I could not do it wirelessly, but if you have a 622 or a 722 (maybe others) and have an extra wired port on your wireless router then get a Homeplug for about $20. Plug it into the wall (will not work with most surge protectors), plug an ethernet cable into it from your router and then plug your dish receiver into the wall and you should be all set. I have two receivers set up this way (1 Homeplug) and it works great.
