The Netgear N600 is simultaneous dual band (2.4GHz b/g/n and 5.0GHz a/n). I setup the home office (pc, laptop, printer) using the 2.4GHz feed and stream to the Blu Ray only using the 5.0GHz feed.

What's interesting is that in both rooms that I have tried out the BD85k, it always sees better reception on the 2.4GHz network (5 bars). The 5.0 only shows 3-4 bars for some reason. I always thought the higher the frequency the better the range.
