In regards to hooking the 722 up to the internet, would it be possible to purchase a USB Wireless Network adapter for it to be connected? I don't have any hard wired connection in my living room so it would be this or I've heard of using a Linksys Wireless Game router.
At least for now the USB interface is only configured to work with storage devices. Have you considered HomePlug? It is built in to the 722 and you'd need an adapter for your switch/router. I've not used it, but many on this forum do and seem to like it.
Wireless bridge. Install dd-wrt firmware on a compatible router and you're good to go. I use an older version Linksys WRT-54G. Works great for connecting both the 722 and XBox360.
My 722 is connected to my network with a Cat5e cable. If I install a sling Catcher I'll use the cat 5 from my 722 on the sling catcher. The 722 will remain connected via phone line.
Is the dish online thing the only use for connecting to my network? Is there anything else I'll lose if my 722 isn't connected. will my 612 still be connected to my phone via DISHcomm?
