That makes sense to me, but why is it only a very few web sites?  I
haven't heard complaints about poor wikipedia access, so it appears
that most other people don't have problems with that either.  One idea
I thought of is that maybe they have very tight timeout limits, and
since I am on dialup, I often exceed those limits and they then drop
packets.  I have heard about a couple things(ECN and SACK?) that can
cause problems with some sites, but I think I already have disabled
them in the sysctl.conf settings I included in my original message.

Any idea how I could trace something like dropped packets?  Looking
for the absence of something can be very difficult if I don't know
what I should be looking for.

Thanks for your suggestions.
