So i set a password. Called dlink they told me how. changed name, put the security from open or none whatever is was to wap protected , and set security key, n changed 5ghz name and set same security key there. So it should be secure now. I just type the password for people that should be on n it should keep them connected w.O require password each time right. So when i saved it now says protected with wpa/wpa 2 n requires password . The signal on my cell is weak now though, sometimes not picking up connection, we have a extender halfway to router so it shouldn't be weak . But we had it set so device would auto connected to extender , would setting the password change something ? My ps4 is still ok because its on the powerline adapter so technicaly lan,
