Docking station Ethernet works until monitor wakes

Minimal guidance for messy support realities.

Scenario

A docked workstation loses network connectivity whenever attached monitors wake or change state.

Recommended Resolution Path

  1. Update dock firmware, display drivers, and chipset components together.
  2. Test whether the Ethernet adapter resets under USB-C bandwidth changes.
  3. Compare one dock model against another if you have mixed hardware.
  4. If the issue is reproducible, standardize the known-good dock and cable combination.

Technician Notes

Confirm the result, document the root cause, and record any preventative action worth standardizing.
