Hello, I have a macbook pro and the wifi will simply drop after about 10 - 20 minutes of use. The wifi signal strength will continue to show 5 bars, but at this point the network is totally dead--I can't ping the router anymore. The internet itself is fine since my iphone can access the internet just dandy when my mac is chasing its own tail at light speed. Here is some system description stuff that might help, OS Version: OS X Leopard 10.5.4 Darwin Kernel Version 9.4.0, xnu-1228.5.20~1/RELEASE_I386 (Obtained from issuing "uname -a" from Terminal [Applications/Utilities/Terminal]) Model Name: MacBook Pro Model Identifier: MacBookPro3,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.4 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 4 MB Memory: 2 GB Bus Speed: 800 MHz Boot ROM Version: MBP31.0070.B07 Wireless Card Type: AirPort Extreme (0x168C, 0x87) Wireless Card Locale: USA Wireless Card Firmware Version: 220.127.116.11 Current Wireless Network: XXXXXXX Wireless Channel: 1 Wireless security is via WPA using 802.11G Here is some history that might help, 1. About a week ago, I gave my apple in for repairs because the keyboard and trackpad were dead--they replaced those parts and I got the computer back. 2. before this repair, I had no problems with my wifi dropping. And here is stuff I have already tried that have *NOT* solved my problem: 1. System update (nothing to update) 2. Changing the service order of the Airport Card (moved it to the top) 3. Clearing the KeyChain to avoid password resolution problems 4. Changing user account to a fresh one incase of stale/bad user defined configuration data 5. Watching Console for many many hours reading the system log outputs... No kernel panics, nothing shady... 6. Upgrading the firmware on my router to its latest version 7. Checking the access control to my SSID's entry in the keychain, currently SystemUIServer, AirPort, System Preferences, and airportd have access. 8. Cooled my computer to a block of solid ice to avoid "Heat problems and packet loss issues" which has been mentioned online in several places. 9. Changed the Energy Performance settings to make sure there wasn't some kind of "sleep" issue with the airport card And here is some solutions that have crossed my mind that I am not keen on doing at the moment: 1. tossing the macbook out the window 2. burning down a genius bar--every time I go there, they tell me things I already know and get stuck way before I even got stuck. I just politely stand there and smile and pretend to be a dimwit and let them have their ego boost. 3. .... jokes jokes... I have to stay light hearted you know, this is extremely frustrating Please for the love of god if anyone has a solution to this help. At this point I don't know if its hardware software, firmware or anything for that matter. I don't even know how I am going to convince the "geniuses" that its broken... they will just say "looks like its working" and send me home. My sneaking suspicion is they screwed something up while servicing my keyboard, but how do you really make a case for something thats intermittent? Are they simply going to say "oh we believe you, we'll swap out your airport and if that fails, then your whole system"? sorry for the long post.
