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
--2013-09-20 22:35:19--  http://192.168.0.3:8081/

    [                    <=>                ] 130,974     2.95K/s

Nothing shows up when I try to connect with Chrome.

I am thinking the issue is with the 2.9K/s data transfer rate.

Any suggestions?
