TP-Link N150 Wireless High Gain USB Adapter (TL-WN722N)
The TP-Link WN722N is a notorious USB adapter that has been available for awhile and still going strong.
One of the things that makes it stand out is the wireless chipset it uses Atheros AR9271. This chipset allows for it to go into monitor mode which is necessary when Pen testing a WiFi signal.
For this reason it is widely uses in the Pen Tester community for doing wireless attacks.
It also has a 4dBi omni-directional antenna for improved coverage.
While still widely used it is only a 2.4GHz dongle and wont work in the new 5GHz frequency. Since most all router are dual band and work in both ranges this isn’t usually a problem.
It is a 802.11n adapter so it also doesn’t work with the new 802.11ac protocol and will default to Wireless-N speeds (150Mbps).
With that said for the price it is still a very popular unit and a nice upgrade over a built-in wireless or adding better distance to a device.
Reliable, low cost, durable, along with multi purpose use make it a unit worth looking at.
