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

A:

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...

    Reseting PRAM and SMC is not a valid solution for me. I´m waiting for an official communication and fix.

    New 2011 15" Macbook Pro, last week.

    Trouble since the first night I got it home, connecting to any wifi network (both in OS X and Win7). Have tried everything I can find, removed all keychains (this doesn't affect Windows), have reset the PRAM and SMC. Changed and tried all number of settings on my router (I don't even see why I SHOULD have to do this). Still having trouble, no other machines or devices I have get any trouble connecting to my network, or the networks around here.

    Only this machine. Sometimes it does work, but not for long, the connection will drop and won't re-connect. As far as I am concerned (I'm a technical engineer at an IT support company, I pretty much know what I'm doing), its either a hardware or firmware fault with the WiFi card. Now, this is the first Macbook Pro I have owned, so I'm just looking for a bit of guidance.

    Return to the Apple store for a replacement? Wait for a firmware update? I understand that the WiFi card is proprietary ( Broadcom BCM4331 ), is it replaceable with another vendor? Will the Apple store just provide me with a new card, and I can swap that in-store?

    Unsure what I should do, this is the only problem I have with this machine.

    Noman84,

    Turn up airport debugging on the MacBookPro the next time you cannot connect to a WiFi hotspot. Most hotspots run with OPEN+NO encryption with a Web portal Authentication/Backend, so really I would be surprised if your MBP cannot connect to that type of network.

    Anyway, to turn up airport logging in Snow Leopard open a terminal and issue the following command:

    sudo /usr/libexec/airportd debug +AllUserland +AllDriver +AllVendor

    Note the time, then reproduce the issue.

    Go to the kernel.log and post the entries from about 2 minutes before you reproduced the issue to about 2 minutes after.

    To get to your kernel.log you can use the console app in utilities. Look in /var/log

    To turn off airport logging issue the following in a terminal window:

    sudo /usr/libexec/airportd debug -AllUserland -AllDriver -AllVendor

    Lets start with that and see what we can see.

    Any instructions for debugging the issue for Windows 7 ?

    ... the service center ran diagnostics on the MBP twice and told me everything is working ... and I know ppl with this issue have contacted an authorized service center and / or a genius and were told that its working ... there are several posts with the logs posted and latency tests (ping delays) posted everywhere, refer to this thread for pings and other details on the issue, there are other threads also:

    No news from my side, but I am very glad to know in the meantime ( alone 48 posts here in my thread about a wlan issue on the new Macbook pro 2011!)that I am not the only one and that I am not just too stupid to connect a Macbook to the network...where all our other divices are running without any problems.

    Still same issue! Macbook has got trouble with the weak net. I think, the reason why there are not many more complains might be, that the problem is not occuring when you have got a very strong net. I did not have any trouble at all at home in Germany sitting nearly beside of our router with a full blast of a 32 MB Wlan connection.
    Here in our hotel wlan the conection is much slower and weaker. BUT as I said, the other devices as four different Windows Mashines, my Ipad and Iphone and the HTC of my husband are able to connect on that net without trouble. Its slow and weak but it works for the other ones. Only my Macbook gets thrown out frequently. I have to restart the wireless adapter to get a connection from time to time, than it works for a while and than its gone again.... Very very unsatisfieng with a brandnew notebook. I will try if I can get the update working now...but I have my doubts...on this connction level at present, downloading anything is a mission impossible.

    I found something.

    Kernel log extract:

    Mar 24 09:32:25 MacBook-kernel[0]: wl0: Beacon Loss Event
    Mar 24 09:32:25 MacBook-kernel[0]: AirPort: Link Down on en1. Reason 4 (Disassociated due to inactivity).

    Since I have seen this, I am connected with some artificial traffic and no more suddenly connection drops (for 20 minutes at least).

    Maybe is a power management bug :S

    There is another mensage that concern me at Airport switch on:

    Mar 24 09:26:01 MacBook-Pro-de-Diego-M kernel[0]: en1: setting diversity to: -1
    Mar 24 09:26:01 MacBook-Pro-de-Diego-M kernel[0]: en1: Error configuring antenna diversity (index = -1).
    Mar 24 09:26:01 MacBook-Pro-de-Diego-M kernel[0]: en1: setting tx antenna: -1
    Mar 24 09:26:01 MacBook-Pro-de-Diego-M kernel[0]: en1: Error configuring transmit antenna (index = -1).

    Could be another bug?

    This is good I was thinking power management issues early on but dismissed it. I`m wondering what is that second error ?

    I'm also suffering from this issue. Initially I had a lot of disconnections and low speed, but after I changed the channel in the router configuration, the disconnections are now rare. The connection speed however, it's slow (200Kb/s) but a least I can surf the web. I'm going to try linux on the machine to see if is a hardware problem or an driver issue.

    I was standing at my computer, typing on iChat, with uTorrent running in the background, and the signal dropped.

    For some reason the wifi chip just times itself out completely randomly, even with a program designed to use internet nonstop running in the background

    What wireless router are you using and are you seeing these drops frequently ?
    Everyone who complains here needs to at the very minimum, post their Wireless Router make and firmware version's so if there is a trend with a particular make/model it's easy to figure out.

    Have you also tried changing channels and using a less congested channel ? Have you checked if your router is running the latest firmware version ?

    I am running on an Airport Extreme Base Station that has worked flawlessly for a year. I had an early 2008 Black Macbook that I sold to buy this new Early 2011 Macbook Pro and it never dropped its wifi connection ever.

    Taking Macbook Pro to Apple Store tonight, Im sure they won't be able to reproduce the issue.

    BT HomeHub 2.0 fw: 8.1.H.J (Type A) - Tried: none, WEP, WPA, WPA2

    Have tried a number of different routers, I'll get those in a bit.

    Note: I have also re-installed OS X and Win7 twice.

    Everything else ... even 4-5 year old laptops connect just fine ... IMHO i do not think this can be a router issue. Also, how do you go about determining which router / firmware they have at the hotel / restaurant you want to connect to WiFi on ? ... also, when you connect an external USB Wifi device to the MBP it connects to the same network (and the same router) just fine.

    Even older Macbooks with the latest version of OS X connect without any issues and MBP 2011 refuses to connect or drops out.

    Trying to connect on Windows 7 is even worse, its probably a hardware / driver / positioning of the NIC issue. The issue happens for open / unsecured / unencrypted networks as well.

    The Wireless card by Broadcom that is used in the new MBPs is relatively new and possibly not well tested, I can only hope its only a driver issue and not a hardware / device issue.

    Im starting to think that it is a hardware issues. Also its posible that its a bad batch of cards. I wonder if there are people who dont have issues, but its hard to access as they wouldnt come here. Also since it is an issues randomly people might not notice right away. If it is just an issue with card they can replafe the card i guess.
