For me, it always stops at 766 packets received.

--- localhost ping statistics ---
47742 packets transmitted, 766 packets received, 98% packet loss
round-trip min/avg/max = 0.7/227.6/422.3 ms

--- localhost ping statistics ---
8166 packets transmitted, 766 packets received, 90% packet loss
round-trip min/avg/max = 0.7/158.6/285.0 ms

--- localhost ping statistics ---
56121 packets transmitted, 766 packets received, 98% packet loss
round-trip min/avg/max = 0.7/251.0/491.2 ms

I refuse to floodping any other site on my network because that would
surely be considered abuse.

Does it always stop at 781 for you? Maybe this is a _feature_. :-)

Perhaps this is related to that "too many network errors problem" as
ifconfig gives me this:

Over 22 million errors? I wish I knew what was going on here... :(
