I have posed the question many times whether it is a switch or a hub, since nobody who seem to know there is a difference between the two seem to be in the loop, I keep reading hub some places and switch in others (even think the manual uses both descriptions but I could be wrong about that)
I do suspect it might be a hub, but I guess I can't get a proper answer until I hook four computers into it and run bandwidth tests which I am honestly not going to.
I honestly don't see why they would use a hub this day and age, it's not like a 4 port 100Mb\s switches are expensive.
So only reason I could see is if Denon dug up a time capsule from the 90's with a few million 4 port hubs in it they figured they might as well use them, I honestly can't think of any sane reason.
Doesn't seem like switches are becoming the norm in receivers either so if you are using the ports on this unit, chances are when you upgrade you will need to get a dedicated switch any ways, a $20 one will do just fine if not better.
And as noted sometimes networking as been a little hinky, and the main fix for that is disabling precisely the "always on" feature.
This is not a Denon only issue, in fact I got the same experience with my oppo 103d.
