Wifi is not auto connect after resume from sleep

I keep my Mac Book Pro up-to-date with software updates.
I recently update to OS X 10.8.3 (12D78).
Since then when I open my laptop after closing it and put it to sleep the wifi connection does not re-connect automatically.
I have to click on the wifi sign near the clock and select the network to connect to.
How can I make it connect automatically like it used to?

Wifi problems seem to crop up a lot on here and unfortunately there doesn't seem to be a 'one fix' solution.
However, sometimes any one of the following can help although, unfortunately, not always - in no particular order:
Check wifi security - if it's WEP change it to WPA or WPA2 (preferably, as it's more secure)
Change the wifi channel on the router
Create a new Network Location: http://support.apple.com/kb/HT5289
Reboot the router
Also take a look at this link and the links within the article for other ideas. They mainly reference Lion, but still seem to be relevant to Mountain Lion:

10.9.2 upgrade and now wifi will not automatically reconnect after wake from sleep

I upgraded to 10.9.2 on my mid-2012 Macbook air and now when i wake the laptop from sleep the wifi will not automatically reconnect. I have to physically click on my network to re-join it.

Test after taking each of the following steps that you haven't already tried. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved. Make sure the box marked
Remember networks this computer has joined
is checked.
2. Follow the instructions in this support article under the heading
Symptom: After restarting or waking from sleep, my computer might not connect to the Internet
3. Reset the PRAM.
4. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
5. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
6. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
7. Repair permissions on the startup volume.
8. Turn off Bluetooth and test.
9. Reset the System Management Controller.
10. Reinstall OS X.

Lenovo G770 Fan not spinning up after resume from sleep or hibernate

Hi guys,
My lenovo G770 is facing an issue where when ever I resume the system from either sleep mode or hibernate, the fan does not spin up, as a result I have to either restart the system or open the system, pull the wire of the fan and put it back in the power socket.
Lets make 2015 the year of the #DO
Did I or someone help you today? Press the star on the left to thank them with a Kudo!
Solved!
Go to Solution.

Hey Abdul,
Welcome back. If the fan runs normally on first boot until you suspend / resume, then I might imagine this is power management quirk, or something confused in the embedded controller.
1) Try going into BIOS and reload defaults - this might refresh values there.
2) Try uninstall / reinstall power management driver and the energy cut software (Idea power manager).
Did you recently update BIOS or drivers?
I would also try some temp monitoring software just to see how CPU temps run after you come back from sleep to see if the fan should be running.

Ethernet not connecting when resuming from sleep/hibernate

I use my mac (Win7) in clamshell mode quite often, and I leave the cables connected (ethernet, power, display, etc). I have noticed since installing the 3.0 Boot Camp drivers that the ethernet connection is not recognized after resuming from sleep/hibernate. I need to disconnect the cable and re-plug it in for the system to recognize the network. Anyone else seeing this?

Look through Power Options for sleep and network. There should be sleep, low power, etc. And if possible, maybe you can manually update drivers from the vendor (not Apple). And if Windows or your update doesn't work as well, then you can just as easy use Device Manager and "rollback" the last driver upgrade - a great feature. Also, use those Create/Restore Check Points.
I use to have trouble, got tired of having this issue, and bought a new modem to replace my 5 yr old model. Problem gone. Same can happen regarding routers, sometimes a firmware update, but I had one router that had been superceeded by 4th generation and no firmware patch anymore.

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.

MBA loses internet connection after waking from sleep

I have a new Macbook Air running Mavericks and new 802.11ac Airport Extreme router.
My problem is that the MBA drops the internet connection after waking from sleep. I tried the solution offered by the OP, but it didn't work.
In my case, here's what I have to do to get a connection again. I open the Network preference pane, and then choose "Assist me..." and then "Diagnostics". Invariably it will show a green light beside Wi-Fi, Wi-Fi Settings and Network Settings. I have 5 bars showing in the WiFi menu bar icon. But ISP, Internet and Server will be yellow.
When I go through the steps prompted by the wizard, the ISP/Internet/Server lights turn green on the third screen where I select the wireless network I want to join.
It seems as if it's connecting to the WiFi network when it wakes from sleep, but losing the internet connection?
Note: I have a new iMac as well running Mavericks and don't have this problem with it.

If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

Update to 10.6.8 - system hang (mouse issue) after resume from sleep

I am on older
MacBook Pro3.1
Intel Core 2 Duo
2.6GHz
Run on 10.6.8 almost flawelessly. Shortly after upgrade to 10.6.8 system started to hang periodically after resuming from sleep. Symptoms are that it stops responding to mouse (be it touch pad or USB mouse). Keyboard seems to be ok but system doesn't seem to be fully functional. I am able to ssh from the other computer and 'shutdown -r now' after reboot system seem to be ok until next resume from sleep. What interesting though is that this problem newer manifests then I am using external monitor.

Found problem. It was due to magic mouse that I left on. I carry this mouse in the laptop bag but rarely use it. Last time I used it (around the same time I install the update) I left it on in the bag. It was apparently disconnecting/connecting on its own and by some reason sometimes was breaking touch pad and other usb mouse connected to laptop, as soon as I switched magic mouse off broblem was fixed

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..
FW800 G4 dual 1.25 Ghz and 17 inch MacBook Pro Mac OS X (10.4.8)

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:

My Mountain Lion mac crashes after resuming from sleep

Hello
My Mountain Lion mac crashes after resuming from sleep every time I use it
It happens every time the mac resumes from sleep and it started like a week ago
I remember installing the new updates for flash? and xquartz and nothing else.
I have also had microsoft word installed on my mac for about 1 weeks before this problem started so might be related to that
Please share with me any tips on how to fix this because I am really annoyed of losing stuff after each time my mac resumes from sleep

I have an iMac bought may -11, and it worked fine with Snow Leopard.
About a week ago I bought and installed Mountain Lion 10.8.2. Everything went fine, and all software worked ok. iPhoto had some problems, but after installing update the system prompted to do, it has worked ok.
The propblem occurs now and then, when computer is waked up from sleep. The Desktop occurs, but no software starts, not even System Tools untlil rebooting the computer. Of course, I can not reboot the computer from "Apple menu", but holding the power button down.
This is very embarassing! OsX Mountain Lion has turned out to be a very big disappointment. I installed id because of iCloud (i have a new iPad, too with iOs 6 installed).
Can anyone help me? Is there any other way to solve the problem than re-installing good old Snow Leopard?
I would not like to do that, I bought Mac because I was bored in re-installing and recovering!
Thank you

Slow LAN Networking Speeds after Resuming from Sleep

I use my mac mini as a HTPC running Plex. I have it connected to my Windows media server with 802.11n. Works fine but sometimes after resuming from sleep the network speed drops off to an unacceptable level (from 72 Mb/sec to 5 Mb/sec). Disconnecting and reconnecting doesn't help. Switching to G doesn't help. Only restarting the mini restores the connection to full speed.
None of my Windows clients on the same network have any troubles.
Thoughts?

Looks like Plex might be causing the problem. I always have plex running and it appears as though if Plex makes a request for a file on the share before OS X is done re-mounting it after sleep, it kills the whole process.
Shouldn't the OS be robust enough to handle a situation like this?

No connection after waking from sleep using Express as base station

I find it difficult to re-establish my Internet connection after waking from sleep.
The Airport Express is connected to a wired Linksys router. I am using the Airport Express as my main base station. The Powerbook is joining my preferred network, but I am unable to get any in- or outbound Internet traffic.
I am, however, able to connect to my Linkys and login to to its admin area. When I run Ping and Traceroute diagnostics from the Linksys web interface, everything seems to be fine-- I am able to see outside servers. So the problem is this-- I am losing my Internet connection somewhere between the Linksys router and my Powerbook. Only after I fiddle I reset the Airport Express and fiddle with the Airport menu (Turn Airport On/Off) am I finally able to get out to the Internet.
I have the channel switching set to Automatic, but I've also tried running the Airport Express at different channels to no avail.
Has anyone experienced similar problems?

Since you have an Airport Express connected to a separate router, start by disabling the router built into the Airport Express. To do this - run the Airport Admin Utility, select your Airport Express, click Configure, click the Network tab, and uncheck the setting to "Distribute IP addresses". Update settings to the Airport Express. Then - very important - restart all wireless computers.

Browser not connecting after returning from sleep, but email and imessage working fine

My Browsers are not able to access the Internet after returning from sleep. This effects other browsers (Firefox & Chrome) as well. The connectivity from mail and iMessage is working fine. I am also hardwired and not using WiFi.

I have the same problem since updating to Yosemite, works fine after restarting but once it goes in to sleep it affects email as well as browsers, I have a broadband connection. Also accessing the app store is hit and miss, it's either working or simply not not working.
It also affects other devices trying to connect to the internet over wifi via the airport time capsule, the problems started after installing Yosemite.

Wifi Lost and Network Preferences Inaccessible after Resume from Sleep

Macbook Pro, shipped with Lion.
I've had a problem when Lion resumes from sleep of not being able to access any networks. Specifically, the wifi symbol in the menu bar shows the pulsating waves, when clicked it reports that it is searching for networks, however it doesn't find the standard wireless network it is normally connected to at home, nor can I choose any further options in that dropdown menu. Specifically, I cannot access Network Preferences, via any GUI based method (don't know enough CLI to know how).
Most alarming is that this has happened in a couple of different scenarios:
1) normally putting the laptop to sleep if 2 different users are logged in via fast user switching
2) if the computer shuts itself down from the sleep position because it has been unplugged for too long.
Restarting does revert everything back to normal, but I was hoping for a less drastic fix. Sorry to gripe, but I'm especially disappointed because I'm a mac newbie, and between this and other problems, have had to restart this mac due to spinning pinwheels of death and the like more in 2 months than I ever have a Sony Vaio Z running Windows 7. Kind of disappointing that Mac has the less stable operating system.

That's awkward. It may not be the Mac itself making it unstable, but yet programs on it making it unstable (lazy developers maybe). Although do remember that OS X Lion is fairly new, and a few bugs are still being ironed out.
First thing you should do is Repair permissions. Open up Disk Utility, Chose your disk on the Left and click on the Repair Permissions button. This can take about 20 minutes and fixes most problems.
Questions:
Have you installed any additonal system prefence panels?
Have you installed any programs that alter with WiFi?
Does your WiFi Access point have enough strength for where you are?
If you have installed addional system preferences then I suggest that you go to Finder, and in the top bar click on "Go" and navigate to "Go To Folder". In that box put this: "~/Library/PreferencePanes" (No quotes though - and remember the "~" ).
It'll take you to a folder, copy those into a safe location and remove the contents of that folder.
If you are an Administrator of your computer then do the same in "/Library/PreferencePanes".
Hope all goes well! Good luck!

NetworkManager - no wired connection after resume from suspend

Similarly, running 'sudo systemctl restart NetworkManager' doens't help as I only get a wifi connection. Journal messages are pretty much the same as above. I'm trying to determine if this is a driver issue, but I don't see anything relevant in the journal. I've seen a couple of bugs on the Debian bug tracker https://bugs.debian.org/cgi-bin/bugrepo … bug=743206. That one appears to be solved as " network-manager 0.9.8.8-6". I currently have 0.9.10.0-1.
Interestingly, sometimes when I try and restart networkmanager from gnome's menu, I see
dhcpcd[8545]: dhcpcd already running on pid 8330 (/run/dhcpcd-enp2s0.pid)
After running 'sudo systemctl stop NetworkManager' followed by 'sudo killall dhcpcd' and 'sudo systemctl start NetworkManager' I get wifi but no wired connection. Anybody have any ideas?
EDIT: Any suspicions against dhcpcd are unfounded as behavior using dhclient is not much better. After wake-up I apparently do have a wired connection, but pings to 8.8.8.8 and www.google.com both fail. Restart networkmanager using systemctl does not work as with dhcpcd. Stopping networkmanager, killing all dhclient processes and restarting networkmanager do restore my connection to the internet though. Sorry for my scatterbrained attempt at troubleshooting this. My difficulty here is pinpointing an exact sequence of steps that results in consistent behavior. So far, after waking from sleep any of my above attempts at getting a network connection have varying degrees of success and failure.

Similarly, running 'sudo systemctl restart NetworkManager' doens't help as I only get a wifi connection. Journal messages are pretty much the same as above. I'm trying to determine if this is a driver issue, but I don't see anything relevant in the journal. I've seen a couple of bugs on the Debian bug tracker https://bugs.debian.org/cgi-bin/bugrepo … bug=743206. That one appears to be solved as " network-manager 0.9.8.8-6". I currently have 0.9.10.0-1.
Interestingly, sometimes when I try and restart networkmanager from gnome's menu, I see
dhcpcd[8545]: dhcpcd already running on pid 8330 (/run/dhcpcd-enp2s0.pid)
After running 'sudo systemctl stop NetworkManager' followed by 'sudo killall dhcpcd' and 'sudo systemctl start NetworkManager' I get wifi but no wired connection. Anybody have any ideas?
EDIT: Any suspicions against dhcpcd are unfounded as behavior using dhclient is not much better. After wake-up I apparently do have a wired connection, but pings to 8.8.8.8 and www.google.com both fail. Restart networkmanager using systemctl does not work as with dhcpcd. Stopping networkmanager, killing all dhclient processes and restarting networkmanager do restore my connection to the internet though. Sorry for my scatterbrained attempt at troubleshooting this. My difficulty here is pinpointing an exact sequence of steps that results in consistent behavior. So far, after waking from sleep any of my above attempts at getting a network connection have varying degrees of success and failure.

Wifi is not auto connect after resume from sleep
