Time divisions are ~3 seconds. This transfer (downloading a picture)
bounced between 3.0 and 4.4 K (which I ass-ume means kilobytes?).

On longer transfers the pattern (sawtooth "wave") becomes very regular.

OK, you're talking about 9 seconds or so between each drop and rise,
that's not a protocol issue, it's way too long. It might be a
re-negotiation timing, or something your ISP is doing.

No. Maybe I wasn't clear: the time between the time divisions (vertical
lines) is about 3 seconds, so it's about a second between each drop
and rise. The display updates about once a second. (3 samples/time div.)
