If you want to use any GOOGLE Nest products, like the Google Nest Protect Smoke and CO2 detector or a Google Nest Hub, in your local TP-LINK Omada network then you’ll have to make some adjustments to your network settings to avoid connection issues.
Before making the adjustments below, all my Google Nest products were having problems to keep a stable wireless connection, even when the devices were only a few meters (or feet) from the TP-LINK Omada Wireless Access Points. Especially my Google Nest Hub (2nd generation) was having severe problems keeping the connection alive.
Create a seperate 2.4 GHz network for IoT devices and disable Multicast Management
Log in to your TP-LINK Omada network controller.
In the top right corner, select your site.
In the left bottom corner, select Settings.
Under Wireless Networks, select the WLAN option.
Click the Create New Wireless Network button.
Give the new network a name (SSID).
In this example we use GMIoT.
Select only the 2.4 GHz Band, disable the other ones.
Set a save password.
Expand the Multicast/Broadcast Management tab.
Disable all options.
Click the Apply button.
The end result should look like the situation below.
Now install and connect all your Google Nest products to the newly created 2.4 GHz wireless network named GMIoT.
This works very well and solves all connection issues typical to Google products, even when the Google Home or Google Nest apps on your smartphone are connected to the default wireless network, in this example named GMWifi.
Just keep in mind to have both networks in the same VLAN!
