My Mac mini late 2012 behaves strangely:

When awake the computer answers ping correctly:

64 bytes from icmp_seq=5 ttl=64 time=4.201 ms 
64 bytes from icmp_seq=6 ttl=64 time=4.823 ms
64 bytes from icmp_seq=7 ttl=64 time=5.108 ms
64 bytes from icmp_seq=8 ttl=64 time=4.400 ms
64 bytes from icmp_seq=9 ttl=64 time=4.523 ms

Right after going to sleep it stops responding, while it switches to 100 MbE:

Request timeout for icmp_seq 10
Request timeout for icmp_seq 11
Request timeout for icmp_seq 12
Request timeout for icmp_seq 13

But then, still sleeping, it responds again. It's still on 100 MbE.

64 bytes from icmp_seq=14 ttl=32 time=3.897 ms
64 bytes from icmp_seq=15 ttl=32 time=3.918 ms
64 bytes from icmp_seq=16 ttl=32 time=3.906 ms
64 bytes from icmp_seq=17 ttl=32 time=4.090 ms
64 bytes from icmp_seq=18 ttl=32 time=4.066 ms

This also works via IPv6. Why is this?

  • Is it possibly related to WoL? – zwerdlds Mar 25 '13 at 14:59
  • Maybe, but I don't see any reason why. – bot47 Mar 25 '13 at 15:04
  • The network card has to be awake to WoL so looks like it also responds to pings (or is this actual WoL) – mmmmmm Mar 25 '13 at 15:39
  • Have you ruled out bonjour sleep proxy and that your router / switch might be responding to network requests while the hardware is asleep so that it can send a wake message to the hardware should you need to use a sharing service remotely? – bmike Mar 25 '13 at 15:43
  • Can be a sleep proxy or router as I detached all other devices for testing purpose. As soon as I disanle WoL, the Mac shuts down its ethernet port making itself unreachable. – bot47 Mar 26 '13 at 14:26
