Hi again,
Thanks for the clarification. When I first upgraded to 2.02, I discovered that several of the previous settings, although showing as enabled, needed to be re-saved and then rebooted to actually start functioning including the fan settings. The UPNP server is still a bit buggy also, so I would also recommend a "refresh all" and then a shutdown and restart. Things to check, hd temperature, smart test, try eliminating the hybernation settings, double check network "name" is the same on all computers and devices.
I am really mostly guessing, but it seems that the problem is either the 320 itself, or perhaps the network/ router settings. Let us know if you find anything. Good luck
