You have packet loss at your capture point from .17 to .9. Frame 258, .17 to .9 the sequence number is 38 and the next expected sequence number is 1398. Frame 261, .17 to .9 the sequence number is 13638, not 1398. There is a big gap of missing frames. Frames 262, 264, 266, 268, .9 to .17. The .9 device, is requesting a packet with the sequence number 1398. Frame 271, .17 to .9 the sequence number is 1398, and the next expected sequence number is 2758.
The first step is to fix the upload problem is to fix the missing packets' problem. The upload from .17 to .9 slows until the sender sequence numbers and receiver acknowledgement sequence numbers are aligned. My suggestion is to move your capture point closer to .17, to isolate if the problem is the transport or TCP device.
