I've had my 722 connected to the internet thru the built in HomePlug for over a year. I've downloaded a few things, but it seemed painfully slow. Now that I got in on the SlingAdapter deal, I've pulled the Ethernet cable from my BluRay and plugged it into my 722. From my router status page, it appears both ports are connected. Can I count on my 722 using the fastest possible method? Is there a way to disable the HomePlug? Is there a way to test the speed of either connection? Thanks.
