May 17, 2010 There are two implementations of 'Wake for network access'. The original implementation uses the standard Wake-on-LAN protocol where a special 'magic packet' is sent directly to the machine's ethernet port. The packet has to be specially crafted to include the machine's MAC address and when the port detects the packet it wakes the system. Using a handy network feature built into OS X and supported by most modern Macs, you can remotely wake a Mac from sleep using an iPhone (or iPod touch, iPad, and Android too). This is done using something called Wake On LAN (WOL), and it’s easy to set up in Mac OS X and use from a smartphone with the help of a free app. ![]() At I had written about a strange DNS issue with OS X and Firefox. That's gone away, but for some time now I've had a new problem: when I wake from sleep, it takes a long time before I can do any network access. Firefox and Safari just hang with spinning beach balls, ssh times out. Drivers for hp printer 6978.

I just can't start new sessions. Maddeningly, the problem would sometimes disappear entirely, only to reappear a day or so later. Download google earth pro for pc mac or linux. I thought that an Apple update or Firefox upgrade had fixed it. But no, it came back again. I thought it might be a DNS issue again, so I tried with hard IP addresses. No, those don't work either. I've found plenty of similar complaints on the Net, but for wireless activity. This is happening to me with a hard Ethernet cable on en0 - I have Airport shut off most of the time. Airport did give me a clue. I noticed that when I happened to be using Airport, whether here or elsewhere, I wouldn't get the sleep problem. As I said, I usually have Airport shut off. I don't know why - I just don't like anything running if I'm not using it. So I usually have it shut off. ![]() So what's happening here? Is OS X trying to use Airport for new connections even though I have it shut off? That might explain why existing connections are still fine. Here's another clue: If I turn Airport on and then shut it off, the hanging after sleep goes away for a while. That probably explains the supposedly random nature of this - I had probably turned on Airport for some reason. Maybe OS X just gets confused and thinks Airport is on unless it has been turned off recently? I don't know. The obvious fix is to just leave Airport on. I suppose that's what I'll do. Got something to add? Sun Nov 9 16:: 4750 badanov My guess would be if you disable ACPI most of your sleep problems will disappear. It has been my experience FreeBSD has an ongoing problem with ACPI Sun Nov 9 17:: 4751 TonyLawrence That's often been the suggestion for Wireless wake from sleep problems, yes. But given the symptoms, I think just leaving Airport enabled is a bit less drastic. I have no other APCI related issues, so why should I disable something that is useful? Mon Nov 10 07:: 4752 jtimberman I've been maddened by this just this evening, in fact. My Samba mounts from my Windows system caused all kinds of networking problems when I returned from sleep. The issue only happens when I shut the lid. System 'inactive' sleep hasn't been an issue. I too normally have ethernet connected and Airport off, since GigE is faster than 54G wifi:-). My main question, is Mac OS smart enough to actually honor the first device listed for even local network traffic (except specifically on the wifi)? I know it uses en0 for internet access. Mon Nov 10 10:: 4753 TonyLawrence I don't know. I'm still scratching around on this one.
