Good explanation on how Homeplug/Ethernet work via DishComm. I see how that could happen IF I ever had a 722K.
Thanks... I figured it was worth explaining even though you did rule it out, just in case it comes up again maybe you (or someone with a similar problem) will remember this thread.
I do have a wireless capable router and I used WPA2-PSK (AES) security along with MAC filtering. However, when I switched to wired connections, I disabled all wireless functions in the router.
I've spent way too much time on this and there doesn't seem to be a solution.
Yeah... I can't think of anything else... so unless someone is leaching your internet bandwidth in a noticeable way, I'm not sure what else you could do. I suppose you could explicitly ban the 722K MAC address within your router and that would stop it from showing up again. If you did that, and you don't get any complaints... then you can wash your hands of it.
