I had this working fine in June, but not so much today.
The setup is mostly like what is outlined here:

Things look fine on the RPi side (the date is wrong):

I can use wget on my desktop computer (win7-64) and see the connection and a
trickle of data:
$ wget 192.168.0.3:8081

Nothing shows up when I try to connect with Chrome.
I am thinking the issue is with the 2.9K/s data transfer rate.
