That's certainly very strange.  I still think it's more likely to be a
software problem than a hardware problem.  The only relevant difference I
can think of between GPA and a switch like this is that at GPA, there's a
DHCP server handing out addresses.  On a simple switch with no internet
connection, the computers have to adopt link-local IP addresses (169.*).

One possibility is that, in the absence of a DHCP server, the computers
are not correctly acquiring link-local addresses.  Bill can confirm this
on Monday, I guess, by looking at the IP addresses shown in ifconfig in
the no-internet configuration.

Agreed.  These are different issues.
