I have an old PowerBook G4 which I don't use anymore, due to this problem. I used to run Leopard on it, until it crashed, and I downgraded it to 10.3 (i think.) Now, I cannot connect to my wifi connection. It reads it, but when I type in the password, (which I assure you is correct) it says that the password is wrong. And when I put in the Leopard install CD (for my macbook) it can't install Leopard, which is obvious, but I can connect to my wifi. How do i fix this wifi problem? Or something else, is it possible for me to install leopard on a DVD then boot off of the DVD? Thanks!
