I have just got an Iphone and when trying to connect to the Internet at home it can see my Router but when I input the Password it wont allow me to connect to it. I have a Zyxel P-660HW Router and have other Computers connected wirelessly no problem. I have tried going in and changing the Key in the Router then it encryptes the word so I have tried both in the Iphone the word and the encryption and still nothing works. Hope someone can help as getting very frustrated and dont really want to buy a new router.
