If a major kernel upgrade happened, the old one should still be there. You
could drop back to the last one with grub and see if that makes any odds.

And presumably the ubuntu machine is running 2.6.20-16-generic? You see
the issue on ubuntu but not on windows, right?

So what exactly have you varied?
- problem affects debian (testing), ubuntu but not windows?
- problem happens in both houses -- is that the same debian machine? Is it
the same ISP? Is the router the same on both places?
- happens with several download tools.
- you've used various sites, presumably very different locations?

It might be worth sending the relevant tcpdump output (or wireshark which I
presume is similar).
