I am having the same problem. Did you find any solutions? I’ve been downloading an image to a host for 4 hours now and it is only 53% done. Normally this is a 50 minute job. I didn’t notice the percentage when it slowed down, but it was under 40%. I believe the network is not responsible as I’ve changed switches, cables, isolated the client and FOG on a known good switch, etc.
I have version .32 also.
