My network card goes to sleep and requires a reboot

I recently upgrade my MAC-Pro to OSX 10.9.
When my computer goes to sleep it seems my network card goes to sleep as well.
The computer comes back, but I have to restart to get my network card to work again.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

After recent update to airport on iMac, the wifi connection is lost when it goes to sleep and requires turning off wifi and turning it on to reestablish contact.

After recent update to OS on iMac, communication to airport is lost when computer goes to sleep. To reestablish connection, I need to turn wifi off then on.

same problem here.
i have a time capsule.
symptoms:
excessively searching for network
but more often than not, it cant find the correct netowrk that is correctly stored in keychain
if i try network assistant opened through safari not finding its page, then it can find the right network after i enter in the password again. it connects. but only for a few seconds then it loses the connection again.
the only fool proof workaround for me is:
1/ shut down time capsule. restart time capsule.
2/ restart mac with airport turned off.
3/ after restart manually select the network from the wireless icon in the menu bar
airport utility is a complete waste of time
old airport utility is still better.

Is there a way to detect the event when device goes to sleep and the screen blackens?

I want to detect the event when the iOS device goes to sleep and the screen blackens?
Is there any way to do it?

Hi,
A small idea, please check whether it will work or not.
You can achieve this by using combination of DNS server and reverse proxy server.( Customized apache). Make 'A' record for www.abcd.com to reverse proxy server IP address in your DNS.
So it will resolve your reverse proxy IP address for requests.
Configure appche to accept incoming request for www.abcd.com and points towards www.abcd.com/parameters.
I think this will solve your problem. Only one condition is that proxy server will communicate with www.abcd.com on behalf of client.
Follow the link for configuration of reverse proxy server

3 year old iMac 24 running OS10.7.4. After it has been on for a day or so, it stops going to sleep and becomes very slow. This only happens when Safari is running. Quitting Safari solves the problem. Has anyone else have the same problem?

Hello Albert, see how many of these you can answer...
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
http://support.apple.com/kb/PH7029
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab, are there a lot of Pageouts?

Tom:
I performed the steps indicated but this morning when I clicked the mouse and hit the space key and clicked the track pad again as before nothing happens.
I hold the power button for a few seconds and the screen fills as if the computer was normally awakened but it is locked up.
Then I have to shut it down with the power button and then power it up as a reboot.
Not good...SMC reset didn't work....Throughout the day yesterday I put the computer to sleep and woke it up normally. It seems to be a overnight problem.
Am I going to have to shut it down everynight?

I have just got an iMac 21" and it continuously freezes when it goes to sleep and also when the internet is trying to load, i have tried three different browsers but it still does it (safari, google chrome and firefox), does anyone know what is wrong?

I have just got an iMac 21" and it continuously freezes when it goes to sleep and also when the internet is trying to load, i have tried three different browsers but it still does it (safari, google chrome and firefox), does anyone know what is wrong?

To fix the freezing when sleeping problem go to System Preferences>Energy Saver and set 'Computer Sleep' to 'Never'. It seems there is a problem for some with Bluetooth failing to wake after sleep. This fixes it 100% for me and many others on here, until Apple issue a software update to address it.
Not sure what to suggest on the internet problem. I assume you are connected and receive and send emails OK.
Edit: To try to troubleshoot the internet issue maybe try turning the Firewall off: System Preferences>Security & Privacy>Firewall tab.

My computer is going to sleep and wont wake up by touching keyboard or mouse. I have to use the power button

Can anybody help? My computer is going to sleep and I cant wake it(bit like a teenager) by using the mouse or keyboard. I have to use the power button. Any ideas?

Hmm, that support link doesn't like me.
Do you have the discs that came with the computer? If so, put Install Disc 1 into the combo drive and boot up while holding the C key. Does anything show up on the screen? Do you hear the fan running? When running from a CD or DVD, the fan usually runs at a fairly fast pace and should make some noise.
Keep in mind that you have a 1-year hardware warranty with any new or refurbished Mac, so if something has gone wrong, you should be able to have it replaced free of charge, unless the MacBook shows some form of damage.

My e9107c desktop goes to sleep and them in a few hours or minutes has an unexpected power failure.

My computer goes to sleep, will wake up and run fine. It never fails while using it for hours. Once I leave it, it will go to sleep. If I come back and it is asleep it will come back on and work fine. However if while its asleep it has an unexpected power failure I have to turn on the computer and it will restate and work fine. Its like it goes to sleep and forgets it needs power and shuts off but doesn't shut down the operating system and causes a kernal 41 error.
If it were a power supply failure or an over heating problem I would expect it to occure while using the system, not during sleep mode when everything powers down. It used to work fine but the last few months the problem showed up. If I shut down the computer and them come back and turn it on it works fine. So I just don't let it go to sleep and turn it on and off.
Any idea why it would loss power while sleeping?

I think I have resolved my problem by uninstalling my cell phone software : Sony Ericsson PC Companion 2.0 I found that this program was interfering with windows when I wanted to turn off my computer and stopped shut down. It interfered more after two recent upgrades. I don't think Sony Ericsson has very good programer, because the more they upgrade the program the more it conflicted with Windows 7 64 bit OS I had this program on my system for a long time before the problem arose. I uninstalled the program and noticed my system ran better. It shut down without forcing any program to end. Since there was such a dramatic change in how the system worked, I tried to reset my computer to go to sleep and not shut it down. It works a designed and no longer loses power while sleeping. I didn't think an installed program could affect this feature but apparently it can.

Try setting the Energy Saver to "never" and uncheck "put hard disks to sleep when possible". You can allow the screen to sleep after any suitable time.
Hope that helps. Regards.

MBP goes to sleep and only wakes up for a moment... then sleeps?

My MBP started doing this today. Open the display, it wakes up for 1 second, then it goes to sleep and the screen disappears...? I tried to reboot in safe mode but it does the same thing again. Cant get it to stay on for more than a moment... any tips?

What new features are you mentioning, specifically?
The bulk of advancements w/SL are under the hood it would seem.

Powercfg sets power plan with never sleep but system goes to sleep and locks the screen

I created a command (.bat) file that executes 'Powercfg -s 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c' where '8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c' is the class name for power option (HighPerf) that sets sleep to never. Then I created a scheduler's task to execute
this command file at specified time. The goal here is to switch at this time from power option that has sleep in 1 hour (Balanced) to the power option that never sleeps.
At the designated time the power option changes from Balanced to HighPerf but after some time computer both goes to sleep and locks the screen. I do not know whether this happens at the same time or not. It is just that when I get to my computer some time
(2 hours) later, it is in the sleep mode (the light on the power button is amber), I need to press the power button to wake it up and when it comes to life I find out that the screen is locked and I need to enter the password.When I open Control Panel it shows
that HighPerf power option is selected. Yet, the computer went to sleep and the screen got locked.
All this does not happen when I set HighPerf power option from the Control Panel.
I am using Dell XPS 8500 desktop with Windows 7 Home Premium, so battery and closed lid settings do not apply as they do not exist on this computer, so those settings are not at issue.
Thank you
Isa Ten

Hi Isa,
Based on your goal "The goal here is to switch at this time from power option that has sleep in 1 hour (Balanced) to the power option that never sleeps.", why didn't you set the Balanced option to never sleep?
If you just ant it at one time to switch, you need another task to change back. Otherwise, it keep "never sleep" and "high perf"status.
Meanwhille, check your hibernate status of these power plan under sleep tab:
Power Options->Change Plan Settings->Change Advanced settings, you see a tap "Sleep"
