The route shows how the WAN port is connected to the unconnected network cable

1. There are two ways to network cables, one is the cross line, the other is the parallel (straight-through) line 2, the practice of the cross line is: one end adopts the 568A standard, the other end adopts the 568B standard 3, and the parallel (straight-through) line is the practice of the 568A standard or 568B standard at both ends, (the practice of the 568B parallel (straight-through) line is generally used).

4. Two standards for network cables:

568A Standard: White-Green, Green, White-Orange, Blue, White-Blue, Orange, White-Brown, Brown 568B Standard: White-Orange, Orange, White-Green, Blue, White-Blue, Green, White-Brown, Brown.

5. The above two kinds of cross-wires and straight-connected wires are used in these four cores (white-green, green, white-orange, orange and two pairs of stranded wires).

Causes: 1. The WAN port of the router is not connected to the network cable or the network cable is not connected properly. 2. The WAN port rate of the router is faulty.

3. Network cable problems. In this case, you can consider changing the network cable connected to the router's WAN interface. Workaround:

1. Check whether the network cable of the router is connected correctly, 2. Check whether the network cable is connected and check whether the WAN light is on: AIf the WAN light is on:

The WAN connection status keeps showing that it is not connected, log in to the router interface, and click "Advanced Settings" - "System Tools" - Factory Reset. b.If the WAN light doesn't come on:

Reconnect the WAN interface network cable connected to the router, and then check whether the WAN light is on, if it is on, click "Advanced Settings" - "System Status" on the router interface, and refresh the interface where the WAN is not connected; If the light still does not turn on, please test whether there is a problem with the WAN interface of the router, if there is no problem with the interface, click "Advanced Settings" - "WAN Port Rate Control" on the setting interface of the router to change the WAN port rate to 10M full duplex or upgrade the corresponding upgrade version, if not, it is recommended to replace the network cable connected to the WAN port of the router. How to test whether there is a problem with the WAN interface of the router: a network cable, one end is connected to the WAN interface, and the other end is connected to any interface of the LAN port, check whether the WAN light is on, if it is on, it means that the router interface is fine; If the light is still on, it proves that it is a problem with the WAN interface of the router, and you can take it to detect or replace it.

Prompt WAN port is not connected, then check whether the network cable of this port of the route is plugged in, whether the network cable is connected, first plug the network cable plugged in the port of the router directly into the computer to try whether it can go to the Internet, you can change a network cable connected to the WAN port to try it, if the network is normal, then set the route to the Internet according to the Internet mode, <>

Factory reset your wireless router and set it up again. Do you need to dial up the broadband cat to connect to the wireless router, you do this: plug in the wireless router, don't answer the cat first, reset the wireless router (factory reset), connect the computer to any LAN port of the wireless router, enter the router gateway address in the browser address bar (there is on the label behind the router), enter the settings page, and set it according to the PPPoe (ADSL virtual dialing) method.

Then set the SSID, encryption method, and password. Save, restart. After setting, connect the network cable from the cat LAN port to the WAN port of the wireless router.
