Where is lwIP in all this?  If one end is windows, and the other end has
behaviour you like, which bit is the problem?

Can you point at packets in the capture you sent that that illustrate
this?

Your problem is not just a simple change in configuration, from what I
saw in that packet capture, as explained in the earlier message, there
appears to be something wrong with timing.

The packet capture provided does not show congestion as being a limiting
factor.
