Some of the things you may have already tried - First contact your ISP. You need to confirm that the issue is not on their end.
Change your router channel. Sometimes this is all you will have to do.
Power cycling the router. Read the router's user manual or contact their tech support for instructions.
System Preferences/Internet & Network/Network
Unlock the padlock
Highlight Airport and/or Ethernet
Click the Assist Me button
In the popup window click the Diagnostic button.
System Preferences/Network- Unlock padlock. Highlight Airport. Network Name-select your name. Click on the Advanced button. Airport/Preferred Networks-delete all that is not your network.
Place a check mark next to "Remember networks this computer has joined." Click the OK button and lock the padlock. Restart your computer.

Check to see if an extra entry is present in the DNS Tab for your wireless connection (System Preferences/Network/Airport/Advanced/DNS).
Delete all extra entries that you find.
Place a check mark next to "Remember networks this computer has joined."

I am having the exact same issue.
I ran the firmware update for Thunderbolt and suddenly I cannot get out on either network interface. I cannot connect to the internet, or local resources.
I am able to connect to various wifi networks, but cannot go further.

I don't think that I have any warenty left on my computer since I bought it two years ago.
And we don't have the same system in Denmark with the Genius-bar.
BUT! a little update regarding my problem. I took my other MBP that connects just fine to the network and found the DNS adresses it uses with the connection. And manually copied them to my own computer.. Then I hit the renew DHCP lease button for around 20 times, and suddenly it connected to my wifi... I restarted to how it would behave, and sadly it diden't connect again, and i hat to start over. But I got i working again. So it can be done... just done know where the the problem is.

I have had the same problems as every other MBP retina user. the solution for me was the following
i have changed my router settings. my only active channel now is channel six. i have disabled the auto channel configuration. this is a solution that works for a lot of people.

Same for me people, for a couple of weeks now I'm experiencing time-out problems on more than one MAC OSX notebook at different networks. I tried to change the network packet size in the network adapters MTU setting to a lower value e.g. 1453, but it did not completly solve my problem. My VPN connections fail. I'm running Windows on a different computer and even virtual on my MAC OSX notebook and the Windows OS doesn't have this problem and works fine. So the conclusion to me is that some stuppid OSX update must have broken our network adapter drivers.
So @ Apple I say: get this annoying bug out of our lifes or I switch to Windows again.
Thank you all for your time, and good luck with the bug!

I've had the very same problems with my Macbook Air since i switched to Lion and i had tried every tips and tricks available without much success so far :
- create new location
- delete saved wifis + keychain
- change MTU
- remove preference files
Yesterday, i noticed in activity monitor that many programs were running in the background (novacom drivers, Android file transfer agent, Google keystone...) which i did not want.
Then i decided to go to CleanMyMac to uninstall them as cleanly as possible. I could not find them in the main "App" tab, therefore i clicked on "Others" and... light came.
I had 83 "Others" old program bits and pieces scattered in folders such as Library, LaunchAgents or LauchDaemons. Those plist files belonged to Softwares i did not use anymore but my guess was that they were still loaded at boot time and could lead to problems.
After a good cleanup i went down to 7 remaining plist files in this tab and as a side effect : All my wi-fi problems were GONE
Yesterday was a good day!

I have a MacBook Air. I was able to connect fine yesterday evening. Ran into problems just this morning where the connection would timeout. I completely rebuilt my router settings from scratch with no luck and finally came to this post.
I followed jarnomelenhorst's advice and changed to a static channel and things are working fine now...thank you. Yuck, yucky, yuck, MacOS bug.

I am experiencing now wifi timeout too....
I purchased a film on iTunes and after 1.6GB of the film, when there was still the iTunes Extras (1.3GB) to be downloaded, my wifi (despite the fact that I saw the signal icon all black) was on without being able to connect to the internet.
I thought it was the wifi modem, and I switched it off and then on.
but after another 1GB of download, the same happened.
Then it occured to me that maybe the wifi modem was ok, and then I tried using internet via my iPad, which proved the origin of the problem was my MBPro Retina (the model before the 2012 september launch).....
I have mavericks and everything up to date....

That is for the tip! My solution was slightly different but you took me about 90% of the way there.
For those of you that aren't able to connect by follow liskabee's advice, try connecting to your secondary and/or guest Wifi connection. That immediately solved my connectivity issue.
Hope that helps!

This thread is a bit old but I just ran into the same issue and came up with a fix. On my wireless access point (uses WPA2 encryption) I changed the settings from using TKIP to AES and that fixed the error that I was getting. For some strange reason Mac does not support TKIP. Good luck hopefully this helps anyone who is having this issue!
