I want to add a Google Wifi 4 pack into my basement and I already have Google Wifi 3 pack in the attic working great and that is where my cable modem is. I have a CAT6 cable already ran from the attic to the basement where I expect to install the new Google Wifi 4 pack.
Would I want a switch anywhere or should I just connect the new Google Wifi 4 pack in the basement to the LAN port of my Google Wifi 3 pack router in the attic? I want the same SSID in both and basically end up with seven Google Wifi's on one cable modem all in the same home.
The basement ceiling is practically like a bomb shelter and that's why I ran the CAT6 between the attic and basement so I can have a complete mesh coverage in the basement as the 4-pack system will have easy line-of-sight in a long basement.
Help, I'm getting frustrated trying to figure out how to share my single cable modem via CAT6 between basically three floors; my current Google Wifi 3 pack in the attic is already covering my main floor too, and nothing in the basement.
As long as the pucks are bought for the same region/ country, combining will work.
Setup doc specifically says ( https://support.google.com/googlenest/answer/9548301?hl=en ) :
Best practice for wired backhaul is to use an unmanaged switch, like a Netgear GS108, behind the primary puck, connect all other pucks directly to that switch. Daisy chaining is not recommended, though it should work.
It's also worth noting that the mesh, based on 802.11s, does not travel over ethernet. So any wireless pucks in this nebula of pucks will have to connect wirelessly back to the primary puck. Recommendation: Go either all wired, or all wireless for the backhaul. Use coax (MoCA) or power cord (HomePlug) if neccessary.
