Cannot connect to my WiFi: "Saved, secured with WPA /WPA2" I cannot connect to my WiFi at all. I have a Nexus 5 and it has been fine for a long time. All of a sudden, I just cannot connect to my WiFi. I try to connect, and it either says that I am out of range, or that my connection is secure. When I enter my passcode, it just doesn't connect, gives no error or anything. It just keeps saying secure connection. I am on KitKat, the latest version.
I don't know if this is an Android issue, so much as a WiFi problem. A while ago (before I got my Android) I had some issues connecting my computer to my WiFi -- my computer sensed that the network was there, but wouldn't connect. I was advised to reset the network.  


Unplug all parts of the network: router, modem etc.
Hold your breath for ten seconds.
Reconnect everything.
Try connecting to your network again.


This worked for my computer; give it a try for your phone, and tell us what happens.
