It looks like Deco is not properly connected.
Deco xe75 pro won't connect on 30 foot ethernet cable, cable continuously Passes on the cable tester, no problem connecting on shorter ethernet cables, ( I have tried several and no problems. I have a Starlink gen 2 satellite and also bought the ethernet adapter to expand whole house. I want to keep the Starlink router also. Why is Deco not connecting on the longer cable??? Keeps saying ( It looks like Deco is not properly connected. Not happy with this product so far, might have been better off buying an other Starlink wireless router. Open to suggestions, I see where others are getting the same message I am getting.
