Tried with Ubuntu 16.04 64-bit and Aircrack-ng. The one I got is version 4.1 and according to airmon-ng has an Atheros AR9485 chipset. Tried monitor mode. Works perfectly. Try airodump-ng. Works perfectly. Tries to inject packages with aireplay-ng --test. Works perfectly. I haven't tried any real penetration testing, but on the face of it this seems to work for what I need and I can do packet capture for 2.4GHz traffic on Linksys WiFi routers.
