No more auto connect

I’ve been all over trying to find out wtf is wrong with my automatic connect to the internet. I got a nice new case and figured it was something I changed, then it dawned on me Charter/Spectrum changed my router to a Sagemcom and I installed a Netgear A6100 WiFi Adapter. Now every time I boot I have to manually choose the ISP and enter the password. A real pain. Anyone have a clue to auto-connect?
