Yay! Got it to work! I took out the battery and left it without the battery for a couple hours(I was going to send it back, so I put everything in the same way I got it). Then I wanted to try one last time, and when I tried, it worked instantly... the weirdest thing is that I had aleady tried taking the battery out 2 times before and it didnt work.

Nokiafarce, Iv tried that. Id didnt work. I even tried at a friends house and at burger king. But thanks for the help

I just hope it doesnt go back to being weird. I hardly want to wait for another n900! Now I can finally play with it ^^

Thanks to everyone who helped me in this thread

Edit: It wasnt the battery.. it was n900 wouldnt connect to WPA-1 (Dont remember the exact name), but it connects to WPA2. I forgot that I changed my security to WPA Auto (I think thats what its called). So I tried to check to be sure, and it does connect to WPA2 but not normal WPA. But why didnt it work at burger king? ><
