How to Extend Google Nest Wifi range to 50m

juliusg05

I have the Google Nest Wifi System and I want to extend the Wifi Range to my seaboard which is around 40 meters from my house. I have a second access point in the seaboard but the connection does not reach it. Any tips on how to extend the connection?

A 40 m LAN cable

Is it on the same electricity circuit?

If so I would ditch the WiFi system and plug in some powerline adapters.

I have Google NEST WIFI with 8 points in total and it easily covers my whole house, the very end of my back garden (100 ft) and most of the park outside the front of my house.  Well in excess of 40 m total.  Just put another hub part way out to the seaboard.

By the way, what is a "seaboard"?

@The_Fat_Controller I am unable to dig a 40m LAN cable to the seaboard.
