Q: Losing network or internet connection after sleep/wake

I've created this as a new thread as it seems to be more prevalent with Mavericks and the very last update to ML but the problem has been around a while. It does seem to affect all types of Mac though from the other threads I have read and posted to.

 

The problem is essentially this: Intermittently, after a system sleep, the Mac appears to have no network connectivity (local and internet) and for a while the only reliable solution was to force the renewal of the DHCP lease or turning WiFi off and on again, after which the network would be restored.

 

There have been several theories postulated and a number of fixes, such as the DHCP renew, suggested but none of them have lasted for long but I now think I have this fixed as the following been 100% stable on my Mac Pro with wired ethernet connection for the last two weeks with no recurrences. I see no reason why this would not work on other Macs or connection types.

 

The problem seems to lie in the automatic location setting in the network settings, so here's what I did...

 

  1. Network settings - Location - Edit Locations
  2. Add a new location .. "Home" for example
  3. With home selected, click the cogwheel below the network services and choose "Set Service Order"
  4. Reorder the services so your preferred connection type is at the top
  5. After that, select each service in turn (assuming you have a few - like Bluetooth PAN etc)
  6. Make the services you are not using inactive
  7. Apply

 

Please post a reply if this works for you - it's been dragging on far too long and needs sorting out by Apple but if this is a good workaround for people then it will certainly do for now.

Mac Pro (Mid 2010), OS X Mavericks (10.9)

    you might try a less drastic solution:

     

    - system preferences

    - network

    - disable service...then apply

    - enable service...then apply

    None of the solutions mentioned here have worked for me. My Macbook Air is the only device out of several macbooks that is having issues, and the problem started immediately after upgrading to Mavericks. I did not have any problems after the Mountain Lion upgrade and am still using all of the same equipment. I definitely do not recommend upgrading to Mavericks until Apple published an update specifically addressing this issue. None of the features advertised in this new release are worth the headaches and constant inconvenience.

    It's a bit hit and miss for me. My MBP is having problems as is one of my colleagues. Two other colleagues are fine, as is my MBA. Not sure why things are so hit and miss, but the problem is a killer for my productivity.

    It worked like a charm!  Many thanks for posting this solution, Reforger!

    Not sure if I am having the same issue, occasionally while using Chrome I get the message resolving host, all network connectivity is lost. Sometimes it comes back, sometimes not, renew DHCP release seems to work. BUT, I should not have to do this.

    This happens even in the middle of using my computer, it's not just when it falls asleep. In fact my power management is disabled, there is no sleep mode.

    I am trying this.  I had no probelms until I upgraded to Mavericks.  My question is this:  I use my MacBook Pro for business on the road.  Do you know if it might still find WiFi services automatically in my new Home mode or will I have to switch back to Automatic?

    If you check the box "Ask to join new networks" which is on your Network Preferences dialog, it should automatically find new wifi networks that are in reach.

     

    If you leave the box unchecked, then you would have to manually connect to new networks by using (1) the "Network Name" pulldown box, (2) selecting "Join Other Network" and then (3) "Show Networks" to display which wifi networks are available in your immediate area.

    I definitely think this is a Mavericks issue.  My iMac running Mavericks is the ONLY system in the house that drops the network randomly while all other systems never lose the network.  No idea how to resolve this, but here is the workaround I'm posting: 

    I've had the 'network drop' issue with my Airport Extreme for the last 2 months.  It reconnects when I pull the ethernet cable and plug it back in.  I've tried downgrading the AE firmware, resetting to factory, etc.  Nothing worked.  I finally threw in the towel and created a script that monitors my network connectivity and restarts my interface if it senses it has dropped:

     

    ##############

    #!/bin/ksh

    while true

    do

      yup=`ping -c1 -t2 www.google.com|grep from`

      if [[ -n $yup ]]

         then echo "Internet is connected!"

      else

            ifconfig en0 down; ifconfig en0 up

            echo "Down at `date +%m%d%Y%H%M%S`">>./dropped.out

      fi

      sleep 5

    clear

    done

    ###############

     

    I know its a workaround, but its saving me the headache of constantly pulling my cable and putting it back in!

     

    Good luck!

    Great idea! If we can find out when it happens we may be able to find somehing in Console. I am going to try this out, thanks. Also, my Mac is also the only one that has these random issues. Of counrse my Mac is one that I also had to replace the display within a year and then the logic board went out right after the warranty so I am not too surprised of another issue. People often say how great and reliable these machines are bit I have had nothing but problems with this and the amount of money it takes to keep it running make me wonder if it's worth it. Perhaps a cheaper more reliable $300 linux machine will be my next machine the next time a major component fails on this POS.

    Well I've had zero luck trying to correlate the drops with anything in the logs.  But it definitely happens more often when I'm doing more intense network traffic like RDPing into work.  Unless we could get into debug mode on the AE, we may be out of luck trying to troubleshoot this.  Right now the script polls every 5 seconds, but I may have to bump it up to 4 or 3 seconds.  Very frustrating!  Please post if you find anything!

    Did you try creating a new Location ? It had a dramatic effect to reduce my network drop out rate.

    I removed all my previous locations, created a new one, and turned off bluetooth. Finally, my Macbook Air has been working as it used to before upgrading to Mavericks i.e. when I open the lid it connects to WiFi instantly and it can now find a signal that it was already using before I closed the lid. I have had several days of repeat success at home and away from home.

     

    When I turn bluetooth on the problem returns, so now I have a toothless computer thanks to Mavericks. Good thing I like the trackpad. After the last few weeks, I now see many many threads here when searching for WiFi Mavericks issues. It seems to disingenious for Apple to host these discssions without reading, consolidating, moderating oor acknowledging a problem in any way. For those of you here, thanks for keeping the discussion going and sending your feedback, and thanks for letting me vent.
