    I have a big trouble trying to connect to any wifi network with my new MBP 2011 model. Especially, I get a very weak signal with my home wifi router when every other device in my house has no problem at all. At the same place in my office where I get a 5/5 signal with my windows 7 laptop and connect without a problem, my MBP gets half the signal or less and drops the connection almost every 30-60 seconds. Also the connection is very slow. I have updated the router, set it only in g-mode, used wpa2 or no encryption at all, flashed the PRAM etc etc. No solution till now. I have also pinged my router and the packages where dropping one after the other.

    And to be honest even if I ever manage to fix the problem for my router, how I'm supposed to connect anywhere else where I don't have access to the router settings ? Such us my college wifi or other public stations.

    Please Apple, find a solution soon or I'll have to return the laptop immediately.

    Add me to the list. During browsing, connection will drop, especially when download files. This should not be happening; my tiny little netbook does not have the same problem, downloads and surfs faster than my MBP 2011 on the same network. Please fix this aggravating problem.

    I have completely same issue. There is no clue so far. There are many people who are experiencing same issue in Japan. One of them is getting hardware replacement, let's see how it goes. I believe that this must be firmware issue...

    Please log you issue with Apple support. This is the only way you can be "added to the list" and contribute to a solution. This forum is not an official list of anything, rather a community discussion. Thanks.

    With no doubt, That's a defect with my WIFI/Airport experience with 2011 MBP to me. I was wondering what can I do except posting here or even raising this issue to genius bar ? I meant from what I realized everything I can do now is "WAIT", what if Apple won't release a fix in ONE-YEAR(warranty period)? does that mean I have to live with this defect from whenever warranty expired without even complain it to Apple? what can we do now?! This issue is really bothering!

    Add me to the list of people experiencing this problem. However, two noteworthy observations based on extensive troubleshooting:

    -The same problem arises when disabling the AirPort card and using a USB adapter with its own software/driver, although it is not nearly as severe. Where the AirPort will lose its internet connection (but NOT network connection) every 5-15 minutes, the USB may lose its internet connection every 30-45 minutes.

    -It is not router dependent, and other computers connect and maintain internet connectivity with all tested routers without any issue.

    -The AirPort card works, CONSISTENTLY, all day long if I boot into Windows 7 via Bootcamp

    These points make me believe the problem is OS X. If I keep my MBP long enough, it will be interesting to see if an upgrade to the new version eliminates this problem.

    I bought a brand new Linksys E3000 as I thought it was an issue with my aging Netgear router...it turns out to be an Apple issue all along...what waste of time and money that turned out to be.

    This is my second MacBook Pro (I had the mid 2010 model for two weeks before upgrading to the 2011 model) and I've been very happy with everything else until this same issue plagues my 1 month old MacBook.

    dusktilldawn,
    I have a E3000 and it seems to work perfectly fine for me. What is the exact issue you are seeing and when you say your wireless drop's, does the AirPort Menu Extra still stay dark ? or does it go grey ?

    I have the same problem, just bought a new MBP 15" delivered last week. My connection keeps showing "connection timeout", where all my other devices, older MBP 17", ipad, iphone all stay connected. I am using the AirportExtreme for many years already, never had any of this timeout issue. Went to a friend place and also got the same connection timeout after a while. i hope this can be solved soonest, as i find it very inconvenient and also reflect the quality of this product.
    Hope this feedback can support your discussion with their engineers.
    Thanks.

    I hope it is, although I guess most of us will have at worst 12mths warranty. My new MB went back last week. 15" i7 2.2ghz. After trying numerous wireless workouts as mine was fine with a strong connection 5ft away, however the further I moved away the worse it was. Unable to connect at all 15 - 20 ft away. On the system network utilities it showed 90% packet loss after pinging google. Apple then asked me to boot from the instal disk, network utility from the disk menu and I was able to connect with zero packet loss. Connection was excellent. Apple then said that this is a hardware issue and being that the MB was 3 days old they would replace it or cash back! Don't want the bloody cash as this it the best rated laptop for my work.

    Getting the new one in a couple of days time so I will definitely post how the new MB responds. I must say that Apple has done everything possible as far as customer service letting me know every detail of the new MB progress. I did look at ASUS but the MB is so good. I know many of us forked out nearly 3k! Frustrated, 'yes' But hold on will be a fix soon enough, Apple don't stuff around.

    Just been told by the apple genius bar in London that apple do not have this listed as an issue or known fault - I can leave my machine with them for a stress test that could take up to seven days, or call teh inline store where I bought it......

    I also have issues with my Airport card; I bought the latest generation AirPort Extreme and MacBook Pro, and I am having issues with latency and (occasionally) throughput. Latency is consistently above 100ms (as opposed to a Windows laptop with sub 25ms sitting next to me); both connected to the Airport Extreme.

    Throughput on the Mac also varies wildly, with random connection issues and drop outs. A 60GB file takes approximately 3 hours to copy over Wi-Fi on the Mac with speeds dropping to 0 on several occasions, a peak of 11.2mb/s; but an average of 3mb/s.

    The Windows laptop takes about 2 hours to do the same transfer of Wi-Fi, constant speed throughout.

    I have a 2010 MBP that recently experienced some of the problems that I am reading about in this thread. The wireless connection would drop even though the airport icon in the menu bar would show full strength. By trial and error I found it easiest to keep the system prefs open to network and turn airport off and then on to reset and connect. I contacted AT&T and after 40 minutes on the phone, the tech told me to keep changing the wireless channel number until the problem cleared up.

    Long story short, that didn't work. But, while reading the threads, I happened across something that I thought I'd try. My wireless authentication security was set to WPA2-PSK. I changed it to WPA-PSK and it has been working without a problem.

    The second plus side to this has been my iPhone which seemed to have all the same wireless problems and now no longer drops the connection.

    I don't know why this worked or if it will work for everyone. But this one change has worked and taken a lot of stress off of me.

    Hi all!

    Did anyone try to downgrade the firmware? I dont know if its possible or not, but somebody posted that older firmware works well with the same card. Maybe its worth a try

    I couldn't find a method to downgrade the firmware, but I tried to use the IO80211Family.kext from my old macbook pro and while it didn't complain on loading, the Airport didn't initialize at all. The kext from my old macbook pro is version 314.? while the one on my new macbook pro is 320.1, which I thought was weird because both are running 10.6.7.
