Sorry if this has been asked before but can I use any wireless adapter with my 612 or does it have to be the $25 on from dishnetwork. If I can is there a trick to make it work? I have a wireless N one laying around and I'm sure it's plug n play. I just found out about the blockbuster movie thing. I know I'm behind the times but I have a receiver upstairs that I can't run Ethernet cable too. thanks kevin
