Hi  @La_antilla6km,

According to the translation of Google Translate, I think that your question is to add a new extender. If there is any discrepancy, please describe it in English.

You can use two extenders together in a single network. To ensure optimal network quality, it is recommended to connect both extenders directly to the host router's Wi-Fi network instead of connecting one extender to another. Assign a different Wi-Fi name to the first extender so you can separate its Wi-Fi from your router's. The setup process for adding a second extender is the same as for the first one.
If both the router and the extenders support the EasyMesh feature, you can follow the instructions provided in this link: How to add a Range Extender to an EasyMesh Network as a Satellite Device
