USB WiFi adapters work very well at connecting a desktop, laptop, or other electronics wirelessly to a router.
This makes it easy to set up a wireless signal and get online.
There are many USB WiFi dongles available with our favorite 2021 options below, along with full reviews, compatibility, and speed.
There have been some changes to WiFi with a new naming scheme and new protocol released.
WiFi Protocols New Naming Scheme and Speeds 2021
|Protocol||Old Name||New Name||Year Introduced||Theoretical Speeds|
|802.11n||Wireless-N||WiFi 4||2007||300 Mbps|
There is also a new protocol called Wireless-AX WiFi 6 (802.11ax) that has the fastest wireless speeds.
Currently, there is no Wireless-AX WiFi 6 USB adapter as it is still new and not widely used yet.
We are on the lookout for a Wireless-AX wireless USB adapter and will update this post when one is released.
Having the newest wireless protocols doesn’t automatically make an adapter the best.
Build quality, speed, range, antenna size, backward compatibility, and more all need to be considered.
Below we list the best WiFi USB adapters currently available along with reviews to see if one is a good pick for you.
As always be sure to read the reviews on Amazon, here, elsewhere to be sure a unit is a good fit for your set up.

The Alfa AWUS036ACH is an 802.11AC dongle built for fast WiFi speeds and distance.
During our test, it worked with Windows 10 basically plug-and-play with some impressive wireless speeds, 213Mbps Download, and 21Mbps Upload.
Alfa USB adapters are widely used in the Pen Testing community for their strong Chipsets and screw on antennas that can be easily changed out for larger ones.
If you need better WiFi coverage along with fast speeds this is a good adapter to get.
This unit from Glam Hobby called Ourlink is a small low-cost 802.11ac dual-band dongle
In our test it worked well with Windows 10 and ran at a solid 100Mbps download speed.
Even though it did well for a low-cost dongle we could not get it to show up as a Wireless-AC unit and only Wireless-N. (Update: New Drivers have solved this problem)
The TP-LINK Archer T1U is another entry-level 802.11ac USB adapter.
It is a USB 2.0 dongle that will bottleneck if your computer has 3.0 built-in.
There is no support for older routers and only works in the new 5 GHz band.
Since it only works in the 5 GHz frequency unless you know you have a Dual Band router it may be best to go with a Dual Band adapter which will work with any wireless setup.
The TP-Link Archer T2UH USB Adapter is also an entry-level 802.11ac adapter.
In our test it worked well enough although not as good as we expected from TP-Link, but is compatible with Macs and Window machines.
The downside was it is only a USB 2.0 dongle which will bottleneck at 480Mbps.
TP-Link is a known manufacturer of wireless products. For those looking for a Name Brand WiFi dongle, it is a good one to go with.
This adapter from Panda is a Wireless-N 2.4GHz network adapter with a screw-on/off antenna that gives it good range.
It is only a 2.4 GHz Wireless-N dongle so the speeds are not the best but it works well for those who need more distance from their WiFi.
The Edimax EW-7811Un is a small and convenient wireless dongle. It is an 802.11n 2.4 GHz adapter.
This is not a dongle built for speed or distance since there is no large antenna. If you are looking for a quick reliable cheap WiFi adapter this one will get you online. Just don’t expect it to do wonders.
The ANEWKODI is a low-cost but reliable dual-band dongle.
It uses the new 802.11ac protocol and has a small antenna to give it a boost in coverage.
It is a good low-cost unit that will give coverage a small boost and get you online quick and easy.
The USB Novel 600CU is a small nano-sized wireless USB adapter that runs the 802.11ac WiFi protocol.
Its small size would make a good fit to upgrade a laptop or add wireless to a desktop.
While testing the unit gave some good results on the 5GHz frequency of 218Mbps Download, and 21Mbps Upload.
If you are looking for a fast wireless dongle than the ASUS USB-AC68 is worth a look.
While it is possibly the fastest it unfortunately also cost the most. Many will not require such a high cost USB adapter and can use a low-cost alternative. Another downside is no Linux support.

Wireless USB Adapter Buyers Guide
When buying a USB network adapter knowing a few things will go a long way to fit your setup.
Finding a USB network adapter that works best for the desktop, laptop, tablet, and router you use is the main objective.
So let’s look at the things that are important to know with WiFi today.
2.4GHz vs 5GHz Frequencies and Distance
2.4GHz was the frequency used for WiFi until 2013 when the 5GHz band was opened up for wireless devices.
The thing is the higher the frequency the less distance wireless signals can reliably travel.
So a dongle using the old 2.4GHz will transmit and receive farther than the newer 5GHz dongles.
So why use the 5GHz band?
Simply put there are too many devices talking in the 2.4GHz frequency.
It has become overcrowded which slows everyone down trying to get a signal through.
When a WiFi signal packet collides with another packet it must be resent which slows the network down.
While the 5GHz band is not able to send a signal as far as 2.4GHz it is not crowded and relatively unused.
If you live in a crowded city using a 5GHz WiFi adapter is likely your best option.
If you need a signal from a distance and live outside a city with few if any neighbors a 2.4GHz dongle is likely your best option.
802.11 WiFi Protocols
802.11 is what sets the standards for manufactures and device manufaturers to create their products that all talk together.
Here are the main ones to know.
- Wireless-N WiFi 4
- Wireless-AC WiFi 5
- Wireless-AX WiFi 6
The WiFi Alliance now has a new naming system for wireless protocols.
This includes Wireless-N now called WiFi 4, Wireless-AC is now called WiFi 5, and Wireless-AX is now called WiFi 6.
The new naming scheme is simply a way for users to understand wireless protocols better.
Most WiFi USB adapters are 802.11n also called Wireless-N. Wireless-N can work in both the 2.4GHz and 5GHz frequency ranges.
Dongles that work in both 2.4GHz and 5GHz ranges are called Dual Band.
Dual Band is ideal for backward compatibility with older devices.
Wireless-AC WiFi 5 (802.11ac) was introduce in 2013 and is much faster than Wireless-N.
Wireless-AC WiFi 5 only works in the 5GHz range which doesn’t travel as far as 2.4GHz but has much higher speeds.
The new Wireless-AX WiFi 6 is the newest WiFi protocol with the fastest wireless speeds yet.
Like Wireless-AC WiFi 5 only works in the 5GHz range.
Currently, there are no Wireless-AX WiFi 5 (802.11ax) WiFi adapter being sold.
Wireless USB Adapter and Antennas
Internal antennas are good at staying low profile but will not transmit as far as an external antenna.
Adapters that come with an external antenna often use an SMA connector that will allow for easy-screw-on attachments of different sized antennas. This allows for very cheap solutions to connectivity and distance issues.
An antennas size is valued by its dBi number value, for example a 9 dBi antenna is bigger than a 5 dBi antenna.
How To Install and Setup USB Wireless Adapter
- Insert the USB adapter into a USB port.
- A PC will usually install the Drivers automatically.
- If the Drivers do not install a CD with the Drivers is usually included.
- If there is no Driver CD, search online for the manufacture website to download and install them.
- Once the Drivers are installed you should be able to connect to a WiFi signal
If you are unsure which USB network adapter will work in your wireless network be sure to get a dual-band dongle as they will work in almost any network.
Dual-band will work with both the older 2.4 GHz and new 5 GHz frequencies.
Also, be sure your operating system is supported by the dongle and the drivers available.
For example, a Windows 10 PC will need Win 10 Drivers.
The WiFi protocols will also matter since new protocols have more security and speed compared to older ones.
