I bought a Turbo Droid about 3 weeks ago. I believe I'm running 4.0. It's the one before Lollipop. I go into Settings/Wi-Fi. I have a choice of about 10 different providers. It shows their signal strength and then a padlock on top of it. The one I'm using has no padlock. That one is "xinfinitywifi". It has about the worst reception of all of them. I want to change to another one; namely "NETGEAR46". When I select this one, it shifts to another window. They want the password. My question is, "how do I find the password, and is that all I need to open that provider"? Thank You in advance.
