Hello, first post here.

This is the 2nd time I had the same problem. I changed the name of my home network to fix it last time.

I have been successfully connected to my home network for several months. Just today, I have no bars on my airport status. None of my settings have changed on my network. In "Network Diagnostics", all lights are red. When I click on my airport icon, several networks are listed. Many of which are my neighbors (with 1 or no bars), and also my home network is listed (full bars). When I click to connect, it "thinks" for a few seconds and pops up an error message. "Unable to connect to the network <my network>. Please try again."

My network security is WPA2 Personal. When I try to re-enter the password in my network settings, sometimes a new network is listed in my "prefered network" list. <my network> WPA2 Enterprise, along with WPA2 Personal.

My fiance's iBook does not have any problems. Every now and then, she has to re-enter the password, but never any serious problems.

Please help!

Unfortunately this occurs sometimes. I have no idea why it happens, (it has also happened to me several times) but I do know how to cure it until the next time it happens.

Before you start the procedure below, hook an ethernet cable from your router to the computer. I'm assuming here that you know how to access your router and make changes. If you don't know how, break out your manual and learn. OK. Reset your router to factory default. That will clear all SSIDs, DNS settings, security and passwords. Be sure you are able to reenter all settings before resetting. (write them down)

Alright, now we have to completely remove the old connection. Here's how:

The first thing to do is open System Preferences, Network, and click on "Airport". Click on "Advanced". Click the Airport tab. Under Preferred Networks, remove your connection SSID (name) by pressing the minus button below and then select "apply". Close System Preferences.

Use the Finder and navigate to: /Library/Preferences/SystemConfiguration/

Move the following two files to your desktop:

com.apple.airport.preferences.plist, com.apple.network.identification.plist

Close the Finder and go to Applications, Utilities, Keychain Access.app. Run the Keychain Access application. Look for your "Airport Network Password" and delete it. Do not mess with any other passwords or items in the keychain.

Now you can add your connection back. For "Location" you can either use the "Automatic" setting or another of your choice. (I use "home")

Make sure your router is correctly setup with the SSID broadcast on and security set back to WPA2 with whatever password you selected. You should be able to connect now.

If you need any more help, respond back here or PM to me.

By the way, the method I described above is exactly the same as what Apple recommends.

Regards.

Hello! I have a problem with my mac.
I feel like i´ve tried all!
Could it be something wrong with the router? I live in a dorm in Norway, and my mac is bought in USA. Everywhere else, the airport-dots is full, this is the only place it doesnt work. It is two routers here, and both of them is "dead". Is seems like some places in the dorm, the network is working just a little. The two other guys with mac here, doesnt have a problem with it. Do you guys have any clues? Im driving nuts!

Hello!
The other guys are connected to the same network as im trying to connect to.
The router is Linksys (some code i dont remember). The funny thing is yesterday I discovered that in a few places, the airport is fine, but in most places id doesnt work at all. I really dont know what to do. Is there some routers that doesnt cooperate with mac. And why does the other macs work? Could it be because mine is from USA? Argh..

Where you bought it doesn't matter except with power conversion. I'd see if there's somewhere you can plug in ethernet or get to one of the good spots and download the latest updates for Airport and that your settings match these other guys.
