it's very clear that there is a computer in the dishy that you are talking to. 
You get the network connection while the dishy is not connected to the 
satellites (there's even a status page and controls, stowing and unstowing for 
example)

I think we've seen that the dishy is running linux (I know the routers run an 
old openwrt), but I don't remember the details of the dishy software.
