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.
