The telecom cat and the switch are connected to the laptop with a network cable, but the switch can't go to the oil leakage and room network cable. Is there a great god coach?
First of all, confirm whether the network cable connector is normal. The switch can connect the laptop to the Internet through the network cable, indicating that the external network is normal. Routers and switches cannot access the Internet. It is very likely that the cable connector is wrong. You can compare it with the laptop cable.
