It is dual band and has a rated speed up to 1200Mbps. (867Mbps at 5GHz, and 300Mbps at 2.4GHz.)
It also is a USB 3.0 so no need to worry about USB 2.0 bottlenecking.
The Ourlink is compatible with Windows XP, 7, and 10. We decided to do our testing on Windows 10.
Plugging in the dongle Windows 10 found it without having to install the drivers with the correct chipset. We installed the latest Drivers to be sure.
2.4GHz Wireless-N Test
The first test we did was on the 2.4GHz Wireless-N side of the dongle. The router is a Trendnet 80211ac router placed 10 feet away with a clear line of site.
The next test of the 2.4 GHz was computer-to-computer on our internal network. The computers didn’t have SSD drives so we copied to a USB 3.0 USB flash drive.
Iperf is a tool for network performance and measuring the throughput of a network. We set it up on our internal network.
5 GHz Wireless-AC Test
On the 5 GHz side we couldn’t get it to show up as a Wireless-AC dongle and it stayed as a Wireless-N.
We reinstalled the driver and restarted the computer and router and it still stayed on Wireless-N. We are still doing test on this to be sure it is not our Windows 10 machines or 802.11ac router.

The Glam Hobby Ourlink mini wireless USB adapter ran at almost a 100Mbps down in our test which is good for such a small dongle.
We did have problems connecting the 5GHz side to show up as 802.11ac unit. We are still testing it out to see if it is in our equipment or not.
There are much faster USB WiFi adapters but they also cost much more.
For the price it is a solid WiFi dongle and would be a good replacement for a broken laptops internal WiFi card or even as an upgrade.
As always be sure to read the reviews on Amazon or elsewhere to be sure it is a good fit for you.
