Airport/Airport Extreme connection issues

[EarthDawn]

OK... tonight it is driving us nuts !

Here are a couple of screen shots of the failures.

I cant get on my network as it keeps saying password failed etc. 3 iphones and 2 ATV's and the ipad are connecting with no problems at all.

I was able to link to my neighbors wifi that has no password though

And... it's a 1 month old MacBook Pro 13" and a pre 09' White Macbook

AND the iMac in the bedroom is working on my wifi fine as well.... Odd

My 13" MBP is/has been doing the same thing. I keep having to rejoin the entire wireless network everyday.

Well my accepts the password and everything but it keeps dropping my laptop and I'll have to rejoin.

Same thing keeps happening to me on my 13" MBP. I only got this computer last week (I'd had the same problem on my 2007 Macbook and hoped to problem would be sorted). It keeps on telling me in airport that theres either no IP or a self assigned IP, but sometimes it just connects but the connection is quite slow. This is very annoying, indeed.
