Wired devices can't see devices connected to Nest WiFi

[thracian]

I have a AT&T BGW320 gateway. I just got my Google Nest Pro WiFi 6 3-pack and so far everything is working great except the following issue. My laptop is connected to the AT&T gateway usually during the day with a wired Ethernet connection. On the gateway, I have enabled IP Passthrough to Google WiFi and disabled the gateway native WiFi. However, I can't connect from my laptop to any devices that are on the Google WiFi network, such as printers and other laptops. It's like the wired connection devices are on a different network than the WiFi devices.

How can resolve this?

Hello @thracian 

It's like the the wired connection devices are on a different network because they are, in fact, on a different network. The primary Nest WiFi Pro unit is a router+firewall that creates a new "inner" network, separate from the "outer" network created by your AT&T gateway. Connectivity between these two networks is limited by the firewall feature. The solution is to build your wired network from the LAN Ethernet port on that primary Nest WiFi Pro unit, leaving it as the only thing directly connected to your AT&T gateway. You can use an inexpensive, unmanaged Ethernet switch to make more ports available and build out as big a wired network from there as you need.

Never mind. Indeed, Nest Wifi creates its own network on 192.168.86.x. The solution was to change the Nest WiFi advanced network settings and put it on the gateway segment as explained here. Make sure that the DHCP range doesn't overlap with your gateway DHCP range.

Hey thracian,

It looks like you were able to get this worked out. I'm happy to see a resolution found. Before I mark this as resolved, I just wanted to check in and see if you had any other questions or needs.

Thanks,
Jeff

Well, it worked yesterday but not today. I must have connected the wired device to both LAN and Nest WiFi. Any idea why I can't see WiFi devices if they share the same network.
