How to Choose the Right USB WiFi Adapter
There are multiple factors to consider when picking out the USB WiFi adapter you want to purchase. The key items you need to consider are the USB types, the Wireless Frequency, the item's size, and the internet speed it provides.
USB Type
Most commonly, the USB types that WiFi adapters use are type 2.0 and 3.0. These two options transfer data at different speeds, affecting the output of any device. Purchasing a WiFi adapter that has a lower USB type will limit effectiveness when compared to other products.
If you're using an older computer or laptop, you likely have USB type 2.0 ports. Using a USB type 3.0 adapter will limit the transfer speed for data to that of the devices. Optimally, an item using USB 3.0 will result in a faster connection.
Wireless Frequency
Most devices use either a 2.4GHz or 5Ghz frequency, with selected models offering dual support. Both options have beneficial and negative aspects worth considering. Ideally, if you're using the adapter on a laptop that moves around, the dual option is worth purchasing.
The 2.4GHz connection type is better at penetrating walls and should be used if you're struggling to get a WiFi connection in a large house. This frequency is commonly used, ensuring that any devices pick up the signal.
The 5GHz frequency is more stable, as there's less interference from the many devices using a 2.4GHz connection. Unfortunately, this option is quick to suffer from signal loss over long distances.

Sizing
The best USB WiFi adapters have various sizes that can become awkward if you're using them on laptops or computers. Models with antennas can feel large and bulky once you set the item up.
Alternatively, there are many options the size of a regular USB stick or smaller that you can quickly pocket when traveling. The smaller models without antennas are unlikely to pick up a WiFi connection across longer distances.
Speed
Each of the best USB WiFi adapters has a different internet speed rating. This variation is increased with more expensive options that can support speeds of up to 1300 megabits per second.
Lower end and cheaper devices can support speeds of as low as 150 megabits per second. As long as your adapter is better than your internet speed, you'll have no issues or throttling.

Review
With a high-speed transfer rate of 1300Mbs, the Netgear Nighthawk AC1900 is ideal for anyone with a fast internet connection. The dual-frequency ensures that you'll almost always have a reliable connection to your WiFi. As it uses USB type 3.0, older computers with the previous version of the ports won't get the highest speeds offered by the product.

CONS
Specs
USB Version: USB 3.0
Data Link Protocol: Ethernet
Windows Compatible: Yes
Mac Compatible: Yes
Review
As an honorable mention, the Net-Dyn AC1200 is not the best on this list unless you're using an older computer. The item runs on Windows versions as old as Windows 2000, an operating system that is now 21 years old.

The Net-Dyn AC1200 is an honorable mention as it provides plenty of useful features but struggles with connection over longer distances. The item's design resembles a USB thumb drive that is easy to pocket or adds onto a PC.
The transfer rate is decent at 1000 megabits and works on Windows versions from 2000 and up.
What Does a USB WiFi Adapter Do and Why Do You Need One?
A USB WiFi adapter is a useful item for any laptop or computer that operates on a wireless network.
What it Does
A USB WiFi adapter is a USB-connected device that receives and transmits a wireless network signal to your computer or laptop. You can use these products to extend the strength of your internet signal, decreasing lag within moments.
Extra Range
A USB WiFi adapter is an easy way to get a better signal when you're away from a modem. Many products come with an antenna that helps them pick up a more robust connection, resulting in less lag or failure to load webpages.
Specific models include a dual receiver that picks up both 2.4GHz and 5GHz frequencies, making it easy to receive a WiFi signal. This dual-frequency option dramatically improves the range and reliability of any internet connection.
Quick and Easy to Install
The benefit of the item being a USB device is the ease of installation for the device. Most of the best USB network adapters are ready to go from the moment you plug them into your computer. These products can come with cradles that allow you to position them in limited space easily.

How Do USB WiFi Adapters Compare to Other Devices?
A USB WiFi adapter isn't the only way to connect your computer to the internet. You can use a WiFi card or a PCI-e WiFi adapter. These options have their benefits and downfalls when compared to a USB network adapter device.
PCI-e WiFi Card vs USB WiFi Adapter
When comparing prices, the PCI-e WiFi card can cost slightly more and requires an empty slot on your computer's motherboard. However, while the installation is simple, you may damage parts of the PC that are sensitive to static.
Once installed, the part is superior in speed and network strength to a USB WiFi adapter. However, USB network adapters are a more comfortable option to install and replace, as you simply plug them into a USB port when needed.
Additionally, the device's antennas aren't stuck within a metal case that interferes with signal strength. The USB option often includes a WiFi extender that increases how far away from your modem you can get.
USB WiFi Adapter vs PCI-e Onboard WiFi
Onboard WiFI is provided directly from your motherboard, requiring no extra part to your computer. The onboard option far exceeds a USB device's latency, making it a more reliable method for lag-free use.
However, the onboard system will eventually fall out of date and need either a WiFi card or USB adapter. The option is also more expensive compared to a USB WiFi adapter.

Pros and Cons of USB WiFi Adapters
There are multiple reasons a USB WiFi adapter is a superb choice and a few reasons that may seem less inviting.
Ease of Installation
Unlike with a card or onboard WiFi connectivity, you can easily install a USB network adapter. All you need to do is plug the device into your computer's port, and it will run. Occasionally you'll need to install the driver beforehand if your PC uses an older operating system.
Extends Range
Aside from merely picking up a network connection, USB WiFi adapters can improve the connection's strength. This feature is most common among models that include an antenna and dual-frequency support. The dual-frequency and antenna help to pick up signals better as you move away from your modem.
Weaker Than Alternatives
A USB WiFi adapter is ultimately the worst of all options when it comes to durability, efficiency, and latency. The part stays on the outside of your computer, making it easy to break off and damage. Each piece needs to be replaced within four years as they often die out before reaching that lifetime.
USB WiFi adapters also have a lower-strength antenna and components, making them worse at receiving signal than a motherboard or insertable card option.
