    Ok.. as a suspected..  no reply on pings from airport extreme nor google server.  After joining network again..  pings are sucessfull.

    Do you know about the airport utilty?  The following command will put a symlink into /usr/sbin, so that you can run it from "terminal" more readily.

     

    sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport

     

    You might try running airport -s and airport -I while your mac is trying to connect, and if it stays connected long enough, to see what is visible to the network card regarding the outside environment.

     

    The other thing that you might do, is turn on the debugging/logging for wifi as described here.

     

    <http://prowiki.isc.upenn.edu/wiki/Enabling_Advanced_Logging_for_Wireless_in_Mac_ OS_X>

     

    to see if there is anything that you can discover about what the "WiFi" driver is reporting as the connection loss reason.

     

    Some people have turned on logging and then stopped having problems.  That can suggest that there could be a small "timing" issue which is avoided when the software has to spend the time to log data as it goes along.

    Dear friends from 161 pages of support discussions: Lion 10.7.5 is out, support page says ao.

    This update also includes fixes that:

    • Resolve an issue in which icons in Launchpad could get rearranged after a restart
    • Improve Wi-Fi reliability for iMac (Late 2009 and newer)
    • ...

    If you still have Lion, please update and check whether your connection is improved. I will test your morning and report.

     

    I had issues with an AVM Fritz!Box 7390 on all bands, and never on my TC on 5 GHz exclusive. Good luck all.

    @jeroen184

    Your suggestion to solving issues under Lion - which is bought and paid for, is to update to ML - which must be bought and paid for. 

     

     

    Would you ever considering purchasing any other device, take it home power it on, find it faulty og missing some key features. Then return to the shop and pick up another one - on your own cost - to solve the issues the first unit have.

     

    Not to offend you as your giving the best advise at your disposal, but that is ******** - I Blame Apple!.

    @Vognbygger

    I am sorry if I gave the impression that upgrading to ML would be a solution. I think I read it's not.

     

    I am still on Lion (out of the box with iMac 2011) and yesterday EU evening an update 10.7.5 to Lion became available, which includes the said "Improve Wi-Fi reliability for iMac (Late 2009 and newer)" improvement. I will remain on Lion and hope and pray my Wi-Fi issue is now resolved. The issue was still present when connecting to the ISP's base station FritzBox; I bought the TC for backup purposes in the first place, and as a resolution am now using it as my WiFi base station, without a single issue.

     

    I am fully with you that you should not buy an Apple basestation to resolve this issue.  The issue is Apple, they should solve it.

    My mistake!

     

    for an update on my issues with Lion, i can say that i almost cleared my issues, almost. It connects, automatic and all. but it takes some time. And it continiously create new wifi - networks, relating to the same wifi network. So my wifi list on the macbook gets packed with <name of wifi> 1,  <name of wifi> 2,  <name of wifi> 3 and so on. annoying but it works.
    Issues exits only on PSK password protected networks, unprotected networks work like a charm. No future there.

    bratman91's solution of changing the MTU to 1450 immediately fixed the problem that had plaguing my iMac and laptop all day.

  • 2,406. Re: Lion WiFi Connection Problem

    I can claim no intellectual rights for the MTU solution - changing the MTU was not "my" solution and was suggested in a variety of forums. My post was to record for the possible benefit of others that it had workd for me when all other potential solutions had failed. As a follow-up, however, a software update a couple of days ago addressed the wifi issue and, in order to test its efficacy, I set my MTU back to its original figure of 1500. So far, after almost 48 hours, the wifi connection has been stable so it looks like Apple has provided a proper fix for the problem. It will be interesting to see how it stands the test of time.

    Can anyone else confirm that Apple's latest Lion update has solved the wifi issue? Would be great if it were the case!

     

    I deinstalled Lion to Leopard a while back ago because I just couldn't find a proper solution, but I would be extremely happy to be back up to date...

    I cannot answer your question a I do not have the problem, but you may be interested in the new network diagnostics tools in Mountain Lion.

    Interestingly, my wifi connection problem only started AFTER the Lion update on Wednesday, so I'll stick with this remedy for now.

    jeroen184 Level 1 Level 1 (0 points)

    @OuweEgberts, the 10.7.5 update did not resolve my issue with an 2011 iMac and an AVM Fritz!Box 7390. Changing the MTU from 1260 to 1500 also did not resolve anything. Alas, not for me.

     

    Anyone else got better news?

    10.7.5 fixed my issue just for 2 days. After 2 days without any changes made to the system I'm back to my original issue: doesn't connect automatically even though the network appears there.

     

    This is a shi* situation, I have used Windows, Sabayon, Ubuntu, Debian and other Linux flavours and I never had such a problem. Considering it's using their own machine, Apple should be ashame of this. What if I will be using OS X on a computer not build by Apple? I'm wondering if would ever start their "shining" operating system.

     

    Maybe instead of focusing on things like Facebook connect, and other fancy things like that, should focus on some real problems. And give to us an OS which really works, this is just what I want, to work, I don't ask for any extra features.

     

    Where is the justification for those big extra money you pay when you buy an Apple product??? Where is the support? Here? Between us? This must be a joke.

     

    I hope someone from Apple reads our emails and this forum since I'm very dissapointed with Apple, I will never buy any of their products ever again.

    Blasphemy!  Apple would never create anything that wasn't perfect.  Fanboys everywhere will be up in arms about your blatant lies!  All seriousness aside, their inability to resolve these issues that thousands of people have been having is a little absurd.  It's not like this is the first mass issue that they've neglected to resolve.  If people can use an USB dongle and the problem is resolved then obviously it has something to do with the built-in wifi and it's drivers.  I ran into a similar problem where a lot of iMacs with a certain video adapter were randomly locking up after a certain update in snow leopard because of a driver update and it was never fixed in any of the other updates.  The only solution was to manually revert it to the old drivers and any subsequent updates that you install that update the drivers would break it again and require re-installing the old drivers.  The point is they just don't care as long as they're still selling new systems and the goal is to push you to buy new hardware whether it be a new system or router.  Fix your products Apple or your customer base will become even smaller then it already is.  Apple products are supposed to "Just work!"  They're supposed to be user friendly and easy to use.  It shouldn't require people to have unix/linux knowledge to fix issues that shouldn't be there to begin with.  "Technicians" saying that it's your router or anything other then their own product are lying especially when people running boot camp on the same system have absolutely no issues with their wifi under windows 7.  So...I don't blame you for saying you won't purchase another Apple product.

    Have you had a chance to run any of the diagnostics mentioned here or other threads, to see if it might reveal something that you could change to work around or fix the problem?

     

    If your WiFi connection is showing "connected", but safari is saying "you are not connected to the internet", it sounds like an argument with DNS services between your computer and your ISP.  If you look at System Preferences->Networking->WiFi->Advanced->DNS, what is shown there?  If you add 8.8.8.8 (the google DNS server), does anything change?

    I have loaded 10.7.5 and still no good. Used 8.8.8.8 and almost anything else anyone suggested and still my wiFi shows connection but no internet connection. I have to turn my WiFi off and on and then it works for a short while. This is driving me crazy
