Packet loss may be a result of a bad connection, and can't always be detected with a normal ping.

ping 208.67.222.222 -l 40096 -n 20 or on linux it's -s 40096

This pings a special server that allows large ping traffic, and looks for packet loss on the line. I had had packet loss on a wired line that prevented some traffic from going round trip.
