Computer not waking over wifi

After updating to Mountain Lion, my iMac will not wake over wifi for admin access. I have tried to access the iMac through my MacBook, my iPad, and an iPod touch, but none of these devices with their various apps (file sharing, splashtop, file browser, good reader) can wake my iMac when it's sleeping.
Wake over wifi is supported on my Mac.
I have wake for admin access checked in system preferences.
I am uncertain how to proceed. Any ideas?

Still have the "can't wake up (or sleep)" problem after changing the Energy Saver option. I closed my laptop's lid. About 3 hours later I verified that the laptop was indeed "snoring" (front light) so I assume it was sleeping. I opened the lid and again the LCD panel remained off. Of interest, an external 20" display did turn on and did display content. I don't know much about the internals but it appeared that the video driver was still active and it's video memory had good contents. Otherwise, the laptop was completely frozen. I did try disconnecting and reconnecting the external display, hoping that it might trigger some interrupt handler--no luck.
I've now changed my MBP's video selection to "Better Power". I also tried closing and reopening the lid, leaving it closed for just long enough for the laptop to start snoring. It came out of sleep without problem.
FYI, for the three-hour test I did not add or remove any peripherals, including power; so no config change.

Messages+ not working over WiFi

One of the main reasons I switched back to Verizon and off of the iPhone is because my dad told me that if I use the Verizon Messages app (also known as Messages+) I can text him over WiFi. This was really attractive to me because I live in an area where I generally have NO service. (occasionally one bar now that I switched to Verizon. Thank the lord). This is not the case. My messages do not send over WiFi. If I don't have one bar of service, nothing gets in or out. Why? Why? Why? The information about Messages+ says it operates using WiFi. Is there any extra step I need to do? I am so frustrated that I can no longer text my husband throughout the day. I'm forced to use Facebook Messenger which is incredibly annoying. At least when I had my iPhone (which I hated) I could use iMessages to text iPhone users.

IHateMyTreo I certainly want to check into this for you. What kind of device are you using? Are you getting an error message when you try to send a text out? Message has a lot of nice options. You are also able to read and reply to texts over wifi on your computer or tablet too! Just log into your My Verizon and click on Messages. You will be able to read and reply to your texts from there as well as on your phone. I have Message myself and texting over wifi should not be a problem though Picture and MMS messages may need to be able to send over our network instead.

Hi Terri571,
Welcome to Apple Support Communities.
See these steps for setting up Wi-Fi syncing between your iPhone and new computer:
iOS: Syncing with iTunes
http://support.apple.com/kb/ht1386
Wi-Fi syncing
Open iTunes
To set up Wi-Fi syncing, connect your iOS device to your computer with the included USB cable. Select your device under Devices on the left-hand side.
In the Summary tab, select "Sync with this [device] over Wi-Fi".
Whenever the computer and the iOS device are on the same network, the iOS device will appear in iTunes, and you can sync it. The iOS device will sync automatically when all of the following are true:
The iOS device is plugged in to power
iTunes is open on the computer
The iOS device and the computer are on the same Wi-Fi network
While the iOS device appears in the left-hand column of iTunes, you can select the content tabs and configure sync options.
Click Apply or Sync to sync the iOS device.
If the iOS device does not appear in the Devices section or you are unable to sync, please see this article for troubleshooting.
Best,
Jeremy

IMessage is not working over wifi. I need HELP D:

My iMessage is not working over wifi. But it's only at my house. Actually it worked a while ago but then it stopped working.
The browser, email, app store, youtube and any other apps are working just fine over the wifi. It's only my iMessage. It won't send any message. It say message not delivered. Does anybody what is going on and what can I do to fix it? Thanks, before. (:

I recently moved my library on my time capsule
You mean you moved your music files to the external. The library is more than the music files.
Just copy the \Music\iTunes\ folder from internal to the Time Capsule.
Add the Time Capsule to your Login items in System prefs -> Accounts.
Hold Option and launch iTunes and select *Choose library*.
Select the iTunes library file int ehiTunes folder on the Time Capsule.
It is hte samae library you have previously. All artwork playlists, ratings, songs, movies, etc. will be there.
Genius is already there so nothing needs to be done.

Ipod touch is not syncing over wifi at home

Hi is there anyone out there that is having trouble with syncing there ipod touch with there home computer and receiving there email as well.
But are able to go on the wifi outside of thier home in public domains and only able to partially receive there email accounts.I am having an awful hard time with this especially after I took the last update had nothing but problems with this since. Always gives me an invalid arguement and the connection failed.

Hi, I read in another thread that you should try deleting all of your email account details in the prefs and start again.
I"ve got a few mail issues too with my Touch, but I"m not sure that it IS possible to sync over WiFi. I can surf & receive email, but I can no longer send it. I"ve only been able to Sync my iPod when hard wired . . . . .
As WiFi I can a link through any networks I have access to now, just can"t send anything. Think it might be ISP/OSX issues. G5 has suffered before . . .
hope this works anyway.

IPhone will not sync over wifi, iPod & iPad will

I just got the iPhone 5s, and I can't seem to sync over wifi. I can sync with my iPad and iPod over wifi, so I think my network isn't the problem. Everytime I plug my iPhone in to my MacBook, the sync over wifi option box is not ticked, I tick it and sync, but the computer never seems to see the iphone, and when I plug the iPhone in the next time, the option box for wifi sync is un-ticked.
I'm running a late 2008 MacBook (the last of the old black ones), with OSX 10.7.5, and iTunes 11.1.4. All of my i-devices are running iOS 7.0.4.
Any help with this would be very much appreciated, this issue has really been irking me.

Why does Time Machine not work over wifi but only via ethernet cable ?

Hi everyone,
It's been some time I have this problem now.
The first time I backed up my mac within Time Capsule with time machine, I chose to use the ethernet cable because the gigabit connection is much faster than the wifi for the first back up, but now, any time I want to update this back up, I need to connect the cable, cause "Time Machine can not connect to the Drive I picked" over wifi.
This is so annoying. Does anyone have a similar issue ?
Any solution ?
When I got this "error" I can use Utility Airport and get full access to the drive, even in finder. The only thing that doesn't work is TimeMachine connecting to the drive, even if it is detected by TimeMachine itself.
Thanks.
Riccardo

Typical Yosemite.
I suggest a full reconfigure of the TC.
Follow this list..
No files are deleted on the TC doing this although you might have to repoint your laptop to the backup.
Note.. even if TM does connect it will say it is going to do a new backup.. it is only when it starts that it discovers the backup exists and increments it.
Start from a factory reset. No files are lost on the hard disk doing this.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 for basestation and and TCwifi wireless name.
If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.
2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.
Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the computer itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.
Macbook can't find Time Capsule anymore
Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.
Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.

IOS 5.0.1 will not sync over WiFi with iTunes....

Is there anyone else with this same issue? I've only found one other thread on this in Support so far. If that's the case then I'm thinking maybe I have a system issue rather than iTunes or iOS.
Basically all my devices (4 total, 2 iPhone 4's, 1 iPad 2nd Gen and one iPad 1st Gen) show up on iTunes in the left side and I can click on them where general info will show up but that is all I can do. If I try and see music, apps, etc. it drops each device out and disappears. They will then reconnect and come back up on iTunes but I still cannot do anything further.
I can also try the sync button on each iOS device but then again the device will drop off of iTunes and I will not be able to sync.
Let me know if anyone else is having any issues with this.
Thanks,
Lew

I am having the same issue with my 1st gen iPad (3G/64GB).
After updating to iOS 5.0.1 over the weekend, I cannot sync to iTunes (10.5) under OS X 10.6.8. It does not seem to matter whether or not I have WiFi sync enabled.
I plug in my iPad to the USB cable, In the iTunes status window, I see a very brief message stating "Syncing with Grace." Then a very brief message stating "Cancelling Sync" or "Finishing Sync". Then I see a message stating "Waiting for sync to start".
The sync then times out after two minutes with a message "The iPad 'Grace' could not be synced, because the sync session failed to start."

App Store not loading over wifi on iOS 6

Since I've updated to iOS 6, I haven't been able to load pretty much anything in the App Store while connected to wifi. It all works perfectly fine over 3G... But I have 130 updates waiting and I'm not using my 3G data for that. I've also been having trouble loading notifications, photos and messages in the Facebook app but the news feed works fine (this is also over wifi only). Safari seems to be working fine most of the time. Any ideas?

I have a very similar problemon my iPhome 4S: Updating apps switched over to use 3G (after I left my house for example) or starts in 3G even that wifi is available. This consumed my free 3G budget completely and costs already more than 15€ on extra charges. This never happened in iOS 5. I think I need to either avoid updating my apps or switch off mobile data completely. The best alternative would be, to disable app updates over 3G. But this is not possible.

Bbm not working over wifi out of country. Same with email.

I am in the us and have turned off my data and mobile network and enabled wifi only. I was able to use bbm and email no problem over wifi but all of a sudden even though I'm fully connected to wifi with good signal, my bbm is not working at all and I'm. Not receiving emails. Please help!

The BlackBerry servers in Europe have been experiencing some problems over the last couple of days. That's why you've been unable to connect to any of the BlackBerry services.
Glad I could clear things up for you.

mfe - 2.09.208

I already have the default destination to internet.But it still doesnt give me the pop-up which asks me to choose the internet connection.
But under Settings>>Connectivity>>Destinations>>Internet, I have 2 access points.
Pri#1 - Vodafone Mobile connect
Pri#2 - my wi-fi access point.
Does this make any diff? Should I try flipping the priorities?
cheers!

Verizon Messenger will not send over wifi

I am using Verizon Message + on my S5 and for some reason it won't send text's over wifi. The service in my house is poor so text over wifi is important to me. I had a Droid Maxx prior to the S5 and it had no issues. Is this something with the S5 or is there a setting I am missing? This does work properly on my Samsung Tablet.

Hmm, that's strange eljeffe17! You should be able to send texts over WiFi with Verizon messages. Has this ever worked correctly for you on the S5? When did you upgrade your device? What is the exact error message you are getting?
Thank you,
