My
mesh in on 1st floor. You need to connect Ethernet cable for 1st mesh from main
router. After if you add more mesh nodes, they connect wirelessly. But my home is duplex, I don’t want to connect it with wire, so we tried wirelessly and it was successful. My plan is Silver 150 Mbps. On Ground floor I get 145 Mbps, on 1st floor with mesh I get 130 Mbps and on the terrace I get 20-30 Mbps.
yes both 5 and 2.5 GHz
