Since the ports work for WAN and backhaul but not for client devices, let's troubleshoot to determine if this is a port functionality issue or a configuration problem:

1. Disconnect one of your client devices (such as your Windows 11 PC) from the Deco, and connect it directly to your modem (or another device known to be working) using the same Ethernet cable to confirm whether the PC and Ethernet cable are functioning properly.

2. If the PC still indicates that no Ethernet cable is connected, the issue is likely not with the Deco, but may be related to the PC's Ethernet port or the Ethernet cable itself.

3. Try a different Ethernet cable and verify its functionality by connecting it to another device with a confirmed working Ethernet port.

4. If both the PC and Ethernet cable are confirmed to be working, test the same client device on different Ethernet ports on your Deco units for comparison.

5. Try testing with different satellite Deco units (not just the main one) to see if client devices can connect to their LAN ports.
