C6300 stops broadcasting, resets to channel 0 with Samsung Galaxy Book 12

Thanks, I managed to resolve the issue, but I'm not sure exactly what the solution was. I took the new device (Galaxy Book) to another location and updated all of the software/drivers. When I brought it back home, I was able to connect to the network. Then the C6300 evidenced a new problem: it was broadcasting and I could connect to the wifi, but there was no access to the internet (couldn't even get to the C6300 admin page with an ethernet cable connected directly). Called Time Warner Cable (Spectrum), went through a few things, and ultimately did a hard reset. I had been avoiding that because I didn't want to set up the networks again. But I did, and so far, so good. I'm on 36+ hours of stable connections/internet. Hoping that's the end of it.
