Περιγραφή:
If you search this device as "TP-Link TL-WN821N", validate that you're getting version 2 or 3. Newer revisions don't work.

To use Wi-Fi with Tehnoetic TET-N300 Wireless USB Adapter for GNU/Linux-libre in Trisquel, I installed the free firmware from the official Trisquel package open-ath9k-htc-firmware. It is included in both Trisquel 7 and Trisquel 6 updates repositories.

sudo apt install open-ath9k-htc-firmware
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:
sudo dpkg -i open-ath9k-htc-firmware.deb
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:
sudo cp htc_7010.fw /lib/firmware # check if this path exists
or
sudo cp htc_7010.fw /firmware # check if this path exists
