This has been happening for a while. I couldn't connect to my home wifi. Every time I tried to connect it keep saying the wifi is not in range, not showing me the network even if it is online, and when I did see the network and tried to connect it, it say "Authenticating fail". I can connect to my school wifi. This started to happen after the software get updated. I've reset my kindle several times and still not working. Can anyone help me?
