I recently got a Joey wi-fi access point and two wi-fi Joeys. I have my router/cable modem connected to a switch that feeds the Hopper 3, Xbox, receiver, etc. I had the Joey access point connected to the Hopper network port. Due to some other components being eliminated, I was able to move my Joey wi-fi access point closer to the router, so I tried connecting it to the router LAN port rather than the Hopper. It worked, and has worked flawlessly for over a week. This benefited me because of limited cable passages, so I thought I'd share it with others. No guarantees, just anecdotal evidence.
