I have a 17" Unibody MacBook Pro which is about 2 months old; which I use on several WiFi networks (home and several different networks at work).

I also bootcamp the mac with Snowleopard and Windows 7 (64bit).

When running Snowleopard, the WiFi connection will periodically drop and then reconnect (sometimes it will be steady for 20-30 minutes, other times it drops every couple of minutes).

Sometimes it will refuse to reconnect until airport has been turned off and then back on.

The strange thing is, when booted into Windows 7, the connection NEVER drops.

It will run solidly for hour after hour with no problems what so ever; on the same WiFi networks that Snowleopard is constantly losing connecting to.

I have all the latest updates installed so not really sure what I can do; anyone have any ideas?

    Same thing happens both at home and all your networks at work?

    I am having the same problem on my macbook. I've replaced the router already and it happens all the same. My fiance's 13" macbook pro is similarly affected. I do not experience this issue with booting to XP through BootCamp. This is fortunate since that is where I do my gaming, but it is frustrating having to turn airport off and back on every few minutes. When I browse to a slow website, it is impossible to tell if the connection has dropped or if the site is just slow or non-responsive. This is my first mac and it is leaving a questionable impression. I will gladly throw this into the secondhand market and pickup an ASUS if it means I can browse the web without this inconvenience.

    Apple: Please fix this issue.

    I'm sorry to say that I don't think it is going to be fixed. I'm already waiting/hoping for a solution for more than three years. Try to sell it as you mentioned. Apple only wants fanbois as customers

    I'm going to add my own voice of protest to this forum - I've had my macbook for 2 months working on a Belkin wireless N network with 4 other windows devices working with no problems on it. The network connection drops every time with the Macbook - once I've restarted the internal wireless network connection, it's fine. On the one hand, it's good to know that I'm not the only one suffering this, but on the other hand, it's a bit shoddy of Apple to ignore this problem. I'm going to try and be persistent with apple on this issue because it's a shame such a promising piece of kit is so badly marred by what appears to be a fixable problem.

    +1 on this. Has been going on for years with the MacBook Air. Just bought a brand new MacBook Pro 13" and it does the exact same thing when in OSX. Works fine in Win7.

    It is a shame...makes me want to throw this beautiful piece of aluminum sculpture out the window.

    Same problem here (two MacBook Pros and three Windows boxes on the network, only the Macs drop). One possible clue: it just started happening when we moved to a Netgear N router. It was fine with a Belkin N router.

    Having the same issue. I've had my Macbook Pro for about two years but have only been experiencing this problem in the past month or so. I'm guessing it might be due to a recent software update.

    At first I thought it was my router, but all the other computers (windows based) on the network have had no issues at all, even when my connection drops.

    I've tried a few fixes I've found - flashing the PRAM, putting airport at the top of the list, setting my router to use G settings instead of N, putting my router on a different channel - but nothing works! Super frustrating since I use my mac for work AND play and no matter where I am I get disconnected!

    Hi all,

    I also have this problem, exactly as described. I've heard that driver issues tend to work themselves out around the x.7 release (10.6.7 in this case). Let's hope that that's true.

    Not to be mean but it would be more helpful to share more info about your working enviroment like
    Do you use a router?
    What brand?
    Which band is it on (b/g/n)?
    Which channel is used?
    Encryption method?

    just saying it dont work wont give enough info to Apple. I did have a MBP (2009)
    and it worked great with my Belkin N1 Router (using WPA) but seen the drop-out with my other old Compaq pc so i know how annoying it can be.
    I just ordered a new 15" so hopefully it will continue to work great (cross my finger)

    Well I DID answer all of this in my earlier post except for the encryption method. It's a Netgear N router.

    When the problem started we were on WPA2.

    Since we're out in the boonies, we turned security completely off and it didn't help at all.

    Changing the channel has also not helped.

    I'm having the exact same issue on my 13" unibody Macbook @ 2.4ghz w/4gb.
    Wifi works flawlessly in Win7, but as soon as I boot in to OSX 10.6 or Linux (Ubuntu 10.4) wifi drops constantly. I have to stop and restart the airport, or rmmod/modprobe before wifi comes back. I have the same results at home on a DLink DIR-615 running OpenWRT Backfire, and at work on a Proxim mesh. Both environments are running WPA2 PSK.
    Also, my wife has the same issue on her white 13" macbook.
