You could consider having a wired backhaul between the puck instead of wireless mesh. Which means pulling an ethernet cable between all the Nest Wifi pucks. Ethernet can travel over coax (MoCA) or powerline too, if pulling ethernet cables everywhere isn't an option. This would require all Nest Wifi pucks to have ethernet ports though, which the "Nest Wifi add-on point", the one with mic and speaker, does not have.
Recommended setup is to have a unmanaged, "dumb" switch behind the primary/ main Nest Wifi puck, like a Netgear GS108 for instance.
Then connect all other Nest Wifi pucks directly back to this one. Though it might work, it's not recommended to :
- Daisy chain the pucks, as it would create a single point of failure, and might affect performance.
- Mix wired and wireless backhaul, because mesh (802.11s) does not travel over ethernet, which could cause strange issues because of loops in the network.

If wired backhaul is not an option, it's good to know that the Nest Wifi router has better wireless range and performance than the Nest Wifi add-on point. One can create a wireless mesh network consisting of only Nest Wifi routers. More about the hardware specifications here:

It could also be worth waiting for the newly announced, but not yet released, Nest Wifi Pro. The biggest caveat there is that it is not backward compatible with any previous Google Wifi or Nest Wifi pucks. But wireless mesh performance should be greatly improved with Wi-Fi 6E (802.11AX) and 6Ghz. More info:
