Greeting,

In my house, there currently 2 Wifi devices connected in mesh.

First floor is OK, more open space, not reaching the kitchen but we don't mind that.

2nd floor however has more walls,and we found low/null signals on outreaches of the rooms.

So what solution do I have for 2nd floor? What things do I need to look at in specifications of wifi devices that would be able to reach every part of the 2nd floor?
