Q: new macbook pro 2011 weak and dropping wireless connection

Just looked throught this part of the forum and found out there are a lot of people out there which seem to have the same problem as me.

I purchased a new modell 2011 MBP on the very first day from our apple store.
At home, sitting directly beside the wireless router I didn´t noticed anything wrong.
I have got beside of the Mac OS a bootcamp Prt. with Windows 7 on it and everythign works fine so far.

Five days after purchased I started traveling on business and at present we are for some weeks in Melbourne. Were having a wireless connection in our appartement and here I have got massiv problems with my connection.

We are having altogether four windows mashines with us, my IPad, my Iphone, another HTC smartphone, and my new Macbook.

All the other devices connecting to our room wireless without problems. The net strengh is not fantastic but the other devices bringing it up to four bars on the windows wireless symbol in the task bar. None of the other computers where ever loosing the connection.

Only my macbook can not make it over three bars and its going on and off. Donwloads fail freuquently because the conection is interrupted more than one times..
In my opinion this problem is even worse on the Windows OS and a bit better but far away from beeing good and acpetable on the Mac Os.
I hope its only a driver issue and there is no hardware problem with the new mashine. Other than this I love the new notebook and I am very satisfied with its performance.

Iphone 4, Ipad 1 ,Macbook pro 13, I 5, 8GB, early 2011, Windows 7, Mac OS

Good morning,

Needed a moment to find my thread...the new structure...if there is any at all left is not very comfy to find your way around her in the support forum, I find....

 

News from my side....

Back home in Bavaria, back in our 32 MB Net. MacBook does not drop connection not on Bootcamp not on Mac OS Becuase of the strong link. if you look on the wireless symbol everything looks fine.

BUT

- Doing the ping test shows same horrible result like everywhere else before. Ping is going up and down, shows tomeouts.

-Downloads are very very slow considering our net speed.

-Streaming absolute NOT possible.

 

My old Fujitsu T4215 and all the other Wndows Mashines my husband uses in our net are working without any kind of problems...but we know this already, don't we????

 

I was visiting our local Apple supplier yesterday, with the paperworks about the work which was done on my MacBook in Melbourne, change of Networkcars, wihtout any change to the better.

 

Her suggested to call apple and tell them to change the logiboard next and so I did!!!! On Monday I will bring my MacBook to the apple store. Than it gets send in and I have to live ten days wihtout it.... fantastic....

 

Will keep your informed if it helps....I have got my doubts BUT what wcan we do...

    Yes, I think that pretty much sums it up anguish, everything points to it being software related and hopefully it means a fix for snow leopard isn't too far away.

    I did it manually (with right permissions) and just checked with Kext helper b7.

     

    No luck either way.

    After installing the extension, tried to manually load it with kextload command and got this into system log:

     

    May  2 17:59:19 macbook kernel[0]: kxld[com.apple.iokit.IO80211Family]: The super class vtable '__ZTV20IOEthernetController' for vtable '__ZTV17IO80211Controller' is out of date. Make sure your kext has been built against the correct headers.

    May  2 17:59:19 macbook kernel[0]: Can't load kext com.apple.iokit.IO80211Family - link failed.

    May  2 17:59:19 macbook kernel[0]: Failed to load executable for kext com.apple.iokit.IO80211Family.

    May  2 17:59:19 macbook kernel[0]: Kext com.apple.iokit.IO80211Family failed to load (0xdc008016).

    May  2 17:59:19 macbook kernel[0]: Failed to load kext com.apple.iokit.IO80211Family (error 0xdc008016).

     

    It seems there are dependencies between libraries.

     

    Could somebody link IONetworkingFamily extension from Lion just to test?

    I uploaded the ionetworkingfamily kext http://www.kexts.com/downloads.php?do=file&id=1161

     

    If that doesn't work you may consider just copying the updated broadcom plugins from the io80211 kext into your regular 10.6.7 io8011 kext (and leaving the 10.6.7 ionetworking family kext stock).

     

    Good Luck!

    I was experiencing the exact same symptoms.  I called Apple support.  The guy had a fix for me: apparently Apple has dropped support for the WEP password protocol for wireless networks.  Both the networks I was trying to connect to had WEP passwords.  This is what he had me do:

     

    Went to Keychain Access > Preferences > Reset Default Keychain

    Then restarted, connected to the network.

    Added $ before the password (which was all numbers).

     

    After this, it connected like magic and has been working for four days!  Hope this helps.

    Keeping the old files with the new plugins doesn't work, tried that already ;-)

     

    Installed the two kexts IONet and IO802 and doesn't work either.

     

    I will try playing with version numbers inside plists to see if it helps.

    Sean?

    Are you one of them with the problems with the external  screen connection as well? Found the thread yesterday here in the forum. Through all my traveling and now the seventeen days repair of my Macboook I did not find the time to connect my new MacBook to my workstation at home yet...is there the  the next problem waiting for me?????

     

    I mean only for the case I am getting my MacBook back one day, anyway....

    Got a mail yesterday from my apple shop and they told me the technician guy from the  repaircenter had called and could not offer a solution...there is nothing what he can do..... They asked my for being patient...

     

     

    Dont know what to do...I am getting really doubtful if I want to live with this any further.

    Next week I have a trip to Chicago planned and need a working notebook with me.

     

    My good old Fujitsu T 4215. starts rattling the Van again which is the clear sign that it needs a repair again

    ...somthing I did not want to  invest into it anymore...

     

    And no solution anywhere.....

    I just wanted to post a quick update, following my post of a few days ago when I mentioned I'd been to my local Apple Store and all MBP's in there had erratic pings.

     

    Whilst I was there, the only thing that one of the Genius' suggested I do (before starting to order in new wireless cards etc) was remove all of my existing network configuration/settings. I had already manually removed the Airport from my network setttings and re-added it, numerous times, to no avail. However, he removed an entire folder from somewhere. I'm a MacOS newbie so I'm not sure exactly where it was he did this, I just saw him go to a certain path in Finder, deleted a configuration folder, which rendered my network settings entirely empty when he opened them up. He then re-recreated my 'Location' (as automatic), at which point all the standard items were added (Airport, Ethernet etc.). He applied that, and sent me on my way. Now I'm still not 100% convinced that this really achieved anything - certainly not in terms of the erratic pings as they remain, however, since that trip to the store on Sunday, I've probably been using wireless back at home for at least 10+ hours and so far, I've not noticed the wireless drop at all! This could just be total coincedence, but I was previously getting drops anywhere from once every 20 mins (this only occurred a couple of times) to once every few hours (more typical). I'm still half waiting for it to start dropping again, but so far, so good.

     

    I'll continue to post any updates on my situation over the next week or two.

    Hi Starnzy,

     

    Did you try streaming something?

    Thats the best test if everything works fine in my opinion.

    My macbook was sitting beside of a 32 MBnet, brandnew  wireless router and was not able to stream anything, not from the internet( Mediathek of Germany TV channels f.e.) or containts of Itunes Mediathekt to the Apple TV. Nothing works.

    Just surfing is alright, slow, but it works. But uploading somehting failed as well. Could not even get a photo up to Facebook.

     

    I did not have trouble to connect or had any dropouts here at home with our fantastic net. Only on my travles, the weaker the net gets,  the worse it is. Our windows mashines worked everywhere...on all the places where I had no chance to connect with my new Macbook at all. Or when it connected, than it disconnectend every five minutes...independent if it was running in OS or Windows 7

     

    Its sad...

    You can`t streaming even when you have strong wifi connection? How much is RSSI at that moment?

    Hi Lara,

     

    I hadn't tried streaming, so this evening I've been streaming some 720p (5gb) videos via wireless. I let one run for 20 mins and I had no interruptions or stuttering etc. I then tried another 3gb video file and have been using the slider bar (VLC player) to skip forwards and backwards, to give it something to think about, and its been keeping up fine. So far, so good... though why it's suddenly behaving itself I really don't understand - still, I'm not complaining...

    I guess I will add my name to the list of people having problems. Sigh. I am also a 1st year law student, so this is more than a little annoying.
