differences in the entry: Description
If you search this device as "TP-Link TL-WN821N", validate that you're getting version [a]https://h-node.org/wifi/view/en/253/Atheros-Communications-Inc-TP-Link-TL-WN821N-v2--Atheros-AR9001U--2-NG-|2[/a] or 3.

[p]To use Wi-Fi with [a]https://tehnoetic.com/tet-n300|Tehnoetic TET-N300 Wireless USB Adapter for GNU/Linux-libre[/a] 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_7010.fw /lib/firmware # check if this path exists
[/code]
or
[code]
sudo cp htc_7010.fw /firmware # check if this path exists
[/code]
