    I've opened 2 tickets with Apple, there is no fix since the last time I opened one...about 2 months ago.

     

    It's a known issue...they have some steps you can take that may temporarily fix the issue, but not a solution that I know of

    With all due respect.... I came accross this thread by going to Apple support on line..... please, dont tell me they cant read the same threads we do? I have spoken to the good folks at the genious bar, and even had a running email dialoge with the support team.... still no fix.... Apple is known for its care, so lets see some of it....

    I have seen some online solutions saying to turn off IPV6. If you are not using Bluetoorh, turn that off also.

    What I find even more troubling, is that Lion 10.7.4 update "The latest build reportedly has no known issues"...  This basically means that Apple doesn't find this dropping wifi problem to be an issue!  Even after all the posts in this thread, and all the tickets people have taken the time to submit. 

     

    VERY disheartening!

    This is my first post. I, too, am facing this problem. When I click the wifi icon "WiFi:" constantly jumps from "Looking for Newtorks" to "On" non-stop. I don't know if it's doing it when my mouse is not hovering over it, but it would seem it is. I'm surprised Apple has not addressed this issue yet. It's very frustrating.

    I replaced my verizon wireless card and the connection for the iMac worked okay for a week.  Now same problem. MacBook, iPad, dell work wirelessly.  Not the iMac

     

    How does one flush dns settings?

    When you look at the Apple Care information, does it say, "go write something on the Forum pages and we'll count all the complaints, and then decide what to fix?"  I don't think so.  I will agree that this forum discussion has a lot of information in it.  But, these forums are for users helping each other.  If you need Apple to help you, then you really need to use Apple Care or the Genius Bar.  That is how Apple provides support.

     

    If you have been using Apple Care and the Genius Bar, then keep doing that.  I know it's tiring and I know for many, there is not an Apple Store close by.  There are so many ways that WiFi can "not work".  Apple has to understand that there is a common theme.  If you call Apple Care and it fixes the problem, but it comes back, then call them again and keep complaining.  Tell them how it is, and how its not working for you.  After 2 or 3 calls, I'd ask to speak to a manager and ask them if there is something more technical that you can do with support to track down the exact problem.  Tell them we keep patching things, but that is not working for me.

     

    I know this is all "I've already done that" kinds of stuff, but I really don't know how else to help people solve their problems.  Conversations in the forum are good for about 3 exchanges and then that's it.  So, getting a chance to work through all the issues with someone here on the forum is not happening.

    This configuration is now working for my new Verizon MIFI wifi access.   It didn't work with previous Verizon wi-fi:

    Wow, next time you can say the same thing, but in a more polite way. But no problem, I'm not posting here for your aproval.

     

    I can be ignorant like you said, but I dont have any Apple Stores near of me, and the process to open cases with apple is annoying. I live in Brazil. A lot of things here are awessome, but we don't have any Apple Stores here. The Apple is not here formally.

     

    Yesterday i had a big evolution in solving the problem, and it works until now. I've found this evidence: http://rys.pixeltards.com/2011/09/04/osx-lion-wifi.html

     

    And this video is related with it: http://www.youtube.com/watch?gl=US&v=TtxRfFAh8Pg

     

    Change the driver version worked for me, but I'm not celebrating yet. I'll wait about 5 days and I'll post the evolution here.

     

    As you can see, I'm not too Lazy neither ignorant!

    I agree with luizacc, if you have the Late 2009 iMac wi-fi problem, reverting the wirelss driver back to the Snow Leopard driver definitely works.  I've had the older driver in place for over 2 straight months now and not a single drop.  Before that it was dropping constantly, many times per day.  Certain overly cautious posters will tell you that you are in for all sorts of problems if you do this, but I havent experienced a single issue, other than the known one that AirDrop will cease to work after the driver is reverted.  I havent even needed to re-install the patch after Software Updates, so all is well.  Also, its easily reversible if you do encounter an issue.

     

    I highly recommend doing this IF you have a late 2009 iMac.  Follow the links in luizacc's post.  It takes two minutes and it works. 

     

    I expect there are a lot of other separate issues floating around this post, and this fix probably won't work for those, but for this case it definitely does work.

    I have the same problem with my late 2008 unibody Macbook. Under Lion my wifi drops out all the time! The only thing that seems to work is turning wifi off and on again. I'm not that far from the router. None of my other devices have that problem. Very frustrating.

    My Wifi problems became progressively worse with every software update. I've put up with this problem for the best part of a year. 

     

    Spent hours on the phone to Apple and Orange who provide my internet service begging for a new router.

     

    I also worked closely with Apple for several weeks who actually contacted me after I posted on this site. They fully accept the issue, they're working on a fix, but could only suggest that I change my router channel at this time as I live in a congested area. I did this and it made matters worse. I very quickly reverted back to my old channel.

     

    Although this has become a great hobby both trying to fix the problem and following this thread pressure from my wife who was never convinced when I purchased the Mac made me look elsewhere. I couldn't move to a PC as she wanted, but considered various options.

     

    I've settled on purchasing TP-Link AV200 Mini powerline adapters. My router and Mac are now connected via ethernet cables. No more problems and a much quicker speed. When you think about it upgrading to Lion has cost me hours of frustration, £58 for the adapters and I've taken a step back using ethernet, crazy. And now there's Mountain Lion on the horizon.

     

    I'll continue to follow the discussion and good luck to all you guys.

    I found a solution for this interminable headache causing glitch!!!! My issue was the same as the OP and I have even sent Diagnostic Data that Apple gathered from my computer after I called and they escalated my case to the 'Engineers'. Even after the Lion 'updates' the issue persisted.

     

    If you have been plagued by this same issue try the fix by following the link. Like the guy says in his post, make sure your computer has the Atheros WiFi Hardware to  begin with. My iMac has Atheros and this very easy solution did the job! No drops or issues since the patch.

     

    This is literally the only solution I was able to find after a cumulative 24 hour, or so, search for a solution! Read the guys post as it is very informative on the matter.

    I have seen several suggestions to revert back to a Snow Leopard driver to solve the wifi dropping issues.  HOWEVER, I have a Broadcom wireless card in my MBP, NOT Atheros.  Is it still possible to revert to the older Snow Leopard drivers with the Broadcom card?  If so, does anyone have instructions?

    I didn't read through this entire thread, so forgive me if this has been mentioned before:

     

    I've made a very interesting discovery this morning while troubleshooting this issue. I was testing ping response times of a 2011 MacBook Air that came with Lion pre-installed from my workstation. The ping response times were all over the place, anywhere from 20-200 ms! I have been trying all of the different suggestions that people have provided and checking the ping times. No change. I said to myself, I might as well run Software Update to make sure I have everything, and sure enough when I fired up Software Update on my MBA, the ping response times dropped down instantly to >1 ms. I was thinking to myself, what did I do differently? I couldn't think of anything except for SWUD, so I stopped it, and immediately my ping reponses went back up and where all over the place. I resumed SWUD and they dropped back down. Freaking bizzarre I know!!! I have also tested it with simply pinging an apple site (swcdn.apple.com, support.apple.com) from the client and that seems to help as well. I've heard of people suggesting pinging facebook.com or google, but that didn't work for me, only the apple sites did.

     

    I will continue testing today and keep an eye on things, but I just wanted to share with you all!
