Problem with email??

Hi

Not sure if anyone else is having problems with email on their new iphone, when I had the old one it connected to my home wi-fi no problem. The new phone seems to take hours to connect (which kills the battery). Is there anything anyone can think of to make it quicker??

I didn't reset the wi-fi when I changed the phone over as it seemed to do this automatically from itunes? I shall reset the password, other than that I can't think what to do??

Any ideas?
