Go ahead and create a new account and log into that account. Then try connecting to the wireless network and see how long it stays connected. If your problem is gone, then you know there is something wrong with your normal user account. Users have reported that they can connect to a wireless network from their Mac running Windows via bootcamp just fine, but when they switch to OS X, they connection drops.
For example, anti-virus apps or scanning apps or networking monitoring apps, etc. Clear out your system one by one and see if the problem goes away. Not an ideal solution, but better than nothing. Though not a common solution, some people have reported that changing over to a static IP address has fixed the problem. Probably not a long term solution, but it may let you work on the Internet for a few days!
Go to System Preferences, Network, Advanced and Airport and minus out everything under preferred networks. Of course, not everyone will have this option, but if you do, then give it a try.
Sometimes if you have a bunch of networks stored there, the problem can occur. Add a new location and give it any name you want. Again, the problem is so random and the fixes that have worked for some are also very random!

Method 2 — Channel Interference This problem is one of the hardest to detect because it has nothing to do with your computer or hardware.
One way to fix this that I have told my clients is to download this WiFi Scanner app: Method 3 — Router Security Settings Another big one was security settings on the router. Method 5 — Faulty Wireless Card Though not as common, you may simply have a faulty wireless card on your Mac. Method 5 — Delete plist Files Some have had luck with deleting some of the preference files related to Airport and Networking.

Very ambiugous instrucitons. I rarely comment on articles, but I will here to warn you of a problem with your instructins. Got to step 2 on the remove and re-add wifi. Removed wifi service, went to re-add, but your instructions are unclear, guessed that I was to add the name of my wifi service and now I have a status message that says my wifi service does not have an ip address and cannot connect to the internet.
Check Your Mac’s WiFi Settings
Nor can my mac find the network. Luckily i have clicked the revert button and undone these poor instructions. Please review these instructions for users of os Lion for mbp version They are NOT helpful. I have the same problem When deleted the wifi could not connect it again saying no IP address for the wifi? Thank you Chris. I was trapped on an overnight layover in Narita Japan. Nearly six hours were spent googling and trying suggestions found with my iPhone. But it was your great advice to remove and re-add the WiFi service that got my laptop back on the Internet during the rest of my 19 hour layover.
I literally searched the internet for over an hour to figure out the problem with my mac. This website is the best!

UKH Forums - "Your network configuration has changed" Help!
Thank you so much!!! Thanks, just upgraded to Mountain Lion from Lion and the Wifi dropouts started immediately. I did everything listed above and now the connection is solid — Over 5 hours so far with no dropouts. Thanks for posting this information. Thank you soooooo much! Great article. Eventually I got it to work by going into the router admin address http: Somehow that worked. I was about to throw this mac out the window.
This is an excellent article, covers everything you need to know in a simple, concise manner. Get yourself a wifi analyser app on your phone, look to see which channel is the least crowded, and set your wifi router to that channel. This is the only solution that worked for me. Wow… Your advice and tips actually worked.
Wish you could help me set up my idiot stick speakers now. If only! Keep up the good work! I got somewhat worries there. This solved it for me: My knowledge of computer is limited.
