What should I do if I cannot access the Internet after the network device is set up?

1. Please make sure that the network cable of the network device is connected correctly. Pay special attention to the different services of the LAN port of some uplink devices. If you cannot access the internet, you can try to connect the network cable to other LAN ports of the uplink device.
2. Please check whether the selected Internet access method conforms to the actual line environment and whether the filled Internet access parameters are correct during the network device setting process.
