Cant connect to internet after computer goes to sleep mode.

Everytime my computer goes into sleep mode it wont let me connect back to safari. It shows im connected but wont connect. Can anyone help me?

Hi there. I have the same sort of problem with my MacBook. To get the internet working again I have to restart the system. Sometimes the same sort of thing (shows I'm connected but doesn't really connect) happens when I'm in the middle of using the internet. I've posted a topic ("Problem with AirPort?") about this also and I've gotten a few responses already. Maybe one of them can help you out (no luck for me so far though).

Describe the issue in more detail.. as it doesn't currently make sense.. the AE should always be connected to the internet. It should never disconnect.. but the computer can fail to connect to wireless after sleep.. that is common problem.
See Tesserax docos if you have wireless connect issues after sleep.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Internet goes stale after computer goes to sleep and then needs to be rebooted to function properly

I mac with retina 5k display
internet goes stale after computer goes to sleep and then needs to be rebooted to get it working again

Please read this whole message before doing anything.
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, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Fans go on at full speed 1 min. after computer goes to sleep

Problem: Fans go to full speed 1 min. after it goes to sleep-mode. The fans will stay on until it wakes up from sleep-mode.
Computer: Apple Power Mac G5 Dual 2.3, OS 10.4.9, 4.5 GB RAM. 2 HD, late 2005 version.
The problem happens every time I put it to sleep, even right after it has been turned on.
I have measured the CPU temp to be as low as 36-40C and it will still turn the fans on high speed when put to sleep.
I have reset the P-RAM and the SMU.
I have installed a fresh version of OS 10.4.9 on second drive, booted from it and it still turn the fans on 1 minute after it goes to sleep.
I have had all the RAM out beside the original RAM. I did an extended Apple Hardware test which passed.
...any ideas ?
-e
5 Macs in total Mac OS X (10.4.9)

After trying all that, it sounds like it's hardware-related--possible logic board--but try this yet.
Do an Open Firmware reset: Hold the CommandOption+OF keys during startup. At the '>' prompt type:
>reset-nvram
Return
>set-defaults
Return
>reset-all
Return
The reason the fans are taking off, is because the OS stops communicating with the logic board.

Apple tv loses home sharing when my computer goes into sleep mode

Just recently, my Apple TV says that home sharing is off when my computer goes into sleep mode. It never used to do that - any suggestions?

I have the same problem here. Always back-ed up with Time Machine (OSX 10.9 Mavericks) to Western Digital drives. MyBooks, MyPassport 1TB (USB 3.0), all works fine. Time Machine is actually doing back-ups overnight. Since I got this new 2TB MyPassport Ultra USB 3.0 it's working perfect during days, but every morning when I wake up the MacBook from sleep, I get this annoying error:
Time Machine couldn’t complete the backup to “MyPassportUltra”.
Unable to complete backup. An error occurred while creating the backup folder.
Latest successful backup: Today, 02:27 am
I'm also not able to write anything to that drive, or unmount it. It stil shows up in Finder, and I'm able to read all the data perfectly fine. When I do a Disk Utility Verify Disk directly after, I get this:
Checking volume
disk3s2: Scan for Volume Headers
Invalid Volume Header @ 0: I/O error
Invalid Volume Header @ 2000021315072: I/O error
disk3s2 is not a CoreStorage volume
Error: This disk needs to be repaired. Click Repair Disk.
I don't click Repair Disk, as this will probably screw up my partition. Instead, I have to unplug the USB cable (which is bad for the drive, there's no time to park the drive's heads) and plug it in again. After clicking Backup Now, Time Machine immediately starts backing up, and the drive works fine the rest of the day.
I contacted WD Support, and they are sending me a booster USB cable. As System Information reports, the drive receives enough power though:
Current Available (mA): 900
Current Required (mA): 224
Unfortunately there's no firmware update for this drive, which will probably fix this. See this topic: https://discussions.apple.com/thread/4196704.

IPod Classic auto ejects from iTunes after computer goes to sleep on Mountain Lion

I posted the following a few days ago in the Mountain Lion as I am suspecting the OS has something to do with it, but got no replies so I thought it might be good to post this here too in case this issue would be familiar to some of you.
I usually have both a 160gb iPod Classic (original) and a 16gb original iPod Touch plugged into my computer and connected to iTunes, so I can listen to tracks from the devices straight through iTunes. This has worked very well for years, but since upgrading to Mountain Lion, every time the computer wakes up after going to sleep when I haven't used it for a little while, iTunes ejects my iPod Classic, and I have to replug it, but it doesn't do it with the iPod Touch. This never used to happen before, and is a tad annoying when it happens recurringly through the day.
I have also noticed that, if the iPod is ejected, it seems to erase the play count for the tracks I was playing prior to the computer going to sleep. This is no major issue, but it seems a bit odd.
I initially thought that this was happening on my work iMac but not at home (both running the latest versions of Mountain Lion and iTunes), but it does in fact happen on both computers. This behaviour only started when I upgraded to ML, and although it could be a coincidence, I think it may have something to do with it.
I am using the latest version of iTunes.
Can anyone help with this please?
Thanks

Hi there,
Thank you for your reply, that's much appreciated. In a way it makes me feel slightly better to know that it's nothing to do with my iPod, although it is quite frustrating. Don't Apple QA their products before releasing them anymore? I've had quite a few issues with ML since installing it. I understand you get bugs with new products, but that would be one quite easy to identify I'd think. Oh well, I'll have to suffer this like everybody else until Apple get it sorted.
Once again, thank you.

Final Cut Not responding after computer is in Sleep Mode

I put my computer to sleep for a few hours when I go away on a shoot. When I come back and wake the computer, final cut gives me the spinning wheel of death and is not responding. What is even more annoying is when I go to force quit the program, it doesn't quit from the task bar and the dot under the icon of final cut is still lit. Even after trying 10 force quits it still stays active. I am forced to shutdown my computer everytime and this problem happens everytime the computer goes to sleep and is woken up.
Is there a fix to this?

Which version of FCP?
Are you on a network?
How many drives are in your Mac?
And, if there is more than one drive, are you absolutely certain you placed your registration information on the correct drive?
The usual explanation is that FCP is trying to locate or verify the serial number (different behaviors in different versions). The drive where that info is stored is inaccessible (because the drive is not spinning and so is the same as not mounted) to FCP (which is loaded into RAM) and totally active.

IPhone 3gs cant connect to internet after OS4

Ever since i updated to OS4, i cant connect to the internet except at wi-fi hotspots. i reset all settings, restored the iphone, tried airplane mode on and off and nothing has worked. any suggestions?

I had the same problem that AT&T couldn't solve after my iOS4 Upgrade on my 3gs.
An Apple Tech double checked that airplane mode was off and then went to settings, restore network settings thru the phone's menu. It reset and suddenly all my 3g cellular connection was restored and everything worked again. But V E R Y S L O W L Y!
I am still getting 4-5 bars of connectivity, my all my speed tests show my 3g data connect at about 60-120 kbps or even slower. I don't know of it's an iOS4 bug or AT&T just overwhelmed by al the new Iphones added to it's network. I'm paying for "Unlimited Data" that now comes in so slowly, some of my apps "freeze" and time out when they can't connect.
And I have no official way of downgrading to 3.1.3 without hacking my phone...which can't be discussed here and may not even really work!

Losing connection to wireless internet when computer goes to sleep

I have a Macbook, with OS 10.5.6. I connect to internet via airport connected to internet via belkin router. When I close my macbook to put it to sleep i keep losing the connection to the internet. The airport is connected, its only the internet connection that is lost.the only way round this is to restart the airport or belkin router, when the connection is restored. does anyone know a solution to this problem?

Similar symptoms here. Fortunately my MBP "recovers". When I made some experiments with VPNs yesterday, I noticed, when switching the network environment, that the computer is requesting a new IP address. Maybe this will also happen when the Mac wakes up? And maybe the router doesn't respond properly? I would try to set a fixed IP and see what happens then.

Firefox stops working after computer goes to sleep 37.0.1

Running Win7 Home Premium and Firefox 37.0.1. Since this upgrade, when any of my three computers goes to sleep, Firefox stops working. Sometimes the process can be exited, but regardless, Firefox cannot be reloaded and the computer must be rebooted. When the computer has gone to sleep, and Firefox has stopped working, other browsers, such as Explorer also say they cannot connect to the internet. The fact that this problem simultaneously appeared on different computers following this upgrade suggests that this is a Firefox problem. The only way I can avoid this is to exit Firefox after every use. In many cases, the only web page visited during a session is google.

This is a known issue, and the programers are looking at it.

HP w1907 Monitor - will not come back after computer goes to sleep

When restoring my computer from sleep mode, the monitor flashes on briefly and then goes off. It takes multiple times of cycling the power on the monitor before it styays on. It is currently connected by an analog cable.

Have you tested what happens if you disable power save mode at monitor?

Cannot Connect to AE After Coming out of Sleep Mode

This happens on both my iMac and Powerbook. I don't normally use wireless on the iMac but I discovered that both computers are having the same issue when troubleshooting. When coming out of Sleep mode, the Airport device cannot connect to the Airport Express. The only thing that can consistently connect is my Blackberry.
I know it's not a reception problem as when I am able to connect, the signal is strong and speeds are very good.
Some things I have tried to fix the problem have worked but not consistently as the problem keeps happening:
-Turn Airport off and back on (On the computer)
-Unplug and plug back in the AE
-Turn off MAC Address Filtering
-Factory reset the Airport Express
-Select the Join Other Network option and re-enter my wpa2 credentials
-Uncheck Closed Network option
What could be the problem? I'm really thinking there is a software bug somewhere. I have also noticed if I make any changes in the Airport Utility the AE never recovers as it stays a solid amber. I have to power cycle the device.
It's using software version 6.3 and all my OS X updates are the latest. This is very frustrating. Any help appreciated.

I have tried both remedies mentioned above. I double-checked and my network is listed in the wireless advanced settings. It's the only network in my list. Airport is at the top in my Network Preferences as well.
I was hoping the update to 10.5.8 would help but the problem keeps occurring. One thing I have tried is leaving the "Closed Network Option" unchecked for my AE. Now, I am discovering when exiting sleep mode, I see my network but when it tries to connect, I receive the error "Connection Timeout". This happens on both computers.
The only thing that works the most consistently is unplugging the AE and plugging back in. Once I'm connected, it works great.
I tried using iStumbler to see if there were any other networks using the same channel but that looks okay.
I guess I can try using a different security setting other than WPA2, but then that is not really a solution. I'm about ready to just try some other newer wireless solution. It used to work flawlessly. I think until 10.5.4, I had no issues.

Computer Goes Into Sleep Mode By Itself

Experiencing a weird phenomenon this morning... my PowerBook is sending itself into sleep mode. The battery is charged and it's not overheated. It does it when plugged in and when unplugged.
When I hit the 'power' button to wake it up, it always comes back on, but then shuts off 10-30 seconds later. It's now been on without sleeping for ten minutes or so, but would still like to know what's causing this very un-Mac-like behavior and how to fix it.
Thanks,
Matthew
PowerBook G4 15" Mac OS X (10.3.9) 100G Hard Drive

Back to the beginning, then. Are you certain the Powerbook is actually sleeping? Is the sleep light pulsing? If not, the problem is that your backlight is going off, not that the PB is going to sleep. That would most likely indicate a bad inverter board. When the backlight goes off, shine a bright light on the screen, or shine a bright light through the Apple logo from the back side of the display. Can you see the screen image that way? If so, replacing your inverter will probably solve the problem — and if the inverter is failing, nothing else will.
EDIT: BTW, I meant to mention this earlier but forgot. In your original post you implied that you habitually hit the Power button to wake the computer from sleep. That's probably not a great idea, since there's a small risk that you'll accidentally shut it down that way if you aren't really paying attention. I always wake mine using a Shift key, which carries no risk at all of causing anything odd to happen — not even of typing a stray character into an open document, or moving the cursor from where I left it.
