It's this
https://www.bestbuy.com/site/google-wifi-mesh-rout...Connecting to some devices and not others, idk what's wrong with it, Google couldn't troubleshoot it without access to the modem which I don't have because of the way the internet in my apt complex is set up. Might be an easy fix, don't really want to deal with it though.
It's 10 bucks + shipping (almost certainly under $10)
Selling as-is, it might work perfect for you as soon as you get it, but don't expect it to. Comes with the original box and cords.
