I am experiencing exactly the same problem that you describe in your post for the past 2-3 months (probably after a recent OSX software update). I have followed all of the steps that you decsribe in order to resolve it but with no success. I have tried with different wi-fi networks and modem/router configurations and the problem has not been solved.
I have a late 2006 MBP (MacBookPro2,2) with MacOSX ver 10.7.5 installed.
One possible solution is to create an open wi-fi network (no WEP or WAP security) and restrict clients accessing it by enabling MAC filtering.
Hope that Apple finds a solution for this issue and fix it !
If you call Apple Corporate, ask for Customer Relations, they will give you a new computer.
If they have to give you a new computer, it might push Apple to fix the problem. If you 'suffer in silence' by trying all the options, leaving messages here ..... APPLE DOESN'T LOSE MONEY AND DOESN'T GET THE MESSAGE !
Why not help force them to fix by demanded a new computer. Many on this site have done just that. It's not a big deal - in face, in most cases, we have received our new laptop THE NEXT DAY - as Customer Care instructs the Apple store closest to you to give you a brand new one.
I'm surprised how many keep struggling, especially after I have posted my year and a half problem, which ended the day I called Customer Care. The next day I had a new laptop - THAT WORKS.

hi Laurenmay1, when you called corporate and spoke with Customer Care, did they make you go through a whole bunch of tests and configuring of your macbook before deciding to offer you a replacement?
I called corporate today and they put me in touch with a senior tech advisor and they did some configuring with my wife on the macbook during the day and i need to do some stuff tonight and call them back.
Hi Sandals -
In answer to your question: No - they had enough info on file after a year and a half of suffering. Apple Care and the Apple Store did not help at all, and they did not tell me I should call Customer Service. I was so upset, and when I called, mountains were moved within a couple of hours.
If you have tried and tried to fix - they will give you one. If you have no history of trying, they may ask you to try a little. But you must be firm.
Tell them your laptop doesn't work, you've tried, and your done trying. Tell them: 'I would like you to replace my faulty computer. I need one immediately.' Then watch what happens.

I have found ONE solution - which finally helped me, so thought I better post it:
I have this problem with a Netgear router with WAP password, in Australia...
I tried MANY different solutions from these forums, including moving the *.plist to my desktop etc...
I cannot take credit for this solution but:
Macbook Pro, OS 10.7.5
Check the MTU setting on the network's preferences. Mine was at 1500, I set it to 1450 and the problem has completely disappeared!!!
Hope this helps at least some of you!
I'm not a techie, but have been a MAC user for most of my computer life. I have a MacBook Pro and a MacBook on a home network using AirPort. My MBP is working fine and has no connectivity issues at all, but this week my MacBook has decided it can't find my network. I haven't done anything in the past week except update my AirPort firmware. I'm assuming that is what is causing the issue for the older MacBook which is at the end of it's lifecycle and can't be updated any further. But y'all keep referring to router "n" and router "g" and I have no idea what that is...I have a Surfboard router connected to cable internet. If anyone with more technical experience can give me their opinion, or suggestions, I'd appreciate it. I don't know if there is any way to 'undo' the Airport update and go back to the previous version or not.
Thats weird it strted doing that right when you got the firmware upgrade. if your problem is the same most of the users on this forum undoing the update wont do anything, so i'd troubleshoot.
if you do have a faulty mac, apparently you can try and harrass apple into giving you a new one but good luck that tactic blew up in my face and ended up with me losign my warranty and applecare i paid for.
Heres a fix i made that i posted a while back
"The fix I use is tethering my cellphone's wifi to my macbook via the app "PDANET." They have apps for several different types of phones.
*I would advise against using an Iphone, seeing as how PDANET is not available in the appstore due to the app's interference of ridiculous tethering nonsense your mobile providers and and apple try to impose on their customers ...*
After a couple weeks PDANET will try to try to restrict your net use through their app until you purchase the "full version." I literlly (GOOGLED) "pda serial key" followed by my model of cell phone and the first youtube video had a serial key that unlocked the app."
Burning thumb posted something that seems legit but i have yet to try
"In my case it turned out to be a cable issue. There is a cable under the wifi card and because the MBP air vents are so big lots of dust gets in and then works its way under the cable. Take the wifi card out, remove the cable, clean everything, and put it back together.
A repair shop can do it for less than $40 if you are not comfortable doing it."
Apple's trying keep this all hush hush so if you bug them enough and try not to let them take your computer (this is how they ****** me) you should be able to punk a new laptop out of them.....but i dont know. Ive completely removed any feelings of trust towards apple from my life and just am handling it myself
