I've got an new idea about the wifi problems everybody has.

Apple Service told me to reset PRAM and SMU. I did and also uninstalled rEFIt.

Since then i didn't have even one wifi drop.

Yesterday ubuntu 11.04 was released, so I installed rEFIt, next time I booted up OSX wifi drop's are back.

so same thing again. deinstalled rEFIt, reset PRAM and SMU.. no more connection drop.

i hope you guys can confirm this behavior.

maybe all people having wifi issues who installed rEFIt and those who say everything works fine didnt ?!

No refit here and judging by the number of people new to macs posting with problems I doubt refit has anything to do with it

Hi guys,

I am also affected by this problem. The funny thing is that I recently sold my macbook from 2008 which had exactly the same problem. Somebody in this forum found a fix where you just downgraded the firmware-driver files for the wifi-card to 10.6.4 version of snow leopard. So this was defenetly caused by the software and not the router or what ever. Now I am confronted with the situation that my 2 weeks old macbook pro has the same problems, but I can not use the previous fix, because in 10.6.4 there was no driver incuded for the recent wifi-card. What the **** is apple doing with us? What would you guys receomend me - do realy think therer will be a fix within the next couple of weeks or month? I mean the original problem with the older machines appeared the first time with 10.6.5 and is still unfixed. So should I returm my macbook pro and get my money back - I mean apple is obviously giving a shxx on our problems - they just ignore it which is impudence!

Hi everybody,

Have the same problem unfortunately.

I discovered that this non-stable ping results have place only when the wifi signal is poor. And I found that the sensitivity of card in new gen of MacBook Pro is much less than in previous gen (2010). So when my MacBook Pro (2010) shows the data rate 130Mbps stable (I`m using 2,4GHz), new MacBook Pro 2011 at the same place shows the fluctuation of speed 39-130! As a result if the signal is lower, MacBook Pro 2010 have link speed about 50, but the new one 5-10 only, then ping fluctuation is starting and it`s impossible to work. When the data rate more than 26Mbps - ping is stable. Do you have the same problem with sensitivity of new MacBook Pro airport card?

I'm also experiencing the same wireless drop-outs on my new Macbook Pro 2011 15". This is my first Macbook Pro and I'm using the very same wireless setup that I use for my various other non-mac laptops etc and this is the only machine that is experiencing the drop outs.

I really hope Apple hurry up and acknowledge there is clearly an issue that needs to be fixed here!

Anybody know Is there any possibility to downgrade firmware of wifi card to previous one, that used on macbook pro 2010?

I don't think the previous 2010 version drivers had support for this card, after a little messing about I was able to load the drivers but in system profiler no wifi card showed up.

I thought cards are the same in previous and new generations of macs. It is not?

Hi I'm experiencing the same problem as you guys.

I have MBP 2011 15" C7 2.0 with 10.6.7

For the Accespoint router I use Cisco linksys WRT54G2

The ping result is quite the same, up and down..

And sometimes I lost connection, My Wireless network setting (airport) was saying that the MBP still connected to my Accesspoint, but I can't ping the accesspoint IP.

When It happened, I must shutdown the airport and turn it back on (disable enable), or power cycle my router (Either one will work)

(I'm not sure this is related), but I don't realize this problem until 2 days ago, the previous day I run some "software update" from the mac. I forgot what's in it, but some stated as Security update, or something.

I wonder if I can roll back those Mac OS update installed 3 days ago. Any idea how ?

And also I have tested with my IPad and other laptop (Dell Inspiron running on Windows 7) connected to the same access point, they runs like a charm..

So I'm sure there some hardware problem, or driver problem on my MBP.

I'm looking forward for Apple engineers to fix this issue ASAP. It's very annoying !!

Bought a 13" Macbook Pro i5 on Wednesday, and I'm experiencing the same problems. Wi-fi is really slow compared to my old Macbook from 2006, and even to my Nexus One, which means this isn't an issue with my wireless router.

Here's one today's better results:

--- 192.168.1.1 ping statistics ---

50 packets transmitted, 41 packets received, 18.0% packet loss

round-trip min/avg/max/stddev = 1.186/14.661/207.152/33.557 ms

I'm getting good at playing snake on youtube...APPLE THIS ***!!!!! 😠

My work needs to buy a new macbookpro 15' as soon as possible! Therefore, please give me an advice? Do you think with macbookpro 15' with serialnumber near now or just produce near now will not have this kind of issue??? Thank you very much!

I think better to address this question to Apple))

Well this morning I visited my local Apple store. I pinged various servers from each of their new Macbook Pros in the store, and all of the new MBP's (in 13, 15, and 17 sizes) exhibited the same erratic response times as my own new MBP. When I pinged the same servers on Macbook Air's that were on display, the responses were all very consistent (and fast!).

The Apple Genius I spoke to about this issue with my own MBP seemed unaware of any issue and was happy to try getting a new Wireless card put in my machine at some stage if I want, to see if it helps, but if all the models in their store are doing it too, it seems pretty pointless for me to go down that route at this stage.

I hope that they will soon release some new firmware for the current hardware to resolve the issue. Fortunately for me, the dropouts don't seen to occur as frequently as they are doing so for some people on here. I might go 3-4 hours without any wireless drop and when it does drop I can usually re-connect (manually) within 30 seconds.

Anyway, here's hoping Apple very soon get this resolved!!
