Why I Must Type Password Every Time To Reconnect To Home Wi-Fi Hotspot I have recently started getting dialog popping up asking to enter password every time I connect to my home Wi-Fi hotspot:



This dialog always pops up when you connect to hotspot for the first time and then it memorizes password so you don't have to type again when reconnecting. Until now, reconnection was automatic. A couple of things to suspect might be recent upgrades from 4.3 to 4.2.2 and a week earlier to 4.4.4

In addition I recall that I accidentally turned off Wi-Fi settings icon from appearing in Android's task manager which was before final upgrade if that helps.

Anyone knows what can be the cause? I have LG Nexus 4 E960
Here is the solution which worked for my rooted Nexus 5 (Android 5.0.1)

make a backup of wpa_suppliciant.conf file and DHCP folder. Just in case.


Copy wpa_suppliciant.conf file from /data/misc/wifi/ to your PC
Open with any text editor (I used wordpad) and delete all entries with you problematic wifi name on it.
Choose one of the Wifi in the list which you remember has worked before and change SSID and passkey according to you router. Press SAVE.
Copy/replace this modified file into /data/misc/wifi
Delete DHCP folder in /data/misc/
Reboot your phone.
Your phone should now connect to your new wifi :)
