This is nonsense, BTW. I highly recommend connecting wired (vs. wireless), if you can easily do so.
This is funny. I just had an HR-44 installed Saturday. I had ethernet connected to my old receiver and told the guy to make sure to connect it to the HR-44. He gave me the same line that ethernet didn't work well with "whatever he said".
I connected my HR-44 to my 5GHz wireless network and it works great. I guess I could connect the ethernet cord up. It is still just sitting there. I kinda feel like it works fine as is and why mess with something that works.
