To create a comprehensive Home Wi-Fi system offering both excellent network speed and comprehensive wireless coverage, it is common to install more than two Deco Mesh units throughout the house. A recommended approach is to position the main Deco unit in the central area of the house, with satellite Mesh units strategically placed around it. This configuration, known as a star topology, offers various advantages. The primary benefit is that there is only one hop between the main Deco and the satellite units, resulting in minimal speed loss during wireless communication. However, a challenge often arises as the internet modem is typically pre-installed in either the basement or attic. In such scenarios, opting for a daisy chain topology becomes a more practical solution rather than a star topology, such as the following multi-story floor plans:

Then How does the satellite Deco decide to connect which Mesh unit? 

Deco intelligently selects the optimal signal source on its own, taking into consideration not only the signal strength but also the connection rate. This ensures that the satellite Deco units maintain consistent speed and reliable connections. After conducting a comprehensive comparative analysis, the main Deco remains selected by the satellite Deco, guaranteeing a stable and high-performance connection. 

For more details, please refer to Why does the farther satellite Deco always tend to connect to the main Deco?

Is there a way to force the connection If I want to change the current signal source?

Yes! With the recent firmware release, More and more Deco products support customizing Connection Preference which allows user to customize their own network topology based on the actual placement. It gives us three options:
•    Customize the preferred signal source on satellite Deco.
•    Select the preferred connected Deco on mobile clients.
•    Decide whether to connect 2.4Ghz or 5Ghz for mobile clients. 
With a little help from the Connection Preference, the Deco Mesh System could provide every satellite Deco and each client with the expected signal source, then the optimal speed and reliable connection.

3. Can I still select the Connection Preference if some models in the Mesh network do not have this feature?
You are able to customize the preference signal source on the Deco APP as long as the selected satellite Deco Supports Connection Preference. However, selecting the preferred bands and Deco on mobile clients requires support on all Deco units in the Mesh.

4. What if the mobile client does not connect the preferred Deco?
A client device decides whether to roam or not depends on many factors. Please refer to This Link for further explanation.
