Not re-connecting automatically after waking from sleep

Hello,
I have recently purchased the TC 1Tb version. I have set this up to be automatic for both channels and all seems OK. However, after I wake up the Imac from sleep mode, the wireless does not automatically re-connect. I have to manually re-connect from the airport symbol in the menu bar. I have an a normal AE before this, and I did not have this issue.

Hello Diane:
Welcome to Apple discussions.
Try clicking the mouse if it does not automatically pair.
I would also delete the preference file (com.apple.bluetooth.plist) and restart.

Mouse not connecting automatically after waking from sleep

Hi,
When I open my MacBook after it's been asleep, my apple bluetooth (non-mighty) mouse does not connect automatically. I have to repeat the setup new device wizard to get the mouse to work. This is 100% consistent and occurs every time.
This mouse was previously my son's and has a particular "affinity" for his computer. For example, before he deleted it from his own system preferences, the mouse would connect to his computer instead of my own even if he was rooms away from me. (this isn't strictly related, since it still occurs even if his powerbook isn't here or is sleeping).
Thanks,
Diane

After upgrading from Lion to Mountain Lion the wi-fi doesn't connect automatically after waking from sleep. I have a Macbook Pro. It's really annoying and I need help. Anyone?

Wi-fi worked fine before I upgraded and always connected automatically but now nothing seems to work. Does anyone know how to fix this?

you've posted in the iPhone forum.

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.

Connection problems after waking from sleep????

I'm having a strange issue with my 2012 Macbook Pro running OSx v10.8. I take my computer with me between home and school, and I usually just put it to sleep during the commute. For the last few weeks, when I got to school and woke up my MBP, it wouldn't connect to the internet. It recognized the WiFi connection, but did not assign a valid IP address. It was only when I shut the computer down and rebooted it that I was able to connect. Strangely, when I got home, I had no problem connecting to my home network, even after waking up from sleep.
After a little while of this, it got worse. Now, even after re-starting, I am unable to connect at school. (WiFi icon shows exclamation point). This is also true for my home network.
Here's the kicker. When I log out of my default account and log into the guest account, I have no trouble either in school or at home. Waking from sleep is never a problem and I connect everywhere. However, as soon as I log back into my other account, I lose connectivity.
I have tried renewing my DHCP lease, or manually inputting an address, but neither of these have worked. I have resorted to using the guest account, and I want access to my old files again without having to switch back and forth.
If anyone has any input on this, it would be greatly appreciated!! Feel free to e-mail me at [email protected]
Thanks!

same issue here..
reset my network settings and reset phone a billion times already, same issue still occur. sometimes the phone will wake up with wifi and sometimes it will go to 3g, one time it went to GPRS, its just really bizarre. If i open safari it will ask if i want to join the network that i originally set up, but when i select the network it just says "unable to connect". If i just leave the phone be for a couple hours and wake it up again, it will rejoin the wifi network.
I use remote to control my music library, but if my phone goes to sleep, it won't reconnect again so it's basically useless.
BIZARRRRRE, driving me crazy..

Network connection lost after waking from sleep

iMac (27" late 2013) running Yosemite 10.10.
Ethernet connection direct to the computer from the FIOS router.
Upon waking from sleep, the computer is not connected to the internet.
After about 20 seconds it finally reconnects.
Under Mavericks it never lost the connection by sleeping - was instantly connected upon wake up.
I tried creating a new location under the network system preferences and ordered it so that Ethernet was the first to connect.
That didn't change anything.
Any suggestions how to fix this? I don't want to have to wait every time I wake up the computer.
Really bugging me.

Update on my situation.
I have tried many things to get this fixed including:
SMC reset (for an iMac this means unplugging it, waiting, and plugging back in)
PRAM reset
deleted the "system configuration" folder
Still no luck. Upon freshly booting the machine, it gets to the desktop and opens up mail for me, but the internet is not connected right away. Still takes an additional 15seconds or so after Mail boots up to get a connection. Then everything works fine. If the computer sleeps, it doesn't have internet upon waking, but again will establish a connection (self assign an IP address) after about 15-20 seconds.
So while not crippling, these 15-20 second waits are very annoying.
Interestingly, this is ONLY with a wired Ethernet connection. If I use WiFi everything connects right away. But my WiFi is slower than the wired connection and I prefer to use the wired connection.
Any further suggestions are welcome.

Keep losing network connection, especially after waking from sleep, but...

For a while now, my G5 would have intermittent problems not finding the network after it has been asleep for a bit. I used to resolve this by resetting the router, or sometimes putting the Mac back to sleep and resetting the router.
Lately, I discovered another fix: wake up my MacBook. The MacBook wakes up, connects wirelessly, and sees the network, and shortly thereafter, the G5 sees it too.
I cannot interpret this. Why would it be that the G5 would fail to see the router until after the MacBook is awake (and sees the router)? I never could figure out which component was at fault before, and this further confuses me. I mean, it seems that it has to be the G5, since if another computer can see the net on the same network, it would rule out the router and the cable modem. Right?
So what do I do about the G5, then? Yesterday, it was getting to the point where every time I woke up the G5, it wouldn't find the network (until after I woke up the MacBook).

Hi, Brent:
I would not be too quick to start swapping things out (esp. expensive things!) without letting the discussion flow. I have never seen an answer that worked except updates and not all do... see below.
My Dual 2.5GHz G5 has been doing this on and off for years. It has been networked wirelessly since I got it and I am on my third router now for other reasons. I run two other Macs (G4 mini and early IMac/Intel) as well as two laptop PCs, all wireless. None of the other machines ever has this intermittent connectivity issue - just the G5. The symptom is a stalled browser (Safari or FireFox) with the wireless symbol almost always at four bars. Once in a while (like today), the bars will fade down to two for a while, but rarely. Absolutely the only temporary fix I have found successful is to switch airport on and off. Cure may hold for a while or it may not. Have noticed some apps using airport still seem to work (an old MacStumbler utility) even when Safari locks up. Thought it might be a Safari bug, but FireFox does the same thing.
IMHO, this is fundamentally related to a G5 software issue or interaction with the airport or network card. As I noted above, code evolution is a strong factor in my experience. My problems come and go tightly linked to software updates. It is usually a night-and-day change. I am at 10.4.11 on all Macs here; problem had not been around until I ran the last big update to 4.11. Interestingly, my daughter owns a very new iMac with Leopard and has seen the same type of behavior since Day One. I have also seen this problem mentioned about Leopard and iMacs in the lay press.
Wish I could offer a solution, but I am just waiting it out again.

Wi-fi internet connection problem after waking from sleep

hi, i have a macbook pro 5,4 running 10.6.8 OS and i have a wireless issue. whenever the laptop is awkoen from sleep it will take about ~60 seconds to connect to the internet. The wifi indicates that it is connected to my home wifi almost immediately but there is just no internet. Google chrome reports that it is sending a request or redirecting in which it eventually fails to load page. this is very annoying having to wait a minute for my internet to work. i have tried downgrading my wireless card driver/extension to older 10.6.4 as i read there was a wireless issue from 10.6.5 up, but this did not fix the problem. i have also tried changing channels and settings on wireless router with no effect. i do not have any connection issues once the internet connection is established. please help. thanks!

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.

MacBook Pro late 2013 does not show login window after waking from sleep

MacBook Pro late 2013 does not always prompt for login, but opens directly to desktop, even though security settings are setup to prompt for password after 5 minutes. Up to now, this only has happened on battery, machine goes to sleep or lid is closed, 10 minutes pass, lid is opened and desktop is shown instead of lock screen. Console shows, that the machine was actually sleeping (10 min no log entries) and also does not show any error in regards to login window.
This behaviour occurs randomly and I could not track down any root cause/behaviour, yet. Sometimes everything behaves as it should.
Any ideas?
Thanks

Count me in, I have the same issue, and from what I read here, it looks like a Yosemite/SSD related issue ?
I'm not 100% sure if it started when I put a SSD in my old iMac 2009 (as a fusion drive) or if that's after that when I upgraded to Yosemite...
I did disable auto poweroff like suggested in another thread : Mac freeze during the night sleep.
sudo pmset -a autopoweroff 0
We'll see if it helps.
It happens toughly a couple of times a week.

Safari hangs and is very slow to connect initially after waking from sleep

Using Safari and 10.4.8 on a Mac Mini intel core duo
I put my Mac to sleep at night with the hard drive awake. In the morning, I wake my Mac and try to load a page in Safari and it always take about a minute for it to load the first page. Once it does that successfully then it works fine. Just seems that Safari and the network, which is wireless, take an exceptionally long time to wake up.
Any suggestions? I've cleared Safari's cache and rebooted.

Hi alternapop!
Is loading webpages on Safari the first thing you do every morning you wake your Mac? It would seem to be something more related to your network or system getting up and running than Safari? Can you try it out with Firefox or another browser and see if you get the same thing and post back?

My iMac won't automatically connect to wifi after waking from sleep mode

After dowloading the newest software update and performing a firmware update for my Airport router, my Imac won't connect to Wifi automatically after waking from sleep mode

Please re-download and install the 10.7.3 update. You can locate it at 10.7.3 (Client Combo). Follow the on-screen instructions. Then test it out, if you still have the same problem please restart, when you hear the startup tone hold down the Option Key and then choose the Recovery Partition. Then open Disk Utilities and Repair Disk Permissions 2x. Then exit DU, restart normally and re-test.

Ethernet slow to connect after waking from sleep

Since installing Lion (and updating to 10.7.1) on my 2008 24" iMac I have noticed that after waking from sleep the internet connection takes about 10 seconds to restore. I have reset the SMC and PRAM and performed a safe boot (in case this helped) but to no avail. The slow conenction can be observed if after waking from sleep the Network System Preference is clicked and the ethernet status "light" is red, changes briefly to amber and then green indcating a connection. The iMac is connected via an ethernet cable to a Linksys 802.11n 4 port wireless router.
I also have a 2010 13" MacBook Pro, with the same OS, and version, conencted in the same way to the same Linksys router and it does not exhibit this problem.
This slow internet connection access after waking from sleep is an annoyance and I'd appreciate any input on how to elimnate it.
Thanks to those wiser than I, who might read this note.

SOLUTION FOUND!
I've found a list of possible solutions here's the link:
http://osxdaily.com/2011/07/22/wifi-dropping-in-os-x-lion-fixes/
I solved my problem moving the Ethernet and WiFi adapters in the top of the list and Bluetooth at the end.

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.

Network connection after waking from sleep

Hi... More or less any time I allow my MacBook Pro to go to sleep, when I wake it up I am nearly always disconnected from my Airport connection (I connect to a NetGear wireless router via my internal Airport card). I go up to the menu bar and click on the now grey airport icon and I do still see my network in the list of available networks. I click on it, after several seconds a message comes up that says "there was an error joining the Airport network "network name""... But I then simply click on OK (rather than Try Again, I've learned that by trial and error) and the network reconnects just fine... Then when I let the machine sleep again at some later time, I do that all again... Any suggestions of what might be going on??? I do have "Use Interference Robustness" turned on (not that I know why exactly) but I've also had it off before and that seems not to matter... Any suggestions??? thanks... bob..

I have "join preferred networks" selected, and mine os the only one on the list, and it still does not connect after waking from sleep. It is WEP security, not WPA2. I checked out the following article, but it was of no help:

IMac loses WiFi connection after waking from sleep on OSX 10.8.2

Bought a new mid-2011 21.5 inch IMac this week. It is not re-establishing WiFi connection after waking from sleep. Was happening on OSX 10.7 that it came with, so updated to 10.8.2 and same problem exists.
I am running a mid 2012 MacBook Pro with Retina Display alongside, on OSX 10.8.2 and no problems at all. Cannot work out what is causing the IMac to fail and neither can Apple!
Could it be the Netgear Wireless Router 3 years old? Full signal strength!

Me too!
I am on a MAC Pro desktop and I am having the same issues. I go to system preferences and just click the network icon. Then I close mail and when it opens it now sees the network. This is getting very annnoying.
