Factory reset shows no change at all.  Tried powering off/on while holding it in, holding it for 30+ seconds, no change.  PC does not get any connectivity when plugged in to the router, red X on the connection icon in the tray.  ipconfig reports "media disconnected".
I borrowed a replacement DGL-4300 from a friend and it is up and working fine so no issues with the cable.  In that process I did notice that his is a HS Rev. A4 and mine was the original A1, shipped with FW 1.0.  I guess mine is a lot older than I thought, maybe it was just too old of a version to use the 1.9?
I certainly think it is bricked dead.
Any other thoughts?  Is there any way to reset it from the WAN port?
