When they first came out with Dish Online we hooked up an ethernet cable and checked it out on our 722. Worked fine. Finally got around to running a cable to our 722 and 622. Both hang when we try Dish Online. Yup - we have L448.
Just picked up the same one - works great so far. One question - it seems to always be on even when the receiver is off - do you leave the external drive on or power it off when not in use?
