I do. the 4S can not connect to the Wifi even with the correct password. When I enter the Wifi password on the 4S, it said invalid password, even when I know I type the password correctly and all my other devices are (iPhone 5, Blackberry, laptops) using the same password and can connect to the wifi.
I reset the router password, reset network settings on the 4S and still can not connect to the Wifi.
