The what's my IP address is the IP address provided by your Internet Service Provider for their modem before it translates to your local IP address of your router. If your modem and router are a combined unit you can try http://192.168.1.0
The encryption you select on the Guru must be the exact encryption type selected in the router. I think that is where your connection issue lies at the moment. If that password works in other devices it should also work in the Guru.
Maybe you can check your IPhone or Xbox and see what encryption mode you selected with them and then set the Guru accordingly.
