Google Nest Wifi Netgear switch - No Internet

[Bzacks]

I am having trouble setting up Google Nest Wi-Fi that is connected to a Netgear GS305P switch. I got through the setup, but the Google Nest Wi-Fi indicates no Internet connection. My network configuration is as follows:  Xfinity Modem/Router/ Switch combo – connected to the Xfinity switch is a Reolink DVR/Switch with several IP cameras connected to this.  I also have the Netgear switch connect to the Xfinity switch that also has several IP cameras connected to.  This all appears to work fine.  I am attempting to connect the Google Nest Wi-Fi to the Netgear switch to provide Wi-Fi, but the Google Nest Wi-Fi indicates no internet connection.  I have the Google Nest Wi-Fi Internet port connected to the Netgear connected to one of the switch ports.   When I connect the Google Nest Wi-Fi directly into the Xfinity box switch the internet works.  Any help resolving this would be greatly appreciated.

Although that Netgear switch is an unmanaged one, it's possible it has features enabled which is preventing Nest Wifi from working properly. I'd suggest checking it's manual or online documentation and disable Spanning Tree Protocol (STP) and forward Bridge Protocol Data Units (BPDUs) when STP is disabled.

It's also worth bearing in mind you have have created two networks with your setup. Devices behind your Xfinity combo box and devices behind your Nest Wifi router may not be able to communicate with each other. It's for this reason we recommend connecting all your devices behind Nest Wifi to avoid issues.

Just to add to what @David_K said: I can't see any problem with the switch, except from PoE it does not seem to have features my GS108 doesn't have.

And here's a diagram on how it should be wired:

Thank you for providing this information.  The google Wi-Fi router (I only have one) is connected to a Netgear POE switch in another building (Garage) to provide Wi-Fi to that area.  This Netgear POE switch is connected to the Xfinity Modem/Router/Switch.  Given the distance (175FT underground) and only one cable available, I don’t see a way to place the Google Wi-Fi router between the Xfinity and the Netgear switch?
