How do you hook up to WiFi once you have the WiFi finder app

Yes if that works great if not call a tech support at spectrum

I use the WiFi finder to find the spot, once I find it, I leave the finder, and just connect to it as the normal ones. Each spot has 2 SSID, one is FREE the other one need Spectrum account ID and password. Actually I can't see the difference between those two, so I just connect to the free one so I don't need to input the info.

I'm not sure. I got rid of cable but kept my WiFi/ internet service with Spectrum.
