I have fairly limited networking knowledge.</P><P>There is a clash between the Google Mesh router DHCP and the Zyxel modem DHCP as occasionally reported by Fing. On the Nest I have gone through the process of setting up a static WAN IP, setting a fixed DHCP IP Address pool of 192.168.86.2. BUT, when trying to add a DHCP reservation, the list of MAC addresses does not include the 10.0.0.1 or 10.0.0.2 routers. What must I do now?</P><P>Please help!
