The USB WiFi Adapter Guide

Before you can go out and buy a USB wireless adapter, you have to understand some of the idioms which are used to describe them. Product descriptions for these devices are often jammed full of terminology which some people may not understand. With that in mind, we’ve decided to write this ultimate USB WiFi adapter guide to help users through the process.

802.11 Standards

The first number that you’ll notice when you start looking for wireless adapters is the 802.11 standard. This standard is how modern wireless adapters communicate with routers. After the 802.11standard designation is a letter such a g or n. Therefore, some listings will list a wireless adapter as having an 802.11g or 802.11n designation.

In 2007, the 802.11n was introduced, and it replaced the 802.11g standard which was introduced in 2003. The 802.11n standard was designed to have a theoretical download speed of 300 Mbps. I say theoretical because a variety of factors can affect the speed of an adapter, so it’s really just an estimate.

To avoid going into complicated details, I’ll say just one thing about this standard. The latest standard is the 802.11ac, and it has a theoretical speed of about 720 Mbps. Once again, this is only theoretical, and a lot of things can affect download speeds including network congestion, hardware conflicts and physical obstructions such as walls or floors. That always has to be considered.

Now, that we’ve talked about the last two latest standards, it’s time to mention the fact that these protocols are backward compatible and will work with older standards. For example, if a person’s adapter is 802.11ac, and their router uses 802.11g, then the adapter will connect to it, but it will do it at the slower speed. While there are still a lot of devices that use the 802.11n standard, the 802.11ac standard is better. Not only because it generates better speed but because it has a greater distance than the 802.11n standard.

The 2.4 GHz Versus 5 GHz

Nowadays, routers and wireless accessories use radio signals based on either the 2.4 GHz or 5.0 GHz frequencies. While these two terms are often indiscriminately printed all over the packaging of all kinds of different wireless devices, people often don’t understand their meaning.

5 GHz frequencies are faster than 2.4 GHz frequencies, but not every router operates at the 5.0 GHz frequency. This frequency is also less likely to have interference on it because most consumer devices are still operating in the 2.4 GHz range. However, 2.4 GHz frequencies travel further than 5.0 GHz ones. Why? Because shorter frequencies travel farther than higher frequencies.

So, which one is better? Well, that really depends on the needs of the user. Technically, 5.0 GHz offers less interference from other devices and supports higher download speeds, so if the user isn’t too far from the router and has a router that supports the 5.0 GHz frequency, then that’s the one to get. However, if the router only supports 2.4 GHz or the user is located far away from the router than 2.4 GHz is the way to go.


When buying a USB WiFi adapter, it’s important for the user to determine if the adapter is compatible with his or her personal computer. Most of the good adapters manufactured nowadays are capable of being used on Windows and MAC machines, but it’s always a good idea to check.

Antenna Gain

While it’s beyond the scope of this guide to explain electrical engineering, it is important to consider the strength of the antenna found on a prospective wireless adapter. This is a bit simplistic, but the strength of an antenna is usually expressed by the dBi value. For most home consumers, a larger dBi value usually equates to a greater range.


While most USB wireless dongles are plug-and-play compatible, which means they will be automatically set up by the computer, that isn’t the case with all of them. Some of these devices need to have drivers installed before they can be used. There are some devices which provide these drivers on a CD but others require the user to download the drivers off the Internet.

It’s also important that some of the devices which require drivers require that these drivers are installed before the unit is plugged into the computer. If this isn’t done, then these devices may not work properly or even work at all.

Additional USB Wireless Adapter Tips

Now that we’ve covered some of the basic terminology and how it pertains to purchasing a USB wireless adapter, it’s now time to check out a few additional things a person needs to consider before purchasing one of these devices.

Check for free USB ports—It’s important for a person to consider if they have a USB port available for their adapter. While it may seem like it would be obvious that you need a free USB port to plug in one of these adapters, it’s, unfortunately, something that’s often overlooked. If a user doesn’t have a free USB port, they can always consider buying a powered USB hub and plugging the rest of their devices into it to free up a port.

Consider dongle placement—Another thing prospective buyers need to consider is the position of the USB ports on their computer. On some computers, plugging a wireless adapter will take up two slots because the USB ports are positioned so close together. Also, many laptops place their USB ports on the side, so it may make the USB wireless dongle susceptible to getting hit or broken.

Consider a removable antenna—While some people will never need to buy an adapter with a larger antenna, some people may not be able to do without it. Larger antennas are necessary for individuals who need to get a little bit of extra range out of the wireless connection or if there are a lot of obstacles between the computer and the router.

In Conclusion

While it may seem overwhelming or difficult for a person to find the right USB WiFi adapter for their particular needs, that doesn’t have to be the case. By taking a few moments to consider speed, features, compatibility and whether there’s a free USB port available, consumers can find a device that upgrades their Internet connection in ways they never thought were possible.
