how do I change the wi-fi password?

[AC Question]

I am staying with my sister and was recently in the hospital. They put in the hospital password and we do not know how to change the password to get my tablet to connect to her wifi. Also, how do I reboot the kindle?

When you turn on WiFi from inside your settings, you should have an option to look for available WiFi devices. If the device has been connected to that router, it should remember and auto login once near it....
