I'm not familiar with Powerwall, but I do use a Pi3 as a WiFi router very succesfully on my boat.
I have an external antenna that picks up free WiFi signals from wherever I am at the time and that is shared, using the internal WiFi adapter.
Works great.
What OS are you using?
Do you have the Pi in a metal case? That will massively weaken the signal.
Are you using 2.4Ghz? the 3 doesn't have 5ghz support.
How are you setting it up?
