Hello @Christian-W ,

Thanks for contacting our community.

Deco and Archer routers currently use two different Mesh protocols.

If you already have an Archer BE800 in use and the Deco unit is newly purchased, it is recommended that you return the Deco unit and replace it with a device that also supports EasyMesh. Below is a list of EasyMesh-compatible devices; you can filter by option in the left-hand menu to select the product that best suits your needs.

Best Regards.

Hi @Christian-W ,

While TP-Link's Deco, Archer Router, and Omada EAP all support Mesh functionality individually, they are not designed to work together to form a single Mesh network. These product lines, although under the same brand (TP-Link), differ in their technology and software, preventing them from interoperating in a unified Mesh network, you may still be able to use them together, but they won’t be able to form a single, unified Mesh network. In other term, if you use an Archer Router and a Deco system together, there won’t be any seamless roaming between the Router and the Deco system.

For more details, please refer to Can Deco Mesh, OneMesh, EasyMesh and Omada Mesh products work together?

If you need help identifying compatible models or planning a mesh setup, please let us know—we're here to help.

In addition, we generally advise users to purchase products locally rather than from other regions, as this can affect the return process if products are incompatible and subsequent warranty service.
