Mid 2012 Retina Macbook Pro, 15 inch - as title suggests, after recently installing Mavericks from the app store + doing an upgrade install, the thunderbolt ethernet adapter no longer comes back online after the laptop wakes from sleep. System Information shows that the device is present and connected, it just won't bring the network interface up, so I have to disconnect + reconnect the adapter to get networking back up.

 

Wifi works fine, no problems there.

 

Anyone else encountered a similar issue?


MacBook Pro (Retina, Mid 2012), OS X Mavericks (10.9)

    I have exactly the same issue, I have to unplug the adapter and the reattach it and shortly afterwards ethernet reconnects, most annoying.

    Yes, I too this issue to deal with (in front of a client no less!) after updating to Mavericks.

     

    What worked for me:

     

    System Preferences > Network > with Thunderbolt Ethernet highlighted, click Advanced > IPv6: change to Link-local Only > Hit Renew DHCP Lease > OK > Apply.

     

     

    Please let me know if this worked for you guys too.

    Thanks HK, after doing that, it has started coming back automatically after waking. Excellent!

    Thanks for this discussion - more infos:

     

    Around same context after 10.9 updating : iMac 27" - Thunderbold Giga Ethernet adaptor - IP set Manually -  Same issue after sleeping and waking - no recovering of internet connection and to router.

     

    I test HK solution (IPv6 Local link Only) :

    - with IP manually set : no recovering of router and internet connection after waking

    - with DHCP using manual address : no recovering of router and internet connection after waking

    - with DHCP : Ok, recovering of router and internet connection after waking

     

    Curious issue... but manual address temporay unusable until 10.9.1 next release and when ???

    I can confirm that this has fixed it for me too, even though I'm using a non-DHCP static address. Thanks HK.

    Hi,

     

    Similar problem - 2013 Macbook Air  - connected to Belkin Thunderbolt Express Dock (which has its own gigabit ethernet adaptor), every time the system sleeps-wakes it loses network connectivity. I have to physically pull the ethernet cable from the wall and replace to get the connection to come back up.

     

    Note that this is despite the network adaptor showing as coonected in System Settings -> Network.

     

    I'm really not sure what to do about this.....should I contact Belkin or Apple....?

     

    Cheers, Jon

    I want to say Apple are the best people to contact, given that it's affecting all sorts of thunderbolt connections including purely first-party devices like Apple's own thunderbolt ethernet adapter, although one sniff of the word Belkin and they'll probably suggest you take it up with them.

     

    In addition to earlier, HK's solution did work for me - but only with a purely DHCP connection. Like calitinilo, if I'm using a static IP setup, I still need to either reconnect the controller or swap network locations (either from the GUI or scselect in a terminal window) to get the link back up.

    I am getting the same issue with Mavericks, thunderbolt ethernet and fixed IP address being lost after wake. Can't use the ethernet through the Apple thunderbolt display.

  • MaximusAT Level 1 (0 points)

    I have the same problem. Static IP and no connection after sleep.

  • MaximusAT Level 1 (0 points)

    I have to add that this happens only when the MacBook Pro is on battery. If the power cable is plugged in, the connection is resumed after sleep.

  • angrypanda Level 1 (0 points)

    Not for me - doesn't matter if the MBA is on mains or battery power, same behaviour.

     

    go to sleep -> wake up MacBook -> no network

     

    Bloody frustrating.

     

    Cheers, Jon

    Same problem on my new Retina MBP... hopefully 10.9.1 fixes this

  • kokni Level 1 (0 points)

    Same here, 2013 mba,  thunderbolt to ethernet with static IP shows connected and supposedly functioning but no network connection after going to sleep. The trick with ipv6 did not help. I must unplug and re-plug the ethernet cable.

  • harabai Level 1 (0 points)

    same here, just got my MBP yesterday, and using it today at work. man i hope they fix this flaw, can't believe they didn't catch this **** in QA
