Hello @BrunoDBNogueira ,

Welcome to our community.

According to Google Translate, it seems that you want to find a suitable satellite node to expand the network. If there is any discrepancy, please describe it in English.

First , there's an important limitation you should be aware of:

IoT Network Limitation:
Most of TP-Link EasyMesh clients currently do not support extending IoT networks. According to our specifications, EasyMesh only supports extending 2.4G & 5G networks (and 6G on WiFi 7 routers that support it). This means your IoT network will only be available from your main GXE75 router, not from the satellite device.

Ethernet Backhaul Support:
The good news is that TP-Link EasyMesh routers are releasing firmware updates to support Ethernet backhaul, which would allow you to use that physical network point you mentioned. Ethernet backhaul provides a more stable and faster connection between nodes compared to wireless backhaul. You can check which specific models support this feature here: EasyMesh Routers Support Building a EasyMesh Network via Ethernet Backhaul NOW 

Note: Both your main router (GXE75) and the satellite device need to support Ethernet backhaul for this feature to work.

Equipment Compatibility:
For a complete list of EasyMesh-compatible devices that could work with your setup, please refer to: TP-Link EasyMesh Devices for Home.

You can also choose from WiFi routers, Range extenders, or Powerline WiFi adapters that support EasyMesh. Just make sure to verify that both devices support Ethernet backhaul if you want to use that feature.
