However the ability under windows to make BOTH of them the default

fine without any packet losses.
 

Oh. I wasn't meaning that that was the *exact* issue in this case. It was merely a nice swipe at Micro$oft.
Linux doesn't allow of more than one default route.
*However* routing with more than one interface active is complex, especially if they connect to the *same* network.
If you have two interfaces active on the same network, which one is going to be used to access that network?
I am not claiming this is the answer, just that it may be due some consideration.

This is while running Debian, not raspbian, but at least it shows that this
scenario can work on Linux - I am at a loss what happens on the problem
machine.  Probably some tcpdump/wireshark tracing, maybe even on both sides
of the access point, is required to get at the cause of the problem.
 

I think some careful thought and experimentation may get you there quicker.
