Local IP network changed to 192.168.85.0/24 (Google Wifi)

This happens when you set up a new and separate Google Wifi network connected downstream from an existing Google Wifi network, or when you connect a Google Wifi point to any third-party router that gives out DHCP addresses in the 192.168.86.0/24 IP network range. Both of these scenarios will change your default Google Wifi point’s local IP network range to 192.168.85.0/24.

This happens because your WAN port needs a different IP address from your LAN subnet.

What’s the difference between WAN and LAN?

Change local IP network back to 192.168.86.0/24

To switch the network back to 192.168.86.0/24, follow these steps:

1. Open the Google Home app .
2. Tap Favorites   Wifi   Settings   Advanced Networking. 
3. Tap LAN.
4. Change the “DHCP Address Pool” to the range you want, and tap Save. Example: 192.168.86.20 to 192.168.86.250 is the default range.
5. Go back to Wi-Fi   Settings   Restart network. This will force reconnection of the clients and new IP addresses to be issued to each of them.

 

Note: If you only change the WAN IP address or disconnect from the “upstream” Wifi point (the one between your modem and second Wifi point), this will not automatically change the local network back to 192.168.86.0/24.
