Can't set custom LAN IP or DHCP range

[igiman]

I cannot change the router IP or DHCP range to be assigned. Always reverts to the preset one 192.168.86.1....

Hello @igiman 

Often, this happens when trying to set the LAN IP or DHCP range to invalid values. For example, since the primary Nest WiFi Pro unit is a router+firewall that is creating a new "inner" network using network address translation (NAT), the LAN IP address cannot be in the same network as the "outer" network.

I found out the reason - the guest wifi was on. Once I turned it off, the change of range and IP went through.
