Tehnoetic TET-N150HGA is our own branding for the TP-Link TL-WN722N, with a guarantee that the TET-N150HGA version ships with the Atheros AR9271 chipset that uses free software drivers and firmware; we can make no guarantees that other versions of the TL-WN722N will ship with the same chipset.

With the Tehnoetic N150 High Gain Antenna Wireless USB Adapter for GNU/Linux-libre you can connect to Wi-Fi networks using exclusively free software. With its external antenna and internal antenna having 1x2:1 MIMO configuration, it has a wider range and reaches speeds up to 150Mbps. Also, the detachable external antenna can be replaced with a higer gain or directional one. You might also be interested in the Tehnoetic N150 Mini, the Tehnoetic N300, and the Tehnoetic N300 Dual Band Wireless USB adapters.

The Tehnoetic N150HGA is based on the Atheros AR9271 integrated circuit. It works with the free driver ath9k_htc (GNU GPL v2) and the free firmware for ath9k_htc (Clear BSD). Thus you can use it with a completely free GNU/Linux distribution, which has the kernel Linux-libre, clean of the nonfree blobs from Linux. Using the latest versions of the kernel (3.0 or later), the adapter works out of the box when plugging it on USB, and you don't have to manually install the firmware anymore.

Because the firmware is free, you can study it and check what exactly it's doing. Moreover, you can modify the way the adapter works, so it can be an important resource for educational experiments or for your business. With the Tehnoetic N150HGA Wireless USB  adapter, your are in control of your own computer for connecting to Wi-Fi networks too.

Buy it for your laptop! You have a laptop with a Wi-Fi card which doesn't work with free software or it's broken. Plug the Tehnoetic N150HGA adapter in an USB port and connect to Internet.

Buy it for your desktop! You have a dektop computer and want to get rid of the wires or get better signal. Plug the Tehnoetic N150HGA adapter in an USB port and connect to Internet. For even better signal, you can use it with an antenna extension cable. You get rid of the wire and you continue to use free software.

Buy it for your development board! You have a development board or an embedded device without an integrated circuit for connecting to Wi-Fi networks, with one which doesn't work with free software or simply want to have better signal. Plug the Tehnoetic N150HGA adapter in an USB port and control your device remotely (also through Internet). You can thus make it a router or media center.
