To be fair, both systems could have something wrong with them.   Given
that the more straightforward causes are being eliminated more
atypical reason have to be
considered.   Trying a recent Linux LiveCD of some sort to check on
this possibility is one option.

Some more ideas:

1. Maybe pings work because they are small packets.   Maybe something
is flaky in handling full size packets.  Try specifying packet sizes
to ping (ping -s).
2. Check stats on your network card with "ifconfig" to look for
errored or dropped packets.  If your home router has a status page
with similar info check that as well.

Good Luck,
