GMTA! I tried that yesterday. I found a Gigabit Ethernet switch (Netgear GS605v4) on the shelf and cabled the X4000 directly to it, and the switch directly to the U-verse Residential Gateway.
I spent some time and narrowed it down somewhat:
1) The symptoms are replicable. Any time the X4000 Ethernet cable is removed, even if the last source selected did NOT need Internet access and the receiver is on red-light standby, its connection to the Internet will not be recovered when reconnected (but to the LAN will).
2) If instead the cable from the Internet to the switch is disconnected, the receiver WILL recover Internet access when powered on again.
Apparently the traffic between the switch and the other devices using it (Apple TV, Global Cache GC100) is enough to keep the connection alive if the Ethernet cable is not unplugged from the receiver.
What I cannot explain (but would love to learn) is why only the Internet connection fails to recover -- the LAN connection returns with no user intervention, as evidenced by our ability to continue to use iRule and IP commands to control the X4000.
NOW I have something replicable I can present to Denon.
