My LG G6 won't stay connected to my OnStar Wi-Fi?

[Android Central Question]

My phone (Verizon) connects to my car Wi-Fi (AT&T) and then disconnects. It does the same thing in my truck (same connection). It worked fine, now it doesn't. I can't figure what to change to fix it. I did get an alert that my connection was being attacked when I was using my OnStar Wi-Fi, but I didn't think that was true. Help.

Welcome to Android Central! Have you already tried forgetting the wi-fi network on the phone, then reconnecting?
