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

Pinging my NAS while copying a large (700mb) file from the NAS to my macbook pro 2011.

Doing the same on MacBook Aluminum Late 2008, 0% packet loss. Same network, same settings...


The interesting thing is, that both of them achieve the same network throughtput, 9-11mbytes/sec.

(MCS Index: 15, Transmit rate: 300)


Before the update I had maximum 7 mbytes/sec transfer speed on my 2011 mbp and also had the fluctuating ping problem, which was resolved by the update, however I never noticed weak wireless connection or connection drops before or after the update.


When not copying pings are normal (after the software and efi update) or almost the same as on the 2008 macbook to anywhere.

After installing the software updates, there was a day without dropped connections, but now another dropped connection has just happened.


I'm wondering, however, if I have a different problem from some other people here. When this connection drops, I can't reconnect at all to LAN. (Other computers on the LAN are unaffected.) Has anybody else had this particular problem--not being able to reconnect to the LAN at all after the MBP loses its connection?


What happens after the disconnect, specifically, is that Airport now shows the LAN among the networks it can see, but when I click on the network name and enter the password, the password prompt window just pops back up again (no matter how many times the password is entered), without ever connecting to the network.


By the wat: the LAN uses a WPA2 password, set to mixed 11b+11g.


All suggestions very welcome at this point!

I've solved my problem with weak connection by changing router to the airport extreme. But have the same issue with lost packets while transferring file locally.

Card Type, Firmware and Boot Rom Versions are the same, but SMC Version is 1.69f1

See the issues is this, while transfering from internet, ofcourse you can not reach high speeds, and hence the link saturation is low and you are not seeing drops, same as people are not really seeing many issues on G networks. something with link saturation. I think its firmware related. I wish some one with new iMacs can do the same tests.

Hi guys,


I could only test the transfering of big files in my Windows Network as I dont have a network here with Macs..( my macbook is the only one and I am not using a timecapsula....only use the MacOS network between Macbook and the apple TV.


And yes...that killed it completely....


I transfered a folder with photos from my Macbook ( Windows in bootcamp) to my Tablet PC in the local Windows 7 network over Wirelss Lan. Means I tried to do it...


Results:

Foldersize 23 GB

estimated transfer time 5 hours

Speed between 1.08 and 1.12 MB/Sec


Whilst running the transfer every single pingtest in Windows failed. 100 % Packet loss.


Not even normal surfing was possible, impossible to come to the websites to start a stream...

Quiete horrible!


Good, that I do my backups on my dockingstation via USB... I think under that condition to use time capsule is not to possible is it??????


Stopped the transfer and everything worked again perfectly at once .....


Found in some of your older threads that the former modell had problems like this as well????? And its not solved yet... Pah, thats not a good light on a shiny company????


But now tell me, whats the difference when I stream a movie from my Macbook to the apple TV over my network ..its big amount of data as well and that works without problems...!!!?????

I am not an technical expert... the technical expert in this house is in Chicago at present and only back home on Saturday... see what he will say to that...
