Q: Lion WiFi Connection Problem

Since installing Lion on both my IMac and MacBook Pro, the WiFi cycles (wifi icon on the menu bar) - looking for network - network on - looking for network. iMac with OS 10.6 doesn't have this problem so it's not the AirPort and there was no problem prior to installing Lion.  The AirPort Utility log shows lots of connection activity but I don't know if that means anything. The network troubleshooter says theres no problem but it's causing big problems with connection speed and applications that need a constant connection are giving me network errors constantly.  Please give me some advise....

    After installing Lion, I experienced difficulties connecting to already known wifi nets.

    I tried everything I could think of, but the problem remained.

    Then I just deleted all wifi passwords from my keychain application and wifi just worked.

    Hope that helps you guys...

    Hello,

    WiFi does not work now with Lion in the iMac27 (better, it works 5-6 seconds every minute), but it works well with MBP. I don't have antivirus.

    I hope in a quick Apple release for fixing this bug!

    Ciao a tutti,

    Walter

    I`ve realy tried everything (deleting the preference-files an rebooting the machine, reseting pram and nvram, reseting the smc, reseting the wi-fi-connection etc.) in any thinkable order. It alwas helps temporarily only - the wi-fi-connection-problems always come back in my case (sometimes after some minutes - sometimes after some hours)!!!

     

    Same ISP (Germany/1&1) and router (FritzBox 7220) with an actual firmware and with the same settings as with Snow Leopard where I never had any problems...

     

    In the kernel.log it alway starts with "The BSSID changed to XXX..." and at the same time the router`s log says "The device (iMac) logged off from the WLAN..."...

     

    This MUST result from changes in the implementation of the relevant WLAN-protocols in airport!!!

     

    So there is just a small set of real options from my point of view:

     

    - going back to Snow Leopard

    - using a WLAN-USB-Stick instead of airport temporarily

    - hoping for an update

    Just thought I'd register my annoyance with LION (OSX 10.7) intermittently dropping its WIFI link. Done all the workarounds suggested by Apple and others, but its still doing it. Snow Leopard had no issues with WIFI, and all my other WIFI devices work perfectly.

     

    Please Apple, fix this issue ASAP.

    I went to network, wfi, advanced, tcp, dhcp manual and put in a fixed ip4 address, it seems to be okay for the last 20 minutes.

     

    Prior to that it was disconnecting every minute or less.

     

    Hopefully this will hold out.

     

    Btw it was doing this on snow leopard and lion, exactly the same.

    Does the problem occur if you boot into 'Safe Mode' and stay there, say for an hour or three, carrying on working as if you were booted up normally?

    How did you all INSTALL lion?

     

    Did you download it and simply click install allowing it to install over all your existing files and programs?

     

    Did you back up your system. and choose the clean install?

     

    Everyone I know who simply upgraded is having wifi issues.

     

    ALL who did a clean install forcing the system to recognize WIFI again from scratch, and reinstalling all software, are not having wifi issues.

     

    Just a thought.

     

    On an OS as bloated as Lion with so many changes to everything. a clean install is HIGHLY recommended.

    Of course I did a backup of my system. But then I didn`t do a clean installation...

    DELETE THE WIFI PASSWORD from your keychain and then re-enter it!

    When the computer restarts, hold down the 'Shift' key.  Keep holding it until the 'spinning star' or 'gearwheel' appears (you know, that clocklike spikey thing).  It will take quite a bit longer to start up, so be prepared for this. You will see a progress bar however. 

     

    Booting into Safe mode forces the Mac to do some internal house keeping, like deleting and rebuilding certain cache files and some other deep down stuff that only people like Professor Dumbledor know about. So don't panic if booting up seems to take longer.

     

    What Safe Mode also does is turn off all non - Apple extensions.  So if the Mac works properly in Safe Mode, then the problem likely rests with a Third Party extension somewhere.  You will then have to seek out the offending extension.  Search the Discussions - there is guidence on the best way to do this. 

     

    When you have found the culprit, just disable it and contact  the vendor for a Lion specific update.

    That's a point.  It would be interesting to know how much RAM and HDD space Lion demands compared with earlier version of Mac OS.  Maybe someone 'out there' can advise.

     

    But that's of purely academic interest of course, and nothing to do with this problem.
