When Deco works in the AP mode, it supports wireless backhaul and can build a mesh network.

The switch off the unwanted WIFI band feature still available when Deco works in the AP mode, and the Deco M4 support this feature too.

Hello, the issue you are asking is different from Miguel_S', I will try to explain it to you:

There is currently no option on the Deco app to force connect to a particular Deco yet. Theoretically, the device will select and connect to the Wi-Fi network with better performance automatically. In your case, the 3rd Deco unit prefer to connect to the further main Deco automatically based on the signal strength, it seems that the signal that the third Deco get from the main one does not reach the threshold value. You may try to relocate all the three Deco units and try to find a more proper location for them.

BTW, we have reported this request to our R&D team that allow the administrator to manually select which Deco source they want to connect, and this option will be available in the future firmware update. We cannot give you an ETA at this moment, and we hope you could pay attention to the Deco app for the new firmware release yourself.

Nice day.

Please pay attention to the Deco app for any future firmware updates. Good day.
