    I've had 10.7.1 running for around 24 hours now and unlike the previous 24 hours on 10.7.0 I've had no issues at.

     

    Everything appears to be back working as it should do.

     

    iMac 21.5-inch, Late 2009, 3.06GHz Intel Core 2 Duo

    After 10.7.1 update, reset PRAM of your Mac can really fix the "no wifi after wake up from sleep" issue. I have done this and test it thoroughly, so far so good. Opened the lid of my MBA and it connects to wi-fi 3-4 secs, can surf web, Adium auto connect itself to internet. This was a 5 mins sleep test. Then I close the lid of my MBA to let it sleep for an hour. After coming back from dinner, I opened the lid and the wifi comes back. So guys don't give up yet, please reset the PRAM if you still have no wifi after wake up from sleep.

     

    I am going to perform such test continuously for this week and check.

    I'll give that a try. I did notice that I can not even see my Airport Extreme at all when booted into 10.7.1. I can see it when booted into 10.6.8 though. And I can see it from a Windows 7 laptop too, so the Airport Extreme is fine.

     

    I'll try resetting the PRAM and deleting some Airport preference files too.

     

    I realize I could Erase and re-install and then add my files back in from my time machine backup or one of my other backups, but I would really like to figure this out.

    Sadly 10.7.1 has made no change. I thought at first it had but the problems I had before are all there:

     

    1.     It keeps gping to sleep and waking up immedaiately if there is a network drive plugged in.

     

    2.     If I put power to Time Capsule it knocks out my Airport Extreme and WiFi. (Lion will not/cannot configure Time Capsule either.

     

    3.     iCalc does not sync.

     

    I also found after installing 10.7.1 that it made iPhoto inoperable. I had to delete it, reinstall it from the iLife disc and then check for software updates for it - I knew there was one but this time round there were 2, it loaded the first and when I ran it it said it eneded another.

     

    Everything else works OK, it all did before Lion, but Lion 10.7.1. still does not like external hard drives connected to the network.

     

    I did reset the PRAM etc.

    PRAM reset did the trick for me. 

     

    Previously I could reproduce the problem by closing the lid of my MacBook whilst it was doing a Time Machine backup.  I've tried 3 times now and I've not been able to reproduce. 

     

    Looking good!  Thanks @Lomen

  • ctomer Level 1 Level 1 (35 points)

    Despite my initial optimism after the PRAM, I was able to reproduce the problem today

     

    Anyone tried creating a fresh account?  I'm wondering if there's something in my Library folder that causing this.

  • JimHughes Level 1 Level 1 (0 points)

    I finally gave up and did a fresh install of lion from a USB boot disk I made then I transferred my settings over from my Snow Leopard backup disk.

    Everything is working again.

    I wanted to figure it out but it was getting too annoying.

    So for me everything is working again.

    Ok so... I can safely say 10.7.1 has certainly not fixed my problem.

     

    My wake from sleep network issue only ever occurs when I have a drive mounted, be it time machine or what not.

     

    Just lifted the lid on my MBP and saw the time machine volume was mounted, it wasn't even in the middle of a backup or anything it was simply just left on the desktop as a mounted drive and once again my wifi would not connect and I had to manually disable the wifi and re-enable it which takes forever when the MBP is in this state.

     

    Need a fix please Apple - and soon!

  • richardfromdurham Level 1 Level 1 (5 points)

    This was the same as my problem, a mounted USB drive and the iMac would go to sleep and switch back on again. Time Capsule presented a different problem. After installing the upgrade the going to sleep problem seems to have abated, am not convinced it has gone completely and need to spend some time observing the iMac.

     

    The Time Capsule used to knock out my WiFi and Lion would not recognise the Time Capsule. A hard rest of the Time Capsule (pressing in the reset button on the back) cured it but not initially. I had to do it three times before it worked OK. Time Capsule no longer knocks out the WiFi and Time Machine runs fine.

     

    Assuming the going to sleep problem may have been resolved the only other one where I assume yet a further updgrade from Apple is needed, is to get iCal to sync - this problem is covered in another part of the forum.

    Exactly the same problem here too. Disonnecting Time Machine made no difference to me either. Nothing shows up in diagnostics. Only workaround is toggling wifi on and off.

    I thought 10.7.1 fixed this problem for me, but it still occurs, just not every time like it used to. It happens about 10% of the time now. This is ridiculous. FIX THIS APPLE!

  • Sarah Level 3 Level 3 (795 points)

    Ah no, I came on here to say that it had fixed it but it looks like it just makes it an occasional problem instead of a constant one. Boo

  • JimHughes Level 1 Level 1 (0 points)

    I thought the problem was gone too, especially after a clean install, but no it has happened once since the 10.7 install, I have upgraded to 10.7.1 since the clean install. So I guess, like you, it is happening less but it does still occur.

    In all seriousness, have you contacted AppleCare so they know your particular configuration details and can try and reproduce your precise issue?

     

    Apple's engineers are very good, but they're not psychic, and if you're still having issues they need to know that; it's very likely they are troubleshooting what configurations they can.

    I'll second William Kucharski's suggestion. Remember, the purchase of Lion comes with 90 days of free telephone support, so you won't have to pay for the call.
