Tesla Motors Club

While waiting for the Tesla Wall Connector to come back in stock, found a used one at a good price and bought it. (not sure which generation- it's glossy black and NOT the signature version) It's in great condition, but the problem is the original owner lost the quick start guide and never used the wifi feature. As a result, the wifi password is the original default password, and is unknown. Does each unit have a unique default password?

Is there a way to reset the unit to factory settings, and regenerate a default password?

Any other advice?

Thanks...
