Mavericks: Wifi takes a while to connect after sleep

Not sure if this question has been asked, but I'm finding this rather annoying. I just upgraded from Snow Leopard and there was a feature where with one simple touch on the trackpad, you can wake your Mac up after the screen goes to sleep after a period of inactivity. I understand that this feature is no longer available after the Lion and Mountain Lion upgrades. With Mavericks, after my Macbook goes to sleep, I push a key and it wakes up, but the wifi takes a while to reconnect, however with Snow Leopard, when I woke up my macbook, the wifi didn't have to reconnect. Is anyone else having this problem? Is this a bug? I hope Apple can come up for a fix for this, because aside from the fact that I can no longer use Pro Tools 9, I'm having free "buyer's remorse" for upgrading.

Nope, turning off my other router made no difference. Even after a couple of minutes of trying to get to any web page after waking/opening the lid it can't find anything online. Had to toggle wifi off/on again to get online.
Apple, please fix this annoyance. Thanks.

  • Security Update 2007-004 v1.1 did not fix connectivity after sleep

    I installed the new security update (2007-004 v1.1) which was supposed to fix airport cards from disconnecting from their wireless network after sleep...but it didn't fix the problem. Is anyone else STILL having trouble?

    I was having the same problem with connectivity after sleep, but once I used the Security Update 2007-004 v1.1 I no longer that THAT problem, but now I have another,....
    in MAIL, there is definitely a 'long' pause before graphics are displayed. Or while using Safari, the text for a new page will display fairly quickly, but again there is a 'long' pause before the graphics show up. I am comparing the time before the first 2007-004 update and now. Before, the graphics downloaded fairly quickly. In the MAIL program, just clicking on an email caused the graphics to appear, in fact, they were just THERE. But now, again there is that longish pause before they appear.
    Has this happened to anyone else? And ideas what I can do?

  • Skype 7.6 (409) Cant connect after sleep/lid-close...

    Skype cannot connect after sleep or after I've closed the lid of the computer. I've tested this out and it sometimes opens up the main skype chat window however I am offline and cannot go online.
    I've tried several methods;
    - deleting $TMPDIR/Skype directory
    - deleting my username folder from ~/Library/Application Support/Skype
    - deleting ~/Library/Application Support/Skype/shared.xml
    - Re-installing skype
    The only solution seems to be restarting my computer so I can relogin with skype. However this is not an acceptable solution.

    I couldn't find the edit button . I've succesfully found the problem causing it. However since I can't debug the skype app I am unable to find a solution as of yet.
    My culprit was vagrant. Everytime I boot up a vagrant instance of a vm (which is whenever I turn on my computer) I get dropped out of skype. I've tested this as far as starting a vagrant during a skype call. The call doesnt drop (it kinda stutters) but I am logged out of skype immediately.
    The things vagrant does are logged here;

    I suspect there is a port misalignment, however the ports I've specified should not conflict with skype afaik.

  • Possible fix for OS X 10.5.7,  losing connection after sleep, restart

    Possible fix for OS X 10.5.7, Airport, losing connection after sleep, restart, or cold reboot.
    Issue: (For OS X 10.5.7 on iMac5,1, Intel Core 2 Duo)
    =============================================
    - After sleep, restart, cold reboot, even though cannot connect to Internet, but the AirPort bars are still full, as if connected.
    - Losing Internet connection after sleep, restart, cold reboot.
    Possible Fix:
    1.Open Network Preference, click on the Location drop down list > Edit Location... > click on the wheel button > Duplicate Location.
    a)Select this newly setup location; Use Diagnostic button to connect to the internet. Select Network or enter WEP password if necessary.
    b)Test to make sure you can connect to a web page.
    c)Go to sleep & wake up.
    d)This time, the Airport bar will start to show correctly. Before, it will always be full even when not connected. Now there will be no bars or grey out when not connected.
    2.On the left hand side of the Network Preference Window, there is a list of services, such as Airport, build-in ethernet, built-in FireWire, bluetooth, etc.
    a)Click on the wheel button on the bottom of the service list; select Set Service Order...; move Airport to the top of the list.
    b)Delete any services which you are sure that you are not going to use, such as Bluetooth, etc.
    3.Pick one of the locations mentioned in #1, and make it sure it is connected. If not, use Diagnostic button. If you have to select Network or enter WEP password to connect, make it so.
    a)Check to make sure you can connect to a web page.
    4.Go to sleep & wake up. The Airport bar should be filled up quickly. Try to connect to a web page.
    5.Restart computer. Test a web page.
    6.Shut down & Start computer. Test a web page.
    7.When everything is working fine, you can delete the extra location that you created in step #1.
    8.Click the lock on the left lower corner of the Network Preference window to safeguard the setting.

    If my assessment is correct, the LIDE 200 driver is version 14.8.1 and dated 26-Sep-2008. It is possible that the driver will not work with the latest version of OSX. I would advise that you contact Canon and ask them the question.
    (Removed link because of the way Flash drives the Canon site).
    It is not uncommon (though irritating) that devices no longer work when an OS is upgraded. One has to ask the question if (or why) the driver was not written in such a way as to be OS version independent.
    Chris
    I spoke to Canon over here in Australia. Not helpful at all. In fact they were about as useful as an ashtray on on motorcycle. Having said that the tech seemed to think that there would be an update soon. But that is assuming that Canon are aware that there is a problem with that Scanner under OS X 10.5.7.

  • Problems auto-connecting after sleep & startup (Changed from WPA to WEP)

    Okay, I know there have been several issues similar to this, but after two days of sifting through posts, I still can't resolve this.
    A few days ago I switched my AirPort network security from WPA to WEP-128. This was required to allow my Nintendo DS to connect to the netwrok, by the way. After the change, two similar, but slightly different problems started:
    My 15" PowerBook G4 no longer auto-connects to the network at startup. The network is listed in the drop-down, and connects with no problem when I choose it manually. The computer seems to have no problem re-connecting after waking from sleep, which is odd because...
    My other PowerBook, a 12" G4, won't auto-connect at startup AND won't re-connect after sleep. As above, it has no problem connecting using the Keychain once the network is selected from the drop-down.
    So far I have tried, on both machines:
    - trashing the system airport prefs
    - deleting and resetting the network's keychain entry
    - repairing the keychain (no errors found)
    - turning off some unneeded power mgt options
    - disconnecting USB peripherals
    I have also reloaded the software on both my AirPort Extreme base and my AirPort Express hub, as well as restarting both hubs. I've also made sure that AirPort is at the top of the network connection list.
    Both laptops are running 10.4.3 and have all the latest software updates installed.
    What am I missing?
    Thanks.

    Both of these replies are helpful, in that they help confirm something I figured out this morning, almost accidentally.
    One thing I didn't mention was that during the change from WPA to WEP I changed the network password. Now, I assumed that since the Keychain seemed to be working and I could get on the network manually without needing to enter the password each time, that meant the new password had correctly propagated throughout the system.
    So, this morning I go into the Network settings, switch from Automatic to Preferred, select my network, look at the properties, and notice that somehow it has way too many bullets for that to be the correct password. I re-entered the password and that seems to have solved the problem. The new password I had entered somehow didn't make it into this setting. I guess trashing the network prefs, or renaming the network would have had the same effect.

  • T440s in Windows 7 Pro loses Wifi connection after sleep 7260AC

    Hi guys,
    I keep having issues waking up from sleep with my T440s.  It WILL NOT connect to wifi and the wireless adapter under windows adapter settings disappears.  Only thing that fixes this is a reboot.  I have removed "allow windows to turn this device off" under wireless settings.
    Driver: 17.12.0.4
    Dated: 28/08/2014
    Software: Lenovo Access Connections
    I do not use windows to connect to WIFI.  I have dedicated profiles for each of my wifi networks at home and work.
    This is a serious productivity killer.
    Any help would be appreciated.
    Thanks!
    Solved!
    Go to Solution.

    This is a well-known issue with the AC card.  Go take a look at the Intel forum.
    You don't necessarily have to reboot to get the card back.  Right click it in Device Manager and then disable/enable.  It will come back online.
    Some tips that have worked for many:
    -DO enable the power saving setting.  If I disable it on my T440p, the card is offline upon wakeup. 
    -Ditch ProSet and let Windows manage your wifi.  Profiles might be convenient, but...
    -Ad Hoc QoS - WMM enabled.  Enable it on your router(s), too.
    -Ht Mode - VHT
    -U-APSD support - this one can go either way.  Some leave it on and don't have an issue.  Some have to disable it to have the card work after sleep.  You have to play with it. 
    And, I really believe that the router/modem type can make a difference, too.  Some just don't work right with this card no matter what you tweak on the card.  With this card, I think an AC router/modem is the way to go. 
    Another thing is the driver itself.  I had wake issues when I first got this ThinkPad about 10 months ago.  Then, Intel released v 16.6 and that one fixed it.  I've tried all of the 17s released since and all of them caused sporadic failures to wake.  So, I have always rolled back to 16.6 and it always wakes. 
    Note this:  If you use Lenovo Update, it won't create a restore point in Windows so your "Roll Back Driver" button might be greyed out in DM.  Always manually create a restore point before you update a driver.  And, if it's working, whatever it is, leave it alone.  If the release notes don't address an issue you're having, skip it. 
    Driver updating is way oversold here and elsewhere.  If you're determined to update anyway, at least don't be an early adopter.  Let other peeps do it first and then come back here and see about the complaints!  Also, you can download the driver at Intel in their Administrators sets of drivers.  Bare drivers and no software overhead. 
    Good luck.

  • PB G4 takes a while to connect

    Ever since I installed my Extreme 802.11n, my PowerBook G3 (1.33 GHz) can take up to 12-13 seconds to connect after everything appears to be fully loaded (i.e., after top menu bar including clock, battery, etc appears.). Is this common? Here are some additional details:
    - I also have a MacBook Pro that connects right away
    - Prior to having the new Airport Extreme, I had a 2Wire Modem/Router (which died for the second time) and I did not experience this problem. It would always connect right away.
    - Upon installing the Airport Extreme, my PB G4 would not automatically connect. I had to do this manually. After talking with support for quite a while, we ran disk utilities, found an error, and we repaired it. This was done from the install disks). After this, it would connect automatically... but only after this delay that I currently experience. Btw, if I'm in the same room as the Airport Extreme, then it's faster (2-5 seconds).
    - If I go to my detached office, where I use an Airport Express to extend my network (I have a roaming network), then it connects right away. Granted, it's in a small office and my Mac is only feet away from the Airport Express. So that might be a moot issue. But I thought it could be relevant.
    - I can tell when it's about ready to connect. When I power up the Mac, and every thing appears to be loaded (spotlight, clock, battery, etc.), my Mac is quiet. Then after a 5-13 seconds, I hear my hard drive start to process again, and then, finally, my airport connects. It's as if it's doing one last "start up" routine and then it connects.
    So my question is, how common is it that it may take my PowerBook G4 10+ seconds to automatically connect after eveything else appears to be loaded?
    If not, is there anything I can do to help speed this process up?
    PowerBook 12 + MacBook Pro   Mac OS X (10.4.9)  

    Make sure devices and desktop app are running on the same Wi-Fi. Also try to connect manually by entering the IP address of the machine where Edge Inspect CC app is installed.
    If this doesn't help, please let me know the exact problem which you face.
    Any error message in the Chrome extension's console?

  • Wifi needs up to 30 sec. to connect after sleep

    The title exactly describes the problem. The wifi  connection of my  MAC book pro (late 2013)  will take up to 30 seconds to  connect to my WLAN after sleep. Maybe it is a problem since Yosemite but I don´t know exactly. Does anybody has the same problem or maybe a solution?
    Regards, Lidira

    There are many factors in startup time. The first time you create the engine there should be a short delay as lots of things are going on, dlls are loaded, global variables and configuration files are loaded and internal data structures are created. When Start() is called, additionally the loginlogout callback might be launched. 20-30 seconds does seem a bit long though for any modern machine (I'd expect more on the order of 2-5 seconds on a reasonably fast computer for creating the engine) so something else might be going on in your system. Do you perhaps have a lot of global variables, are a lot of VIs being loaded by the loginlogout callback perhaps and perhaps being mass compiled by labview? Is your login callback perhaps hanging on an instrument driver call until a timeout occurs? There are many many possibilities. Have you tried launching a UI or seqedit.exe on a clean install of teststand on that machine? If so how long does that take? If it's much faster than 20 - 30s, then the extra time must be due to customizations you have made. If so, try systematically removing or commenting out customizations to narrow down where the problem is. If on a clean install of teststand it still always takes 20-30seconds to create the engine, then there might be something unusual about your machine that will need to be narrowed down (assuming it isn't just an usually old or slow computer). Have you seen this significant a slowdown on all of your machines or only on certain ones?
    Also keep in mind that the OS does lots of caching of things, so the first time dlls are loaded is often much slower that subsequent times.
    Also keep in mind that .NET applications startup slower than non-.NET application (especially the first time one is launched after rebooting) as there is a significant amount of overhead involved. This is something Microsoft has been working on improving for future versions of the .NET framework.
    Hope this helps,
    -Doug

  • No wifi re-connect after sleep - It's caused by Bluetooth!

    After upgrading to 10.5.3 my Air would no longer connect to my wifi network after sleep.
    I have made no system chnages and it always worked before.
    After much testing......
    Turn Bluetooth off, problem gone. My Air reconnects to my network after wake.
    Turn Bluetooth back on and it no longer connects after wake.
    Can anybody else confirm....
    Would could be causing this and how is it fixed?

    Hello,
    I have been having a large amount of problems on my MacBook (Tiger) when trying to re-connect to wifi after sleep (lid and button), to the point where using prefs>network, I couldn't even connect. I could sometimes get it to reconnect with a full reboot but the was intermittent - my issue was predominately on N (which I use a lot) although G was very flaky with a lot of connection dropping also.
    Have tried everything, went to the Mac Store and had a new logic board and Wifi card
    Upon returning from the MacStore the sleep issue was still a problem and having read this post, I played around with my bluetooth and found that after sleep it started to reconnect again intermittently in either Off, On (not discoverable) and On (Discoverable). I then by chance realised my wireless keyboard was in the cupboard close by. I turned it off and reconnected it and it seems to have cured my problem. I have yet to try with keyboard on but in the past when it has been in permanent use I have never had an issue. So try resetting your bluetooth and your mice and keyboard and doing a full reconnect.

  • Mac loses wi-fi connection after sleep

    Since I upgraded to Mountain Lion, every time I wake my Macbook from sleep, I have to manually reconnect with my wi-fi router, and sometimes it takes upwards of a minute before Airport even senses the various routers within range, includng mine. Before upgrading, when I woke it up, the connection was just there, instantly, for all intents and purposes.
    What's up? Is there a setting that I need to adjust?

    The loss of connection to wifi after sleep is nothing to do with the TC at a guess.. but typical issue with sleep and wireless.
    See the methods of repair for this that Tesserax has prepared.
    https://discussions.apple.com/docs/DOC-3411
    I presume the upgrade was to Mavericks.. it does have some network issues.
    I would certainly use all SMB naming. Mavericks now uses SMB network protocol by default.
    So SMB names are not like apple names.
    They are short.. keep to less than 20 characters.. less than 10 even better.
    No spaces and pure alphanumeric.
    Use only WPA2 Personal security with a 10-20 character purely alphanumeric password.
    Finally it can be worthwhile using fixed wireless channels.. test say 11, 6, 1 or whatever you have available in Russia. Same on 5ghz use whatever channels are available but try a low one if possible.. eg 40 and a high one like 149.
    I strongly recommend you setup the TC this way.. and use separate names for 2.4 and 5ghz at least until you get it sorted.
    eg.. TC name.. TC
    2.4ghz name.. TC24ghz
    5ghz name.. TC5ghz
    Then as per Tesserax, clear out all the old names. So you have a clean slate and only use the TC on one band.. try each and see if it is reliable.

  • Airport after 10.4.2 Will Not Connect after Sleep

    After my iBook G4 goes to sleep it will not reconnect to the internet.
    It shows connection.
    It shows me the IP.
    It will not allow me to do anything online.
    I have to quit all internet prorams mail, safari, firefox etc...
    Then I have to reset the location over and over and try until it works. Sometimes right off the bat sometimes it takes 10 minutes. This is completely frustrating since even the network diagnostic is showing internet, ISP, etc.
    I've rebuilt my keychain.
    I've rebuilt the WEP password
    I've changed my computer name to be one word no spaces.
    I need help! My wife cannot use this computer if it won't connect without interaction. I never had this issue before 10.4.2 was installed.

    Henry,
    Thank your for the helpful link.
    I created a new location based on the info in the link you provided.
    It worked.
    Now, the iMac G5 rejoins the network automatically after sleep or restart.
    I don't know if level 4's need point, you and Frank C. (author of the info at http://discussions.info.apple.com/webx/.68ae4ead) just got some more from me.

  • Apple TV loses connection after sleeping

    My Apple TV had virtually no problems with a connection when being used, but has this curious quirk of losing it's connection after an extended sleep period. It seems as if it sleeps for more than 8 hours, it will no longer be connected to my network. Viewing the settings for the Apple TV, it shows that my connection should be working and has full strength, but doing a test results in nothing happening. My options are restart or drop connection and input my network password again. This gets really annnoying, because almost everytime I want to use it, I have to do either of those things first.  Are there any internet settings I can chnage so that this stops happening?

    Actually same goes for the iPhone after charging it when I sleep, next day, have to turn wifi on and off to get the connection to work properly.

    I was having the same problem but think I have found a solution. So far I have put my Macbook to sleep about 6 times and I can still reconnect to my network servers.
    I found the solution here: http://forums.macrumors.com/showthread.php?t=518958
    Here it is:
    1. Open network preferences from your WiFi icon in the menu bar. Then click advanced. Delete the network that is giving you problems.
    2. Open Keychain in the utilities folder of your hard drive. Find the passwords that are stored for your particular network and delete them. There may be multiple passwords for your network, so search carefully.
    3. Repair permissions using the disk utility.
    4. Reboot the computer.
    5. Reenter your network data to log into the network.
    Good luck!

  • My iPad (1st gen) loses Wi-Fi connection after sleep.

    If my iPad is allowed to go into "sleep" mode on its own, the connection to my Wi-Fi network is lost.  Going into the iPad settings and toggling Wi-Fi off and back o n will restore the connection.  I don't have to re-enter the password for the connection to be restored.  This doesn't happen with any other devices on my wireless network.  Any suggestions on how I can resolve this?

    I was having the same problem and could only get it back either by restarting iPad, clearing the network or restarting the Router. I eventually found this useful post on the Princeton Universty website:
    http://www.net.princeton.edu/apple-ios/ipad-iphoneos32-dhcp-workaround.html
    It appears the problem is caused if you have any applications which uses Push notifications such as Mail, Contacts, Games Centre etc. Apparently in IOS 4.3, when the iPad goes into sleep mode it should drop the wifi connection to clear the DHCP cache. If you have notifications on, it doesn't drop the connection on sleep so when it wakes up again, either the DHCP cache entry is out of date or something else is out of step with the router.
    This only happened after an abortive attempt to upgrade to IOS 5.0.1 (see https://discussions.apple.com/message/16778153#16778153)  and a downgrade to IOS 4.3 which I think is where Apple introduced the Games Centre with notifications turned on by default.
