[p]To get my TP-LINK TL-WN722N to work on Trisquel 6.0 Toutatis, I installed the latest Linux-libre from jxself's Freesh repository and installed the free software open-ath9k-htc firmware package (source is available [a]https://github.com/qca/open-ath9k-htc-firmware | here[/a]). [/p]

[p]To use Wi-Fi with [a]https://tehnoetic.com/adapters/tet-n150hga|Tehnoetic TET-N150HGA High Gain Antenna[/a] and FSF-certified [a]https://tehnoetic.com/tehnoetic-wireless-adapter-gnu-linux-libre-tet-n150|TET-N150 Mini[/a] adapters in Trisquel, I installed the free firmware from the official Trisquel package open-ath9k-htc-firmware. It is included in both [a]http://packages.trisquel.info/belenos/kernel/open-ath9k-htc-firmware | Trisquel 7[/a] and [a]http://packages.trisquel.info/en/source/toutatis-updates/open-ath9k-htc-firmware | Trisquel 6 updates[/a] repositories.[/p]
[code]
sudo apt install open-ath9k-htc-firmware
[/code]

or, if not running Trisquel and your free deb-based distribution doesn't package the free firmware, download the Trisquel package from a mirror and install the Trisquel package:

[code]
sudo dpkg -i open-ath9k-htc-firmware.deb
[/code]

or, for other free distributions that don't package the free firmware, unpack the deb archive and copy the free firmware to the canonical location:
[code]
sudo cp htc_9271.fw /lib/firmware # check if this path exists
[/code]

or
[code]
sudo cp htc_9271.fw /firmware # check if this path exists
[/code]
