Thanks for the idea.
Some added info.
1) I can boot many OSs on the same hardware by using a disk caddy
for the boot drive.
2) Debian, Ubuntu, PCLinuxOS, Suse, ArchLinux (and others) work
just fine as far as downloading speed is concerned.
3) On an installed Fedora 9 on this machine, I tested with and
without IPV6, and even switched which NIC went to internet.
Results were the same: No Good.
4) Oh yes, I had a similar problem on a different PC as well.
Fedora produced the only distros that failed.
I can explore the suggestion re: bandwidth shaper, but am curious as to
why my network would be only sensitive to downloads that Fedora initiates.
Also, if some tweak to wget makes it work, what about yum and friends?
If you are on the right track, ie, the download is too fast, then I
offer the suggestion that Fedora doesn't allow enough buffer space for
the enet driver to handle the traffic. Buffer becomes full, transfer
stops, "peer" decides that there is some error, resets connection, and
we go to retry or next mirror.
I'll let you know what happens...
