I'm having a similar problem. I'm able to connect to the wall charger's broadcast signal and enter all relevant info and commission it to 60 amps, but it continually says "no internet connection". I've tried changing security protocols WPA3, WPA2, ...etc. but it never connects to the internet. I was able to download the latest firmware update locally, then connect to the charger's network and install it, but the wall charger never reaches the internet. Does it even have to? What's the point of it? If I can DL the firmware updates and install them locally, why do I need internet access on my charger?
This whole thing has me confused.
