I just got Kindle Fire 10. Wouldn’t connect to my ATT wireless network. My Kindle Fire 7 was online. I thought maybe I had too many devices online so I turned off the Fire 7 internet connection. PC is online. Now neither Kindle Fire will connect. Ive tried everything, did all the steps over and over. Still getting rejected for my modem’s password on both Kindles. Can anyone help me? Keep in mind, all my other devices are connected. Includes an iPad.
