This is probably a long shot, but a long time ago, some
routers or cable modems that did Network Address Translation
had a problem with packet fragmentation.
The issue was that the NAT business would add a few
bytes to the packets, and if they were already up against
the MTU limit for the connection, they'd go over, and get
fragmented, but the cable modem wouldn't recognize the
packet fragments, so the connection would just hang,
and this was common for big file transfers.
This is my rather hazy memory of the problem, of course.
The solution was to reset the MTU of the network interface
to be smaller than the default 1500. Doing something
like "ifconfig <iface> mtu 1492" would fix it.
I haven't heard of anyone having this problem for many
years, but it's possible there's a jumbo-frame analog
of it that's gotten you. In any case, it's pretty easy
to lower the mtu and give it a try.
