You get the network connection while the dishy is not connected to the <br>
satellites (there's even a status page and controls, stowing and unstowing for <br>

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