WiFi works but a wired device does not. Three tests that isolate the cable, the device or the router.

Overview

If WiFi works and ethernet does not, the satellite link is fine. The fault is in the cable, the device, or the Starlink hardware. These three tests tell you which, in order.

Steps

1. Try a different ethernet cable

If a different cable works, the original cable was the problem. Done.

2. Try a different device with the working cable

If only one device fails, the fault is that device’s ethernet port. Contact its manufacturer.

3. If no device works

The Starlink ethernet adapter or the Starlink router is at fault.
