Wol mac os x mountain lion

Jul 31, 2: I sometimes have a problem with my Mini losing WiFi connection but haven't care enough to to investigate since I rarely need to connect remotely. DHCP might be the issue as you suggested so I'll look into that myself.

Might be worth trying a direct line into your router just to see if the pwer line connection is somehow contributing to the problem. You're absolutely right, one should rule out every possible cause for error. I will try a direct connection if the DHCP lease time does not solve the problem, but I doubt that the dLAN adapters have anything to do with the issue.

Network traffic is running perfectly well. Jul 31, 8: Ok, I did not expect that, but it really seems to be connected to the dLAN adapters.

They go to sleep as well, a few minutes after the mini did. That's why the connection breaks. I never had that behaviour with SL and Lion, but it seems to be the way it should have worked from the beginning. I tried a direct connection between mini and Time Capsule and it worked perfectly well, at least a few minutes after putting the mini to sleep. I did not try a longer period of time as I have no possibilty to connect the mini directly to the router.

My workaround will be disabling sleep mode until I find a solution. I'm on a Mac mini connected to an Airport Extreme and experiencing the same issue with wake for internet access not working. It worked perfectly before, and now it does not. Well, not what you were hoping but at least you narowed it down. I expect this is not the intended functionality and that it will be patched - hopefully soon.

Jul 31, 9: I am having this same problem. Once I upgrade I couldn't figure out why all my ports were giving me time out errors. I have services running on my mac that I access over the internet. After thinking about it, I narrowed it down to the sleep. Before ML my computer would wake up and I could connect fine. Now it is sleeping and will not wake up. I will have to change it to never also Aug 1, 2: Aug 1, 3: Aug 2, 1: I don't think that it will help much, but you can try.

As long as you're using a router that's offering the Bonjour Sleep Proxy service, using WiFi instead of wired connection may improve the situation. Communities Contact Support. Sign in.

This command can be sent via an online shell script to set the machine to wake every day at 3: You can also send a Wake-On-Lan packet to Apple hardware, although it only wakes machines that are asleep, not powered down. The advantage of the scheduled event is that it will power on systems or wake them hence the wakeorpoweron option.
