Question about TP-Link Deco BE25 (1-pack)

To increase the Wi-Fi range, a single Deco BE25 is sufficient as a mesh router if you connect it to your internet provider's router via cable or Wi-Fi - a connection via NFC is not technically intended and not possible as the Deco BE25 does not have an NFC function. For even better coverage, especially in larger flats or houses, you can add additional Deco units via Mesh, which then automatically network with each other. Two routers are therefore not absolutely necessary, but can be expanded if required.
