Help Please help: Cannot connect to WiFi


Hi, this is my first post :)

I use to be able to connect my Ace to my WiFi but ever since I updated it from 2.3.3 to 2.3.5 I cannot connect to my WiFi.
It asks for the password,which I inputed, then it goes into the authentication and disconnects, then it repeats the authentication process over and over.

I have tried the Factory reset and the 326 one as well and no luck :(
I have also searched all over the forum and still no luck.
Please help me.

Thank you and have a nice day

And on an unrelated matter, anyone know any official,legit roms I can download?Or does it not exist yet? thanks
