I’m glad this worked for you. I had the exact same experience with my Generac generator when connecting to Wi-Fi, so I know some hardware has issues between 5-2.4 GHz. The wall charger is no different.
Regarding your WiFi experience, I created an additional network “guest” type account and gave it a simple password. Make sure you only use the “Guest Network “ for the charger. This should elevate your problem, and you won’t have to change any other of your tech to a different password.
