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.
