Thanks, Wez, In fact both routes use WiFi for the last leg, but your point about MTU is an interesting one. How do I assess the "real and imaginary" MTUs?

The difference you've highlighted is that the "target" machine is on Wi-Fi, not cable, which can cause issues. You might also check, for instance, what the target computer thinks the MTU of the Wi-Fi network is, and compare that to what it really is - if it's smaller than the server thinks it is then the connection is likely to stall as soon as a significant amount of data gets transferred.
