I have a 1400 sq ft 2 level townhome. I have had 2 Nest Wifi Routers hooked up, one upstairs and one downstairs. It has worked well but I wanted to add a third. So I hooked it up and was literally 7 feet, in view from the main point and it was saying that the new Nest Wifi point had a weak signal. I moved it all over and nothing. Tried resetting the network, unplugging everything, and it wont go off of weak signal.
