    Hi all I have your same problem...

    I have tried these solution:


    • reset Safari
    • disabled all safari plugins
    • change Wifi channel
    • IPv6 "Only local link"
    • Reset SMC controller
    • deleted preferences.plist
    • deleted SystemConfiguration folder


    Today my connection seems to be stable even if a couple of times (in 1-2 hours) It falls asleep for 20-30s/1min...

    I don't know what thinking about...I'm waiting for an answer from Apple.

    Sorry my poor english i hope to be clear.

    Lion and Airport 7.5.2 Firmware - Do not upgrade. 


    I have now upgraded my third airport express, and Time Capsule.   Now all 3 have connection issues.   I left one with older firmware as a backup and now that I've updgraded it, it too now screwes up connections.

    My wifi connection finally stabilised after I changed the modem channel to 11.

    Absolutely no problems with Lion and AirPort Firmware 7.5.2, and hundreds of Apple Stores across the USA have no problems with their demo machines running Lion and the in-store base stations running 7.5.2.


    The root cause lies elsewhere, it's not due to an interaction between these two.

    My problem only occurs when I have a cd or DVD in the MBP, or a hard drive attached.  Its a perfectly repeatably event.  If the MBP is connected to one of these the internet does not work (except for cycling wifi off/ on).  Disconnect the CD/DVD or drive....and it works fine.   Usually those demo MBP's in the Apple stores do not have any connected devices like that ....right?

    Do you tink Tenortim has identified the problem in this thread? I see it is being continued to cover Lion too.

    That's wonderful I like to play with all the demo units in the store.  Unfortunately me and many others don't live and work there. 


    Anything that received a software update has failed. 


    You name it, I have it. Everything apple.  I'm a heavy user with lots of experience. There is a connection because after updating devices to 7.5.2 and or Lion it shows up.  I've kept one at version 6.3 and its fine. No connection issues.    Same airport express, same settings just the firmware change. Its a backup so I can swap out equipment if it fails. 


    I'm sure apple knows about it and some update will follow. Just have to let them know. Enough people talk about it,  the media end up reporting on it and that sometimes give them the kick they need to acknowledge and fix it.  If I was Apple I would not want to admit an issue either.

    Also countless computer hanging when started from sleep not being able to connect to wifi.  Have to turn wifi off and back on again SOMETIMES helps. This is a LION issue.  It should not hang and freeze. 


    The connection issue is another.  New system, new bugs.  Most business wait until second and third updates before upgrading but some of us trust Apple too much and just jump on it the second it comes out. Fine for the average user, not fine for business.  Now with 10% or more using Apple for business, its time to pay attention.

    So far we have people who have apparently solved their problems by some abstruse fix, others who cannot fix them whatever they do.  We have people who have a problem with a particular pairing (such as Lion and AirPort Fiirmware) and others for whom that same pairing works fine.  There has been talk of using channel 11 on the router.  That works for some but not for me.


    All we can say for sure is that there seems to be no One Size Fits All solution and no clear idientification even of the area where the problem may lie.  We are approaching 500 posts in this one thread alone and nearly 37,000 viewings.  We must assume that a significant number of those 37,000 have also had problems which they have either solved or who cannot be bothered to post about it.


    Of course we each of us have different hardware and software setups and that kind of a thing is a real nightmare for the likes of Apple.  But isn't it part of their job description to take that into account, in much the same way as a car designer has to accommodate all likely surfaces their cars might travel on?  Am I being too demanding?

    My experience is the same. Late 2009 iMac i7 with an Atheros card, constant problems after the Lion upgrade. But my MBA and Mini with Broadcom chipsets have no issues.

  • edward70 Level 1 Level 1

    My Lion wi-fi problem is very similar and the same on all three machines.  Internet connectivity stops unexpectedly. Usually 3-4 times in a day. 


    The (temporary) cure is to open Network Preferences and then "assist me"

    After that I click diagnostics. 


    In the Network Status bar on the left the patter is always the same.  Wi-fi through Network settings is a green light, but ISP and Internet are red. 


    Then, the machine does its process and magically the internet connectivity is restored, but never permanently. 


    Apple, please fix this.  I never had this problem with prior OS X versions.  Clearly a glitch that needs to be fixed in an update.

    FYI.... I filed a bug report in the developer area that one of the posters here recommended.

    Typically the Wifi connection drops whenever the iMac goes sleep and wakes up.


    I think it's got something to do with the power management.

    Do you use other wireless devices such as wireless telephone?

  • matfromchicago Level 1 Level 1

    Does anybody has my problem at all?


    I cannot connect to the wireless router. Connection Timeout occured.
