    "And the "problem" isn't much of a problem.  You just have to select the Wi-Fi network.  That takes, what, 1/2 second?"


    I'm not sure that's a good enough answer based on an expensive machine for a company who should be able to nail the fundenmentals. The frustration when you know it's dropped again can't be covered by the fact it takes a second or not

    "And the "problem" isn't much of a problem.  You just have to select the Wi-Fi network.  That takes, what, 1/2 second?"


    The problem is that I have to reboot my router and computer 10x a day. I think you have missed the point of this 90-ish page long thread.

  • Sammy_Sam Level 1 Level 1

    If we buy a device that is so much more expensive than your average machine, there is no reason to have to keep rebooting.   If you do, something is wrong.  As I previously mentioned, this has to do with their update.  Reinstall lion and DO NOT update firmware, airport utility, and operating system.  It will then work although we should be able to update and not have this problem.  Apple is not listening to us and makes me

    Think they don't care.  Also, the genius bar are a bach of people who are guessing.  They don't know anything.   When you calm apple they act as if they are not aware of the problem.  Let's all call for a week straight and maybe they will start to listen. 

  • greenkie Level 1 Level 1

    Yeah, as I said on the previous page: I have snow leopard, and it's been a problem since the day I took it home from the store (Jan 2011). Not just a lion issue.

  • mapar70 Level 1 Level 1

    An interesting troubleshooting step would be if someone who is currently experiencing the problem installed linux instead of mac os, and see if you still experience drop-outs. If so, then it's the hardware. If not, then it's mac os.

    @jamied1901 and @greenkie -


    I agree that this is an issue.  And (not to defend Apple), they can't test every permutation of MBP and wireless router.  With that said, I saw the problem with my D-Link DIR-655 Rev. B, firmware 2.03NA.  I see *less* of a problem (1) with firmware 2.01NA, and (2) when my MBP is plugged in.


    If it is hardware related, Apple should verify whether the new "3X3" wireless implementation is flawed.  From Anandtech ( ings-sandy-bridge/11):


    - 2010 MacBook Pro included 802.11a/b/g/n support using a BCM4322 which included full 2x2 MIMO support, meaning two spatial streams were supported. Bluetooth 3.0 was provided by a BCM2070, and the whole solution was simply a BCM954224HMB reference design


    - Inside the 2011 MacBook Pro is a BCM4331 and three clearly U.FL antenna connectors (on the left) for WiFi, as opposed to two in the previous design. The 2011 MacBook Pro refresh is the first line of Apple products to bring 3x3 radios that can finally enable faster transfer rates and better performance at the edge of WiFi range.

    Very important information for those who have persistent wifi issues and an upgraded SSD drive.


    I have a summer 2011 MacBook Pro which has had wifi issues from the beginning - and it is all my very own fault as I installed an aftermarket SSD drive (Samsung 830 series, highly recommended for speed and reliability) and enable TRIM using an application called Trim Enabler which I do not recommend.


    As you can read over here the application replaced kernel extensions with older versions, causing OSX to drop wifi and shut down slowly.


    Trim can be enabled quite easily using the terminal commands on the above mentioned website.


    One unresolved issue, for me, is how needed Trim is on modern SSD drives which have onboard garbage collection - any experts here?

  • zoelbarker Level 1 Level 1

    My WiFi drops out every time I use my Macbook Pro. I spend most of the day searching for network/joining network/entering password - on average about 20-30 times a day. I only have one WiFi network and it works fine with the other two macs in my house (iMac & Macbook).


    Until now I thought I had spent £1700+ on a duff Macbook Pro, my old one lasted 5years with few issues. My new one, bought in Nov 2010 has already been replaced once due to hardware issues and I am so fed up of trying the troubleshooting, temporary fixes for this WiFi issue.


    I am a designer, WiFi is essential to my work but I admit, when it comes to all the firmware/kernel extensions etc mentioned above that it just sounds like hard work and gobbledy gook to me. I still have NO idea what I should do to make my working life easier and to be honest I shouldn't have to know, I invested in this product in good faith because it should make working more efficient.


    Apple, please stop me from resenting spending SO much money on a Macbook Pro. This is just not on, I invested so much money in a product that was supposed to make my work life more efficient and it is doing quite the opposite and adding stress in the process.


    Is Apple going to provide a solution to this problem or replace these dodgy products with replacements that work???????????


    Distressed, annoyed, resentful.

  • donstenk Level 1 Level 1

    My gobledegook is only applicable to those who replaced their hard drive themselves with a Solid State Drive (a fast drive like those in MB Air).


    Those who did so, and enabled trim, can resolve the problem by disabling trim or reinstalling OSX.

  • zoelbarker Level 1 Level 1

    Sorry - by no means meant your words were gobledegook - I was referring to my brain - I think it's great that there are so many people offering technical help. I hope Apple can shed some light at the Genius bar as it's my only option - I very much doubt it though!

  • Boscoh Level 1 Level 1

    This happened on my last Leopard MBP and is now happening on my new Lion MBP. Doesn't happen when I boot into Windows, only in OSX. It's got to be some sort of software issue.


    I'm connecting using WPA2 to a Cisco 1252. Logs on the Cisco show "authentication failed" and logs on the MBP show "previous authentication no longer valid".


    My wife has a Windows laptop and she never has issues.


    For lindros2, don't be so dense. It's a huge problem. When you're VPN'd into work, using a VDI client and you get dropped, then have to spend several minutes reconnecting to VPN and waiting for your virtual desktop to load again - 10 times a day, it's a problem. When you're uploading a 2gb file to an FTP server and your wireless drops, and the server doesn't support resuming uploads, it's a problem. When you're on a web meeting with a customer and the wireless drops and it takes you 1 to 2 minutes to get back into the meeting, it's a problem. When you're serving movies from your laptop and the wireless drops so often that your family gets frustrated and doesn't want to watch anymore, it's a problem. When you expect to be able to use the MBP as a powerful business and multimedia tool, but can't, it's a problem.


    At this point, I'm about to go back to Windows. For all it's shortcomings, at the least the wireless never did this on any Windows laptop I've owned over the last 10 years.

  • iTMR Level 1 Level 1

    Thought it was just me.  Umpteen times over the past several months had FrontierCommunications troubleshoot constant dropped WLAN and the need to run diagnostic to reconnect.  Yes, it is a problem!  Only solution for constant dropped wifi is for one to hover over a narrow countertop tethered to router using ethernet cable in order to work uninterrupted.  Not what I pay for or how service is set up through my provider -- not at all what I paid Apple for this top of the line wifi capable MacBookPro purhased less than a year and a half ago. To review these 90 pages of posts which date back this issue as a known issue well before my and most of these purchases above were made, I am appalled Apple has not addressed a fix of this for its customers and find it reprehensible Apple continues to ignore it.

  • ElenaTheNerd Level 1 Level 1

    I think I may have found the solution. 


    After months of losing connectivity, the problem has seemed to be resolved. I have spent way too much time trying to resolve the probelm and Apple has been absolutely no help.  I found this website that outlines the steps to fixing the problem.  I hope others find this a useful as I did.




    In case the webpage goes offline, here are the steps:

    • click on the Apple Menu () on the upper left-hand corner of the screen
    • select System Preferences
    • click on the Network icon
    • in the dialog box, click on the Advanced tab in the lower right-hand corner
    • click on my network entry and drag it to the top, so that it was the first entry in the list
    • click on Apply Now and shut down your computer.
    • re-start your computer and zap the PRAM. (simply hold down the Command (⌘), Option, P, and R keys simultaneously immediately after re-starting the system. You must do this before the gray screen appears. Don’t let go of the keys until you hear the startup sound for the second time.)
    • the problem should be solved..FINALLY!!


    Thanks to for the help!

  • amandepp Level 1 Level 1

    another new revelation


    I connected remotely to my macbook... wirelessly

    However when I opened firefox(on the macbook- remotely) I couldn't connect to the internet(the problem).

    Can anyone shed some light why I could connect remotely through wireless???


    I assumed when the wireless drops then the remote connection shouldn't be established too...

  • greenkie Level 1 Level 1

    Others have confirmed that the "connection" icon isn't really accurate.


    However, I have lost internet connectivity while having browsers open and streaming from public radio online, and the streaming did _not_ drop while all other connections did.



    I recently broke down and purchased the newest airport extreme base station and no longer have connectivity issues. This of course means I cannot take my MBP out into the real world and expect to have connectivity.
