10.7.3 issues with reconnecting to the Internet after waking from sleep mode?

My iMac worked great until this last update. Now it does not connect to the internet after I wake it from sleep mode. Any fixes?

I have a similar issue. My connection has been rock-solid since we went to Uverse, and now my computer loses the internet every 60-90 minutes or so. Driving me nuts. iPhone still on wireless router to internet, so problem seems to be computer.

My macbook pro (lion 10.7.2) takes several minutes to connect to the internet after waking from sleep. Is there any way to make this instant?

Hi
My Macbook Pro 15 inch takes several minutes to be able to connect to the internet after waking from sleep. Does anyone else have this problem and is there a fix?

The message that comes up when I click on "TomTom Home Install" is "You cannot open Home Install because Power PC applications are no longer supported." Does this mean that the TomTom, which is absolutely vital to my life - well, not literally but you know what I mean - can no longer be used with my MacBook Pro?
What that means is that is can't be used with Lion 10.7. PowerPC was the chip Apple used up until 2006 when they switched to Intel. At that point, they created the Rosetta emulator to allow for PPC support for 5 years. They finally dropped the support with the release of Lion. It will only work with OS X 10.6 or earlier. The other option is to purchase a new GPS, which can be had for $100 for a decent one.

My iPad loses it's ability to connect to the internet after awaking from sleep mode. Needs to be rebooted to reconnect.

My iPad loses it's ability to reconnect to the wifi after sleep mode often times, but not always. It is very annoying because it requires a reboot to reconnect. It is running the latest iOS software update. I have also reset network settings to the factory defaults. My wifi is working fine, and all other devices in my house have no issues at all.

Well, I think I have finally come up with a solution. It seems this issue happens when it auto locks. I turned auto lock to "never" in settings, and the issue has not happened since. Seems there may be a bug in this feature???
I now use manual lock, and upon awakening the wifi is now fully working.

Thunderbolt Display has issue with weird washed-out colors after waking from sleep (after upgrade to Mavericks)

I've got a Thunderbolt Display that I use with my Macbook Air (mid 2012) - usually in clamshell mode.
When I let the computer go to sleep, and then wake it up by clicking the mouse, the monitor turns back on but the colors are washed out and purple looking.
The display goes back to normal when I unplug and replug it to my laptop.
I first noticed this problem after upgrading to Mavericks.
I made a video demonstrating the issue here:
http://www.youtube.com/watch?v=19179-MVpWA&feature=youtu.be
Any ideas?
Thanks!
Will

Same thing for me too. Late 2012 13" MBP Retina. I have to unplug the Thunderbolt cable and plug it back in.
This has only started for me in the last two days. The first two weeks of Mavericks was ok.
Update: I just got back from a trip. I was using the laptop separate from the Thunderbolt display. I hadn't restarted since I returned and connected the monitor. I've just rebooted, and put the computer to sleep. After resuming from sleep, the display is ok. Maybe try rebooting? I'll update if it continues.

My MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode

Hello, everyone. Since I updated to Yosemite, my MacBook Pro won't reconnect to my Wi-FI automatically after waking from sleep mode.
Does anyone know how to fix that?
Thanks in advance,
Arthur.

Hi, arthurpacifico.
Thank you for visiting Apple Support Communities.
Here are a couple troubleshooting steps that I would recommend trying to see if it corrects this issue.
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
Reset your computer’s PRAM
http://support.apple.com/kb/HT1379
If the issue persists, try the troubleshooting steps I have attached below.
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
After waking from sleep or starting up, your computer may not show that it is connected to a Wi-Fi network.
After start or wake, your computer may indicate that it is connected to a network, but does not connect to the Internet.
Solution
Use these steps if your computer does not automatically connect to your desired Wi-Fi network.
Check your TCP/IP settings in the Network pane of the System Preferences. Click the "Renew DHCP lease" button
Choose System Preferences from the Apple menu.
Choose Network from the View menu.
Select Wi-Fi, then click the Advanced button in the lower-left hand corner of the screen.
Click the TCP/IP tab from the top of the screen.
Click the "Renew DHCP lease" button.
Select the Wi-Fi tab and view your Preferred Networks list.
Select each network and click the minus sign to remove those networks from your Preferred Networks list.
Click OK and close the Network preferences.
Remove your stored network passwords using the Keychain Access Utility.Restart your computer.
Open Keychain Access from /Applications/Utilities. Your window will look like this:
Remove your AirPort network passwords from the login keychain: Select the "login" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Remove your AirPort network passwords from the System keychain: Select the "System" keychain from the Keychain sidebar. Click the "Kind" column to order the list of keychain items by their type. Remove all entries of the kind: "AirPort network password".
Note: The above steps will remove your Wi-Fi network passwords. If you do not know them, or if your network does not use passwords to restrict access, you should contact your network administrator.
Join your Wi-Fi network. You will need to enter your password for your network again if it requires one.

Airport crashes with Leopard after waking from Sleep mode

So I've always had airport issues (1st gen intel) and I was hoping Leopard might help, but now my airport shuts down every time the computer sleeps and it cannot be turned on. I have to shut down the comupter and turn it back on (restart doesn't work).
Any ideas?

I spoke with Tech Support this morning. Apparently this is a known issue with Lion. I found it interesting that the rep insisted on saying that "it is the way Lion functions" instead of admitting that it is a GLITCH in the programming. He even said that it happens randomly and not on all computers and not all users experience this. That ought to tell you that it's a glitch. Anyway, there is a "workaround" which is what you do to put a bandage on a persistent wound that should really get surgically stitched:
You either have to log out every time you leave the laptop, or you have to change Energy saver preference to set the display to go to sleep AFTER the computer is set to log out (in Security preferences).
Here is the article that instructs us on applying the bandage::

Suffice it to say that Apple does not plan on stitching this one up any time soon..

Problem with iCal events after waking from sleep mode

I have a daily iCal reminder that starts playing a playlist in iTunes at 6:00 am. However, if I leave the computer in sleep mode at night, and then manually wake the computer (BEFORE 6:00 am), the iCal event won't play on time...it's delayed 20-30 minutes. Any ideas why?

Have you tried it with a different mouse? I'm no expert, but you might want to find out, if the problem is mouse-specific.

Network issues after returning from sleep mode

I'm noticing this issue on T440, Twists, T420s, whether it's Windows 8, Windows 8.1 or Windows 7. Sometime around the end of last year and the beginning of this year, my users suddenly started reporting problems with the machines after returning from sleep mode. The network adapter (whether plugged in or using wifi), would show limited connectivity and would not connect to the internet until the machine is rebooted.
I've tried updating drivers, using system restores, disabling the network adapters from shutting down to conserve power, OS network diagnosis & network adapter resets, none of which has worked. Hibernation is disabled on all machines.
The only fix I have is to reinstall the OS over the top of the system and reinstall all updates. Looking for help with this issue.
Thanks!
Solved!

Macbook Retina with Mountain Lion issues after waking from sleep.

Macbook Retina with Mountain Lion has the spinning beach ball of death after waking from sleep a few times. Anyone else seeing this? A fresh boot is very quick, but waking from sleep lags at times. Then after a few times the spinning beachball of death appears and nothing is responsive making me reboot the machine.

I've been suffering from this too, and am currently trying this:

Seems to be tied to this 'Power Nap' feature. I tuned it for 12 hours instead of 24.

Since updating to Lion the iMac won't recognise the external hard drive (maxtor) when waking from sleep mode,

Hi All, Since updating to Lion, my imac won't recognise the ext HDD (Maxtor) when waking from sleep mode, I have tried another port, diisc utility (Ext HDD not listed in here) but nothing works. I now find that I have to restart the imac to get the drive recognised..which is fine until the imac goes into sleep mode then I lose the drive and have to restart etc etc.....anyone suffering same issue. The Ext Drive worked perfectly until the upgrade..

Thanks for this, and apologies for delay in replying...in between seeing your post I backed up the ext hdd to another mac and used the disc utility to erase and repair and then re mounted the ext hdd. OK. I have then tested the ext hdd being recognised when waking from sleep mode a few times and everything appears to be fine. If this doesn't work (long term) I will follow the instructions as you have suggested....
I now have a new problem with my HP printer (Photosmart Plus) which is not being recognised by a new wireless router..Ok whilst the router is switch on and I have reconfigured the printer..but when the router is switched off overnight and then switched back on...I get a 'printer is not connected' message and have to go through the re configure routine all over. I am minded to think this is a router problem as the same issue is happening to my wifes Mac Book Pro (which is only a few weeks old)...any suggestions..

Trackpad unresponsive after waking from sleep with new 17" MacBookPro

We have two 17" MacBookPros and both have this symptom. After waking from sleep or booting, the trackpad is unresponsive. Eventually full control comes back to the trackpad but it takes a while.
Both computers are up to date with all software.
Any thoughts?
Really irritating.

Perhaps they are freezing for awhile? Maybe basic repairs are in order.
Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them. Disk Utility's Disk Repair is not perfect and may not find or repair all directory issues. A stronger utility may be required to finish the job.
After that Repair Permissions.
No need to report Permissions errors....we all get them.

Short flickering when the notebook wakes up from sleep mode MacBook Pro Late 2013

Hello everyone!
I have a question concerning the display of my new MacBook Pro with retina display (late 2013).
Sometimes when opening the lid when the notebook wakes up from sleep mode, the display is flickering for like two seconds. Then everything is normal again.
This specially occurs when the lid has been closed for a longer time. It makes no difference if the power adapter is plugged in or not.
Have you experienced a similar flickering with your MacBook Pro?
Thank you in advance!

Hello!
I have the same problem with my late 2012 MacBook Pro Retina. The constant flickering after being awoken from sleep was a minor annoyance for me so I contacted Apple Support.
I shall explain what I have done thus far, and I recommend you follow the same steps as I did to tick off possible causes:
Firstly, I reset my PRAM (http://support.apple.com/kb/ph14222) and SMC (ttp://support.apple.com/kb/ht3964).
The issue still remained so I checked if the flickering occurred in a new user (if it does not then it points to your account having a setting which is causing the flickering - possibly third party). For me the flickering continued so I tested it in Safe Boot (which worked fine!).
I then ran (just to be certain) the Apple Hardware Test (http://support.apple.com/kb/ht1509). All seemed to be OK. So I reinstalled OS X and still the issue remained.
It was then I had an Apple Support person 'screen share' with me and we went through certain folders. My GPU folder had an unusual amount of files so we trashed them and began a restart however this led to a bigger problem; my notebook wouldn't boot (not even in Safe Boot!), so be very weary at this stage, I'm not sure if this was a rare case or we deleted something we shouldn't have. I then had to go into recovery mode to get back to square one.
Back to the initial problem I reinstalled a 'clean' OS X version from recovery mode; this was to determine whether if the data is corrupted on my account or if it's something else; most likely hardware by now even if there was nothing that came up in the hardware test (it won't account for everything). I checked from both a backup of my data and then from a fresh user after reinstalling OS X and still the flickering continued.
It was then a Senior Apple Support person set up an appointment to have my MacBook looked at and possibly repaired (it could be a minor wire causing the problem).
That is the point I am at now, so for my case it seems like a minor hardware problem. If your case is as similar as mine I recommend making an appointment with them to run more sophisticated hardware tests that your own MacBook would not run.
I will comment again when my issue is completely resolved for those who come across this Discussion in the future.
Hope this helps!

After waking from sleep, my iMac (Lion) is unresponsive. The mouse moves, but when I click things it won't open them.

After waking from sleep, my iMac (Lion) is unresponsive. The mouse moves, but when I click things it won't open them.
This has happened EVERY time the iMac goes to sleep for the last few days.. the only way I have found to resolve the issue is to manually restart the computer each time via the button on the back of the iMac.
Any and all help is appreciated!
Thanks

FWIW, I never sleep my machines or their HDs, just their displays and never have an issue waking up the displays, usually run 24/7. Give that a shot.

On my new iMac, mail has no sound after waking from sleep. If I select do not wake for network access in general preferences, the problem does not occur. Anyone have an idea on how to fix this?

Same here on an older iMac since Lion. Thanks for the uncheck wake for network access tip though, it doesn't do it either in that case, I will leave it that way.

Network mounts don't reconnect after waking from sleep

Hi,
I'm a network administrator for a small TV studio that's Mac-based. We had an up-to-date upgrade from Lion to Mountain Lion on one of our iMacs, plus updated a couple of our others for testing purposes. They're connected to a Lion server with Open Directory, and network shares are set up such that when a user logs in, the shares are mounted and available on their desktop.
Unfortunately, on the Mountain Lion machines, when the computers are woken from sleep, the shares are no longer mounted. I thought that maybe this might be resolved in 10.8.1, but it's still not fixed in 10.8.3. It's especially a problem when a document is open on one of those shares, and then the app fails because the file is no longer available. Note that this does not happen on the Lion machines.
Has anyone else come across this problem? Is there any way to fix it, or is it an OS bug? I'm not willing to roll this out to the rest of the network until I can get this sorted out.
James.
EDIT: I've just found other discussions with a similar question to this (a search before posting didn't show anything until I posted this one!). That said, there's still no answer to the problem. Can we get Apple's attention with this one??

Prevent them from sleeping? Apple is moving towards a more mobile world where wireless resources come and go. If you are still working with wired connections, you might need to make some changes. Not sleeping is once answer. AFP has some issues with passwords that cause problems with automount. I think they are fixable and I've always had a plan to write a little Keychain-aware command-line mounter for autofs. Always too busy though. I know that AFP supports Kerberos with automount. Since you have all Mac equipment, it seems like you could implement that pretty easily, well, as easily as Kerberos. I've never used it but I've heard stories. If you ware workng with an old-school topology, you could go to an old-school network like NFS. There are any number of hack-arounds. There are tools that will automatically run scripts (or mount drives) upon wake. You could replace those mounts with aliases (not symbolic links, true Mac aliases) that will get automatically mounted when you double-click on them.
