I need some help. I got my 5 today. When I came home I started backing up my 4s to the cloud. While this was going I turned on the 5 and put in my wifi password. I then decided to wait until the backup was done before I went any further with my 5. This must have been a bad idea as neither my iPad or my 4s will connect to wifi now, no matter what I do. Anyone able to tell me what this screwed up and how to fix it?
