thanks for the confirmation trap_jaw.

I tried to repeat the problem, but I'm still confused.

I thought maybe because one of the kids had been running Acquisition on another machine earlier, but since the firewalls are off and the router maps and forwards a different port to each machine, I didn't think that was a factor.

After 4 trials, all I can say is that it's not a 3.8.1 problem, and that I don't understand the effect of checking the option to Force IP.

Any suggestions for how to understand these numbers, esp. the drop in uploads?
