No Wake-on-LAN possible since updating to ML

I take it back. All I had to do is wait lon genough for the harddrives to go to sleep and Wake on Lan DOES NOT work. This is pathetic. I have had this issue since 10.7.2 I guess Apple just could not care less about things just working.

Have you also made tweaks suggested in this thread? If so they may have conflicted with what the update did. I installed fresh.

Tweaks? No. The only thing that applies to my case is that my time capsule is in bridge mode. There is no way I can avoid that. I have verizon FIOS and they have their router infront for all the TV services.

As the "About the OS X Mountain Lion v10.8.3 Update" article does not suggest any fixes related to the WOL issue I didn't expect too much after "upgrading" - ATV still can't wake my Mac Pro...

Can't your ISP put your router into bridge mode? Pretty sure that DHCP from your Time Capsule is a pre-requisite to wake your Mac and, therefore, kind of a tough one to blame Apple for. I feel your pain though. I was an early adopter of 100mb connection where I live and it took my ISP ages to figure out how to get their stupid router into bridge mode.

Cody,

I hate to bother you. Just wanted to ask you about your setup. You mentioned in one of your precious posts that you are in bridge mode behind a fios router. Is it actiontec router? Also do you have an ethernet connection to your computer, wifi or both turned on. In my case once the computer sleeps I can't screen share, file share, wifi sync, access music/movies from Apple TV. Any thoughts?

My set up is a gigabit managed switch behind the router. So I don't think any of these signals are going to the router. It is an Actiontec, one of the newer ones... v6 I believe. I only have ethernet to my Mac Pro as it doesn't have Wifi. The computer I usually hit it from is my MBP on wifi or ethernet, depending if it's connected to my thunderbolt display.

So had some time to mess with this today. Looks like I had networkPriority was set to 1, this means my Mac Pro wasn't actually going to sleep. So this isn't fixed.

However, what I did narrow down is the packet isn't actually being sent. It isn't that my Mac Pro isn't responding.

I downloaded Depicus Wake on Lan from DepicusWakeOnLan.dmg

It wakes my computer after I put it to sleep. Remote Desktop, ssh, nor file sharing wakes it, but that app does. That tells me the other servers aren't sending the correct packet.

I also strongly feel this has a lot to do with WakeOnDemand. But not sure what.

Similar problem, one day can use iPad music app to wake my Mac for home share, sometimes videos app. Then they don't work. Sometimes can use splashtop to wake it, then that quits waking it. Then I tried Fing app and it woke my Mac, then it didn't. Just now I couldn't get any of them to work so I tried the remote app and it worked! I wonder what i will have to use next time, if anything works.

JUNK, MADE IN CHINA, OVERPRICED, LIKE THE TOXIC PAINT ON THE TOYS THEY SELL. GOTTA HAVE IT BUT IT MAKES YOU SICK TO OWN ONE.

I would suggest that everbody post another support ticket here: http://www.apple.com/feedback/

The WOL prob is not depending on router configurations or any other hardware in LAN or WAN it is a bug in Mountain Lion, posted here since ML came out!

Give them a flood of bug reports, that won't wake up Your Macs but it might wake up the OS developement team!

@MackDougS

The software is written in the US. It's a software problem, not a hardware problem.

I sent feedback, I've reported a bug.

I'm quite confident the correct packet isn't being sent by the built-in apps. For now, I'll use the Wake on Lan packet sender to manually wake it up. Just a shame we have to wake them up with another app.

Well, I haven't tested it yet, but, there seem to be some free software solutions. Gotta love the hack:

Thank you for the link - which software did you download?

I hadn't decided yet & was hoping to do some more research or hear some feedback from the discussion board.

Has anyone tried any of these? How about some feedback on preferences? - Thanks on behalf of the group.

I just did some testing after I had the same issue. It used to work for me for weeks and then the Mac won't wake up on Plex or Back To My Mac requests. I tried every solution I could find on the web but this time without any luck (last time weirdly enough an SMC firmware update fixed the problem but it could be a coincidence). I had it set to have a static IP and I tested by changing it to a DHCP allocated address and that seemed to have fixed the problem. Tested by setting it to the original static IP and it didn't work. Changed it back to DHCP and got the same leased IP again and it didn't work. Chagned to a new static IP and it didn't work. I do have an APExtreme (recently updated to 7.6.3 - problem MAY have started then but again, could be a coincidence) but it's in bridge mode and the DHCP lease is from another router connected to it. I then changed the network configuration and turned off the DHCP on the first router and turned it on in the APExtreme without NAT (NAT is still turned on on the first router but that's irrelevant here). I had some entries in there for reserved IP addresses including the Mac in question and stayed with it. Tested it and it worked. Tested again and worked a second time too. There are two other Macs in the house that are also running 10.8 and they never had this WOL issue but then they've always been on a DHCP lease.

Guys, try 'renew DHCP lease' and see if it helps (make sure you get a new IP, not the one it already has - may have to restart the router for this). Somehow the IPs may have become 'stale' within BonJour, don't know. I'll update if this set up has any more issues.

I tried all of this using an ActionTec router. Even tried enabling an internet wake-on-lan port forward to x.x.x.254. Tried manual DHCP, static ip, renewing lease. No such luck. Can't say I'd be thrilled if the only solution was to purchase an Airport Extreme.
