Hi,
I ordered the new NIC card direct from Denon Canada and got it in 2 days for $80 bucks shipped even though I was told $96. Also, I phoned Denon Parts when I noticed that I received the original part #CM860-3 instead of DM860 and asked that he send me that one instead. The rep said he'd talk to his senior tech and call me back in a few minutes and when he did I was told that the DM860 matches up with the 3310 and that I received an updated CM860 card for the 4310. Perhaps that's why there was a driver update notice in the above post? Don't know.
In any event, popped the card in, did a reset, shut it off and when I turned it back on again, hallelujah it was ready to do an update. Everything went smoothly but I admit I was still waiting for something to go wrong. Address was assigned, Internet radio & USB kicked back in as well as near instant switching between sources and soundfields. Hopefully this will be the end of this issue for good. I'll be the first on the horn if it isn't. Thank-you very kindly to all memebrs for pointing me in the right direction.
Threw a few pics up of the process below.
p.s. The NIC card is right on the very top layer of the receiver once you pull the housing off, can't miss it! I did have to snip off a cable tie though because it was pinning the card down. It's just like changing a stick of RAM, really easy to do.

Denon offered to pay shipping to them and shipping back to me but I did not care to send the unit for 2 or 3 weeks. Denon parts also said that they had a 30 day return on the part so if for some reason it did not work in my 4310 I had the option to return it. I am not thrilled about spending the $153 to get the unit working again but I was less thrilled with having to ship it off. The failure of this card was causing HDMI output problems, no USB etc. I was having to power the unit down to get the HDMI input/outputs to work so I decided to get it done now. The part arrived yesterday and it is currently doing a great job at playing "The Police" on Blu-Ray.
. So in the end I have chosen to spend an additional $75 and not have to be without my AVR. All in all not a pleasant customer service experience. This is my 3rd Denon AVR and I also have a Denon 602 video processor - I think they will be the last Denon products I own
