How many working modes does the network device have?

2. Routing mode: After the WAN port of the network device is connected to the uplink device, you need to select the correct network mode (such as PPPoE dial-up mode, dynamic IP allocation mode, static IP mode) on the network device management page, and configure the corresponding parameters then you can access the Internet. 
3. Relay mode: The network device bridges the existing wireless signal to expand the coverage of the wireless network, and the user can customize the local wireless network information.
