Am currently experiencing bizarre WiFi behavior from my MBP 2.16 CD2, late 06 modle. When I go to my T-Mobile Hot Spot account, I usually get disconnected after less than 5-10 minutes, esp. if I am idle for a couple minutes. Have never had this behavior before with this MBP. Usually T-mobile connection is very reliable. Have had this happen at several different locations within the last week or so. When I refresh home page, browser will not find the T-Mobile log-in page. I actually have to restart MBP to get back online. The only thing I can figure is that maybe my recent Apple software updates has caused this. Maybe 10.4.10. Just thought I'd share my experience to let you know that it's not something wrong with new MBP hardware.

Are you running with MBP plugged in to AC power? I don't have the problem when powered by AC. The problem happens after running on battery for about an hour or so. Airport connectivity drops to zero bars and it doesn't come back. It can happen after I click a link or sometimes when doing absolutely nothing.
My fix is to turn Airport off and then on, which brings connectivity back.
Also having WiFi problem. I can connect to my Airport Express base station, but it eventually loses the connection and I have to manually reconnect - it will work for a while and drop the connection again. All other Devices: PowerBook G4, Tivo, Windows XP Laptop, etc. do NOT experience connection/dropping connection problems.

There are also some threads in these forums dealing with a similar sounding issue on the MacBook (-Pro). Mine is a black MacBook with an identical sounding issue to what's described in this thread. I actually got the reseller to take back the first one I got and swap it, thinking it was an actual defect and not a feature, only to find that the new one has the same issue.
A few other specs for comparison:
- I'm currently running Parallels 3188, in the process of updating to 3214 and will see if that changes anything.
- I also occasionally get a kernel panic when using wifi and have to do a hard reset.
- iBook works fine with the same AP.
- My AP is a 2Wire DSL router, so the issue doesn't appear to be specific to the AP brand / model.
I dowloaded the airport utility put out by http://www.macstumbler.com, though I actually installed it through darwinports (sudo port install airport). When my MacBook drops the wifi connection, if I then run 'airport -s' to scan for access points, my connection comes right back. If I don't do that, the only thing else that works is rebooting the MB. Rebooting the AP or turning off and on the Airport has no effect.

I echo the problems discussed on this thread and called support to create a case today. I have three computers - one PC, one PowerBook G4, and a relatively new MBP. Over the past several weeks I noticed my MBP internet connection was horribly unstable when I ran off battery power. When I'm plugged in it is fine. This has been since upgrading to 10.4.10. I have had the "new" blue screen of death twice in the past week - the grey curtain falls and kablooey! Rebooting, sending error report back to Apple. I hope they fix this soon. I don't want to travel with this problem.

after reverting to 10.4.9 i still managed to get a kp after about a week. on my fourth call to apple i finally got a level two person who said he wanted me to send in my computer. i sent it in and they replaced the main logic board, the airport card and probably some other stuff as well. since i've gotten the computer back i have not had a kp but i'm still reserving judgment on whether it's cured as i haven't run on battery much since. fyi, before i sent it off my airport card had the same firmware version as yours, 184.108.40.206, but it came back with the earlier version. 1.0.47.
I may have found a solution for some users.
I have a D-link 604+ router which I have been happily been using for the last few years for my PC laptop.
I bought my shiny new Macbook pro last week and found to my dismay that whilst on my pc I was getting 3-4MBS wirelessly, I was 200kps on my Mac.
After much playing around with the TCP/IP setting on the Mac, I was getting nowhere.
I then have a look at the configuration on the router.
I found there is an option called turbo under the wireless settings. This has always been on, as I thought it just speeded up internet access. (I have found out this weekend, that this relates to turbo speed if you have a D-Link wireless card).
I turned off this turbo option and hey presto I am now getting 3-4MBS on the Mac.
I am not sure whether this a turbo option on other makes of routers, but it is definitely worth looking.
I am a happy Mac user now

Does anyone know if the recent Airport software update solves the problem? If so, I could update to 10.4.10 and apply the update. If not, I won't! I had several kernel panics relating to the airport software (as far as I could understand from the log), so I re-installed and upgraded to 10.4.9 only. I have had no problems whatsoever after that. I really don't want any kernel panics!
Chris Birch and others,
opened Terminal and typed
%> ping 220.127.116.11
I left this running until it had done around 500 pings and then pressed ctrl-c to stop it. It reported that it lost 25% of the packets. A quarter of the network traffic from the MacBook Pro is lost, so no wonder it has problems.
Interesting indeed. What I am also wondering if this affects the quality/integrity of the system upgrades we get from Apple. I regularly get up to 15 Rcv/Send errors after a mere 20 minutes of wireless activity.
MBP Pro - 1 month old. running off HughesNet satellite BBand, via Linksys WRT54GL wireless router. All other machines on the network operate well - even dreaded, older Win machines (well, for a change, I am starting to yearn for some of the well established Win stuff - such as Wintel machines VERY quick way to connect to w wireless network!).
Back to those errors: I have of course already downloaded several upgrades via wireless connection - I wonder what happened to downloads with several (or dozens of) Rcvd/Send errors: are those errors accompanied by re-send or re-receives to make it allright?? Should not upgrades downloaded thus and applied be flagged upon application to the system as corrupted???
I'll - perhaps others will also - appreciate input. It's good to download and apply upgrades, after all, but what if they are corrupt???

said, the only way any bug will be fixed is to open an AppleCare ticket about the issue so the issue is passed along to engineering. These are user to user forums for soliciting help from fellow Mac users, not a way for issues to filter back to Apple.
William, I think you are right of course. BUT, it remains that all the folks here who put real money into their Apple equipment HAVE spotted something not working right. I detect that most of them are actually not clueless re: computer operation.
To them - and me - under most circumstances, one should be able to fire up a computer and connect it to a network (and have it STAY connected) with a minimum amount of fuss. PERIOD - at least that's what prevails in the Win world in the case of connectivity, and that's what's being bragged abouth in the mac world. MBP to say the least IS unstable in regard to communication, and it is in my opinion up to Apple - with its 5% market share albeit much larger share of the mindless hype market - to make its ware work with the prevailing standards out there. After all, most of us here do or will connect with predominant non-Apple world and equipment out there. Many of us also are networked with other computers - Win mostly of course - which do the real business work, while we play iTunes, make movies, etc...
I am of course new to Mac - 1 month with my new MBP. I got the machine to experiment with its vaunted a/v/imaging capabilities: instead, I have spent the better part of the month hanging around various forums, communicating with many rather patient and very nice folks, concerning very basic wireless networking issues. So far, I like the MAc OS quick bootup sequence, and I appreciate not having to worry about Norton Security, Webroot Spysweeper, et...
I did place a call to Applecare once regarding DiskUtility>DiskImaging tool, looking for an onboard way to back up. I do have .Mac and I know there is a backup system from that subscription. RE: Imaging Disk, which I got an error message about, I was told to just "reinstall the OS"... What? Just like that???
Instead, I learned on these forums that the Imaging tool MUST be used from the Install CD. Glad I did not listen to Applecare!
I will personally make an effort to log wifi incidents with Applecare, as gathered from 4 major AppleMac forums, and also the large amount of Rcvd and Send errors I get all the time via Airport when downloading: I wonder what those errors do the integrity of the system upgrades downloaded from Apple? Anyone knows?
As to the "Geniuses" at the Apple store, well... I'll give it a shot of course, nevertheless!
