Yeah, ours originally could not send data back to the dashboard for a few reasons:
1.The dashboard doesn't update correctly the first time you run the dashboard update. You have to uninstall it and run it again. When it has worked, your dashboard should have a compass-looking thing in the lower right corner.

2.The crossover cable that our electricians put in was both rather frayed, and also wrapped around some high-current power lines. This was kind of a one-two punch in that the lines put out enormous amounts of noise, and the damage compromised any shielding that the cable might have had, it would drop something like 95% of the packets when it was near the lines.
