iMac connection trouble - help!

Hi there,

I bought my 24" iMac last week, got it set up and connected to my WiFi and all has been well.
Tonight, however, it spontaneously disconnected from the wireless router and refused to reconnect. My old laptop and iPod Touch both remain connected.
I have rebooted both the iMac and the router - this hasn't helped.
I have de-activated and re-activated airport.
In the bar at the top, when I click the airport symbol there is a tick next to my network as if I am connected, but when I try to open Safari I'm informed that I'm not connected.
I ran network diagnostics, and typed in the password for my network (double-checked). A pop-up appeared: "Your network configuration has changed. Click OK to proceed to the next step."
On clicking OK I got the following error message: Unable to join AirPort wireless network: "This computer was unable to join the AirPort Network you selected. You may ahve entered an incorrect password or network name, chosen the wrong type of wireless security, or you may be out of range of the base station. To change your previous choices click Go Back".
No error code given.

This occured spontaneously without me moving the router/comouter, changing any settings or passwords...

Any bright ideas? Any help much appreciated!

Irritatingly, connecting with ethernet is not an option right now... my router's by the front door, so would have to move the mac and lie on the doormat to use it, hehe. For now, I'm using my old windows laptop for connection.

I guess if i need to connect the mac to sort it out, then doormat it is.... but for now i'll put up with windows!
 
same problem...

very strange- we have had the same problem with a new iMac- suddenly stopped connecting to the internet around a week ago- and we have just found some time to try and sort this out.

Same again, appears connected to airport but won't connected to internet. Performed network diagnostic checks and identical error came up.

So found it interesting that someone else has had a similar problem!

Have you had any joy in fixing this?
 
I had a problem similar to this, but I was connected directly to my modem via ethernet. The friendly folks over at the Apple Discussion board helped solved my problem, which you can read here.
 
same trouble

the problem ceases if u reset the modem ( pull out the power cable and connect it back after about 10 seconds ). sometimes you have to do it repeatedly before it connects though. sometimes when i find my network name in the wireless networks window and type is my password, i get a msg saying connection timeout. n then i gotta restart the modem again. its the same trouble everytime i switch on my comp. is there any way to sort this out for good?
