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
Locations: Automatic
Highlight Airport
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.

Jun 18, 2013 3:33 AM in response to APZby ah_help,Hi, I have this problem too and Ive tried all of the solutions out there on the web.
I have a mac pro connected and also a pc connected with no problems
Reset PRam,
Reset SMC
Deleted airport connection and re installed it
Deleted all of the DNS numbers (not that I know what they are) in network/advanced etc
Had the airport section of systempreferences/network say everything from "on" but no green light to "no ip adress" etc etc
Restarted the macbook many many.........many times
Restarted the router an equal amount to the restarts ive done
Obviously ive gone round the bend putting the password in approximately 1.2 million times just in case my eyes were deceiing me on the screen and my fat fingers had typed in incorrectly etc etc etc etc.
Please help if anybody can as this seems to be a huge problem and no one has a difinitive solution as some things ahve worked for some people and not others......unfortunately nothing has worked for me.......
Help will be greatly appreciated and a pack of chocolate chip cookies to whoever can solve this beast of a problem.
Many thanks......
