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.

    Just because other wireless devices connect OK does not mean you should not suspect the router. Is it old? Has it got updated firmware?

    Having the EXACT same problem. The first week my machine was working fine, but now I'm sitting 4 feet away from my router and I can't even get gmail to load.

    Plugging in by ethernet cable fixes the problem, but obviously this isn't what I paid $3000 for.

    What RSSI are you seeing the AP at ? ( Hold down the Option key and click on the AirPort Menu Extra to get the RSSI Value ). A value lower than -75 ( -75 to -96) is pretty bad. Anything in the -35 to -75 range should work very well.

    You all kill me, no, it isn't his router. This is an obvious problem with MBP's and for some reason no one wants to acknowledge it. Why won't Apple come up with a fix?

    With any luck this is just an issue with drivers and they will post an update in a week or so.... **Crossing fingers**

    I have the same problem as well. The connection between my Level One router and my new MBP drops all the time, while my other Macs and PCs at home have no such problem.

    However, if I switch to my old Aiport Extreme router, the problem is gone.

    One more thing, when I connect my MBP to the router in Windows 7, there is no problem at all, therefore, I think the problem lies in Apple's software

    I've noticed similar behavior - specifically with the new 2011 MacBook Pro 13 and 17" models (tested) on Cisco infrastructure - using a 1252 and 3500i/e series APs running in dual-band mode, with 5GHz preferred. I've seen the transfer rates when in close proximity to the AP move between 72mbit and 243 - occasionally 300. My 2010 system in the same position is a solid, dependable 300.

    They did modify the wireless chipset in the new 2011 MacBook Pros to replace it with a true 3x3 802.11n device. Cisco have long praised the Broadcom chipsets so I will see if their wireless team can advise me on what this new gear is capable of.

    I currently look after a very large deployment of wireless LAN equipment so my wireless performance is absolutely critical to my work - the 2010 system was a godsend and a testament to how wireless devices should be built. It looks to me like this could be a software issue so I only hope Apple resolves this ASAP. I'll hang on to my 2010 system for now...

    Very doubtful it's the router when every other device works perfectly. My 2008 worked fine on my Cisco router but now my 2011 MBP drops every few minutes on wi-fi.. At the moment i have to use the Lan cable..

    Iphone and wife's PC connect just fine over wifi..

    Clearly needs a fix, lots of people seem to be affected

    I have a 2011 MBP 2.2 and get perfectly good wifi reception at home with my airport extreme. At the moment, I'm in a library with some other router and keep losing my connection. And when it does connect, it's quite slow, though the RSSI is -49. Everything works perfectly with my iPad, so something is wrong with the software driving the MBP's Airport. Hope they fix it.

    also having the exact same problem. and it also started after a week or so.
    i can´t stand it. if a software update can fix this, they´d better be fast.
    multiple older macbooks and iphone´s and airportexpresses work perfectly in the same network...

    I've been troubleshooting this issue with Apple for about a week now. I have a ticket open with them that we've escalated to engineering.

    It seems to be happening on all the new MacBook Pro's. I've had mine replaced twice already and we were able to reproduce the problem on every new MacBook Pro they have on display at the apple store.

    It is currently suspected that their is probably a bug in the AirPort card's Firmware since we've tested with older MacBook's with the same OS and hardware with the only difference being the AirPort firmware on the older MacBook's is 5.10 and the new MacBook Pro's have 5.100

    I have been sending them diagnostic information which has been sent to Engineering for a fix.

    They are supposed to get back to me early next week with their findings.

    Same here, it is sending me silly. I have almost no range on my wifi using ANY of the routers that I regularly access.

    Please apple fix this ASAP.

    I have been having the same problem - brand new MBP 2011 17", gets a surprising number of bad packets when pinging a dual band airport base station with latest firmware.
