Wi-Fi passwords are forgotten My nexus 4 is not storing new Wi-Fi passwords. Each time I want to connect to a previous connected Wi-Fi I have to re-enter the password.

I found that in Settings &gt; Backup &amp; Restore everything is checked but Backup account - No account is currently storing backed up data is in gray and i can't do anything about it.
In Settings &gt; accounts &gt; google i have everything sync but Movies &amp; TV and photos.

I'm running kit Kat, not rooted.
Any help will be appreciated
Try deleting (forgetting) the wireless connection first.  Sometimes security information (WPA/WPA2) related to the connection is cached and is no longer relevant.  When the security information doesn't match, the connection can be shaky.

If this is a pervasive issue (all wireless connections) delete (forget) all wireless connections, and open the app in app manager and delete all cached data.
