I'm having my system installed next Friday; I'm having two powerwall 2's installed. I've read that the Gateway needs an internet connection.
It's my understanding it can use WiFi to connect to my home router or a hard line. I have the option to run a hard line cat 6 to where the gateway will be installed. Is there any advantage to a hard line? Disadvantage to Wifi? If your wifi password changes or you get a new router, how do you re-configure your gateway wifi connection/password?
