I might be reading the results incorrectly, but I think the ping
results you have posted indicate 0% packet loss (11 packets
transmitted, 11 received in both cases). What is the result of a
traceroute to the ubuntu server from which the downloads are being
performed? Or, what are the results of running MTR against the host
for a minute or two? For example,
