Q: After Lion upgrade, having network issues after wake from sleep

After upgrading to Lion from 10.6.8 on my MacBook Pro (15-inch, Early 2011), I am unable to connect to the Internet after the computer wakes from sleep.  I should rephrase this - I am able to ping IP's and DNS (DNS servers are present) however none of my apps will connect (Safari, iChat, etc) -> they all indicate the Internet is unavailable.  I have two Airport Express's running 7.5.2 extending a WiFi network off an Airport Extreme running 7.5.2.  This issue is specific to waking from sleep.  Any thoughts or suggestions would be appriciated.

Mac OS X (10.7)

    Yesterday I was able to fix the issue by making a change to my network settings (late 2009 i7 iMac w/ manual IP on ethernet), I simply changed IPv6 settings and saved, and magically my interwebz were accessible to apps other than terminal.

     

    Today I had to log out my account and log back in to resolve, as changing network settings didn't seem to help.

    Exact same problem here.

     

    I had the issue with Snow Leopard and it is now much worse after upgrading to Lion.

    Been having the same issue made a post earlier today detailing it https://discussions.apple.com/message/15705639#15705639

     

    For me this is the most irritating bug ever, having to check that you're not backing up before closing the lid is ridiculous.

    Same problem here with eth.

     

    Every time I wake up my iMac from sleep I need to logout/login in order to get the internet working...

    The solution for me was to make sure my Airport's were correctly updated - one was running 7.4.x - after upgrading to 7.5.2, it fixed the problem!

     

    I've got the same problem but I'm not using the Airport at all...

    It's definitely linked to Time Machine and backups.

     

    I have the same problem but I have disabled Time Machine, so I don't think it's related to that.

    Try unplugging your Time Machine drive. That worked for me, but now I have no backups. I'm not really sure what's worse, but this bug is REALLY annoying.

    I can't understand how this bug wasn't picked up in the testing

    Actually, I don't have a Time Machine drive, because I'm not using TM on this machine.

     

    I've got an external USB hard disk, but even if unplugged the problem remains.

    Interesting, that means this problem is much broader than we originally thought, and possibly completely unrelated to external HD's.  Keep this thread going so Apple actually does something about it!

    The problem is related to some kind of dns service.

     

    Changing a network preference can help for that session, is not needed to reboot or logout, but at the next sleep/wake up the problem will back again.

     

    I really hope that Apple will fix this: sleep is useless, atm...

    So, I made some test.... and I was wrong!

     

    With the external drive plugged in the problem occours (both ethernet and wifi).


    With the external drive unplugged everything is fine!

     

    I confirm that I'm not using TM and the last time I tested I just ejected the driver on OSX without actually unplugging the cable...

     

    Hope this helps...

    I'll be damned, ejecting my external FW800 drive and unplugging it prior to putting my iMac to sleep appears to have fixed the issue for me, too.

     

    Thanks, Slicecom & Marco.

    I'll try turning off my Time Machine (mine backs up my internal SSD to internal HDD, so I can't remove the drive) and if that fixes everyones issues we'll need to make Apple aware of this to fix it.
