RESOLVED - thanks! Here's my update:
Symptom: USB wireless adapter not detected after Trisquelizing Ubuntu from
14.04 -> Trisuel 7
Configuration: Lenovo Thinkpad x220
Trisquel 7 Belenos
Wireless N USB Adapter w/ External 5dBi Antenna (Atheros AR9271) from
Thinkpenguin
Issue: open-ath9k-htc-firmware package not installed
Resolution: Opened System Settings -> Synaptic Package Manager, searched for
"open-ath9k-htc-firmware" (without quotes), found, installed, and symptom
immediately resolved without rebooting or taking any other action.
Comment: Perhaps this firmware package, which would be required to use these
Respects-Your-Freedom Trisquel-compatible USB wireless devices, should be
included in the packages added by the Trisquelize.sh script? In any event,
big thanks to the commenter (who I noticed helped many other people with
related issues and at one point hosted this firmware package on a personal
website), to the writer of the Trisquelize.sh script, and to the Trisquel
community at large. ¡Un abrazo muy fuerte para todos!
