    does the computer from which you copy the plist files have to have the same airport card and firmware? or does that not matter?

  • jacen2141 Level 1 Level 1 (0 points)

    That doesn't seem to matter. The files I used came from a 2010 MacBook Pro.

  • kevinrobers Level 1 Level 1 (10 points)

    The files i used came from the latest Macbook Pro so i think it doesn't matter but didn't check the airport card and firmware versions

    I too am having problems with wifi connections after upgrade to Lion from Snow Leopard on my IMac. Repeated turning wifi on and off eventually accomplishes the connection. If I walk away and the computer goes to standby, I loose the connection again.  So annoying that I'm considering reinstalling Snow Leopard that was working just fine. This many people having issues and no response from Apple. What's up with that.

    Hmm sounds like a different problem to me. What exactly did you try? Does your ethernet connection work?

     

    @peterfromwallingford Apple is working on it. Some of us are in contact with an Apple engineer that is looking into it but it takes some time

  • Dchilders001 Level 1 Level 1 (0 points)

    Ethernet works fine.  I've been reading the thread and am waiting on Apple, just wanted to add my specs in case they would help.

  • jacen2141 Level 1 Level 1 (0 points)

    Any word from anyone?  I haven't heard back from my support engineer in several days. 

  • logix812 Level 1 Level 1 (0 points)

    I am having the same issue.  If I turn my wifi off and then attempt to turn it back on, it will not turn on. I have to reboot the computer to get it back.

     

    I'm running a Early 2008 MBP 17" 2.5ghz Core 2 Duo under Lion (11A511)

    I have this same config and I have the same issue.... it actually started back in Snow Leopard, which I believe is different then many people here have reported. It's the reason I upgraded to Lion in hopes of getting my wifi back. It got to the point where I reboot would "fix" the issue but it never lasted long. Sometimes minutes, sometimes a day.

     

    With Lion Ihad wireless support for a few days, even after sleeping the system. Now it is dead. A reboot seems to have no impact. Just an empty pie slice up by my clock... I want my pie back.

     

    I think if you do some digging you will actually see this has been an issue for Apple for quit some time. not just with Lion. I'm rather disappointed Apple has let it go on this long. It's been nearly a year for me. It was nice to see people posting interactions they had with Apple engineers but that seems to have gone cold now.

     

    Here's my specs:

     

    Software Versions:

      CoreWLAN:    2.0 (200.46)

    I have the exact same issue. WiFi won't turn on on my Late 2008 Macbook Pro after upgrading to Lion and restarting.

     

    Still no fix for this?

     

    Thanks

  • kevinrobers Level 1 Level 1 (10 points)

    The temporary fix is to get the content from the /library/preferences/SystemPreferences folder of a working mac and replace your own files and reboot. This works until your next reboot. Is anybody still in contact with Apple?
