(Get the code!)
That is the first thing I checked days ago: Settings->Power Management is completely disabled on this system. By disabled, I mean I can do nothing, I get a message saying:
"Power Management configuration module could not be loaded. The Power Management Service appears not to be running. This can be solved by starting or scheduling it inside "Startup and Shutdown"".
Also, I commonly use suspend on my laptop, and it takes something like 8 to 10 seconds to wake up. Here I hear the disk for a second, and the network is up again (and this is an old hardware).
I did the test you suggested: issued while true; do date; ifconfig -a; sleep 60; done. I left it running all night long. Then I tried to ping the machine from another and I confirmed that it was unreachable as usual. So I checked the output of the command and I attached it. I see the system has not gone to sleep and the IP was never lost, but I see a large amount of dropped packets.
