Transmit power is not adjustable on Google/Nest WiFi products. In relative terms, the transmit power is quite low to start with, though. Reducing the transmit power can have counterintuitive effects as well. For example, reducing the transmit power may require sending data at a lower speed, meaning the transmitter may actually be on longer than it would be at the higher power. Since this product is intended for typical consumer use, it's unlikely they will expose this as a configurable parameter due to the increased likelihood that it will result in poor performance and unexpected behavior.
I just wanted to jump in real fast to see if you saw olavrb's and MichaelP's replies and to see if you still needed some help on this or if you were able to get it sorted out. If you are still needing some help, just let us know and we'll be happy to continue helping.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
