Stupid question...might your firewall be dropping packets? Check your
firewall logs.

Similarly, is there a difference in network connectivity between the
machine that works and the two that don't?

Also similarly, is the mfp on the wireless network along with the
functioning box, while the two nonfunctioning boxes are on the wired
side of your network? In that case, firewall and protection mechanisms
on the router might be interfering.
