3. If it is DHCP, there is no need to make other settings, and the router will automatically obtain the corresponding network settings. If you choose PPPoE, you need to fill in the correct user name and password, which are provided by network service providers, such as China Telecom. If you forget your password, you can call 10000 for manual consultation.

The most important thing is to turn on the DHCP function, so as to ensure that the router can assign IP addresses to devices when they access LAN ports or connect to wifi. The IP address range allocated by DHCP should be in the same network segment as the IP address of the router, such as192.168.1.x.
5. Finally, check the security settings of the router. Check whether some security policies that restrict MAC or IP address connections or corresponding speed-limiting policies are turned on. If so, please turn it off, otherwise only devices with specific MAC or IP addresses can connect.
