Wifi DHCP and other Config on 5G Home Internet

@webbhead , you are partially correct. My Eero 6+ provides the IP addresses and wifi internet access for all of my clients (thermostats, frig, tablets, phones, etc.). The TM gateway provides internet access to my eero. The TM gateway is plugged into the WAN port of the Eero main unit (I do have a mesh system).

I logged into my Eero app, went to the network settings, and switched it to "bridge mode." I rebooted both when I started the process - TM gateway first, then the Eero wifi router. All devices (unless manually IP'ed) receive their IP from the TM gateway DHCP server. I used the HINT Control app to turn off any SSID/beacon from the TM gateway.  

I hope this helps.
