    The only "workaround" I'm aware of is to reinstall Snow until a fix is released.

  • Topher Kessler Level 6 Level 6

    Are you able to enable WiFi if you boot to Safe Mode (some systems will not be able to do this, but some should).

    David, do you have a recent time machine backup? If so, rollback to Snow Leopard that is the only way to fix this for now. Attach your time machine drive to your mac, reboot it and hold CMD + R during startup. From that point you will see what you have to do next.

     

    Would you please be so kind to post your firmware version under Snow Leopard and/or Lion? Thx!

  • davidnowhere Level 1 Level 1

    Yeah i just backedup before installing lion...thanks!

     

    I'll post the firmware once i get home tonite. Thanks guys!

    Just tried to boot in safe mode (by holding shift during boot, right?) same problem. Also tried verbose mode and it does show the airport card. Really think this is a firmware issue

  • davidnowhere Level 1 Level 1

    hey guys. Weirdest thing. Just got home n wifi is now working fine at home. So no problems now....

  • crye55 Level 1 Level 1

    So you just tried to turn it on and it actually turned on? Did you do anything?

     

    Still dead for me, on with Applecare now.

  • dongsheng Level 1 Level 1

    I got the exactly same  problem, looks like the firmware needs upgrade!

  • dongsheng Level 1 Level 1

    Hey guys, I fixed this issue by turning mac off/on again, note, I took the battery out to release electricity, it worked now!

  • kevinrobers Level 1 Level 1

    Already tried that with no succes but thx!

  • kevinrobers Level 1 Level 1

    I'm currently trying to find out if this problem also exists on the developer previews of Lion. I've just tested DP4 (the last version before the Golden Master and final release) and it has the same issue. But. It has another firmware version.

     

    Lion Golden Master / final:

    Software versions:

         CoreWLAN 2.0 (200.46)

         CoreWLANKit 1.0 (100.43)

         Menu Extra 7.0 (700.42)

         Config plug-in 7.0 (700.57)

         System profiler 7.0 (700.3)

         IO80211 Family 4.0 (400.40)

         WiFi Diagnostics 1.0 (100.26)

         Airport Utility 5.5.3 (553.20)

    Interfaces

         Card Type: Airport Extreme (0x14E4, 0x8D)

         Firmware version: Broadcom BCM43xx 1.0 (5.100.98.75.6)

     

    Lion Developers Preview 4

    Software versions:

         CoreWLAN 2.0 (200.44)

         CoreWLANKit 1.0 (100.42)

         Menu Extra 7.0 (700.41)

         Config plug-in 7.0 (700.51)

         System profiler 7.0 (700.3)

         IO80211 Family 4.0 (400.35)

         WiFi Diagnostics 1.0 (100.26)

         Airport Utility 5.5.3 (553.20)

    Interfaces

         Card Type: Airport Extreme (0x14E4, 0x8D)

         Firmware version: Broadcom BCM43xx 1.0 (5.100.98.69.6)

     

    I'm currently looking for older developer previews.. but.. well... they are not really easy to find for the obvious reasons

  • galmeida_ Level 1 Level 1

    I had the same problem, the solution was resetting SMC: http://support.apple.com/kb/HT3964

  • galileo1 Level 1 Level 1

    I can confirm that taking the battery out and resetting the SMC worked for me as well. I'm pretty sure I did this last night, but perhaps I didn't do it correctly.

     

    Thanks.

  • jdcliff Level 1 Level 1

    I've got the exact same issue! 

     

      Card Type:          AirPort Extreme  (0x14E4, 0x8D)

      Firmware Version:          Broadcom BCM43xx 1.0 (5.100.98.75.6)

     

    I've got a late 2010 MBP running Lion and it works perfectly (of course it has different airport card and firmware.  The 2008 MB is a no-go.

  • kevinrobers Level 1 Level 1

    Ok, this is REALLY strange... Because people were reporting that resetting SMC worked i've tried it again and wifi seems to be working... I'm REALLY sure i've done this before and done it correctly... The difference was that i had Lion DP4 on a external drive while i was working in SL and then did the SMC reset... After the reset i've booted DP4 and wifi was working... After that i've upgraded SL to Lion through the App Store and now it's working... I'm keeping you guys posted!
