-defended network, the average wireless connection just won't do. But some models of wireless cards offer particular support for making the establishment of secure connections very easy. If you need that kind of privacy, look for the ones that give it to you. You should be able to get it without paying significantly more for the feature.

When compared to other function-enhancing USB devices, like the popular **laptop tv tuners**, wireless USB port enablers don't cost that much. In fact, by almost anyone's standards, the least expensive models are eminently affordable. Would you say no to wireless internet anywhere for twenty dollars? Hopefully not. And, of course, if you need something faster or generally more packed with features, there are also thirty, forty, and even eighty dollar models on the market.
