These two should work with any network interface (watch for error and dropped frames): netstat -ni 1 watch -n1 "ip -s a l" Wireless specifics (signal strength, noise ratio, etc) are better viewed by airodump-ng from aircrack-ng package, although stock iw or iwconfig should do too. Also, consider wrapping a sheet of tin foil around USB WiFi dongle, transforming stock omni-directional antenna to uni-directional. Reco
