Just because it's a 'higher quality cable' does not mean the cable isn't the cause of the fault.
If it connects fine via wifi, but not via cable, then that narrows down the potential causes of the fault. Test the following to narrow it down further:
1. Test a different network cable.
2. If it's still not working with a different cable, test using a different port on the router.
3. If you still have no wired connection, test with a different router if possible.
If it's not connecting after each of those, it's possible the ethernet port in your console is damaged/faulty.
