Set up the router, if the IP and network gateway of the WAN port are all 0 0 0 0

Kiss. If you unplug the router and connect it directly to the network cable, the broadband connection error 678, but you can access the Internet without connecting, it may be that you already have a router in the previous level of this network cable.

You can follow the settings below.

1. If the IP of your local connection is obtained automatically, you can set the router to a dynamic IP, but in order to prevent a conflict between your router and the higher-level router, please set the IP of the router, which is the LAN port.

2. If your local connection is a fixed IP, then set the IP of the router to a static IP, which is the IP of your local connection, and it is best to clone the MAC address. After setting up the router, set the IP address of the local connection to be automatically obtained. In addition, if your local IP address is in the same address range as the router, you need to set the LAN port of the router to the router.

Good luck with your family.

You can reset your router.

Your broadband can be connected to the WAN port of the router.

Then port 1234 of the router.

Connect any port to your computer, and then enter the router interface to select PPPoE Internet mode.

The next step is to enter your broadband and password correctly.

If it doesn't work, you can choose "Network Parameters" - MAC address cloning to give it a try. Hope it helps.

First of all, you need to figure out the access mode of your WAN port, whether it is ADSL, or fixed IP, you need to ask your operator, and then get the corresponding configuration information, if it is ADSL access, the WAN port is set to PPOE, and the broadband is input in, if it is a static IP, you must put the corresponding IP

Gateway, subnet mask, DNS

Fill in the information.

You can go online without a broadband connection, which means that it is a fixed IP or an automatic way to get an IP to go online, you can't use PPPOE dial-up when setting up a router, you can try it with the method of automatically obtaining an IP, if not, you need to find an Internet IP, set up a router with a fixed IP, it should be noted that the network segments of WAN and LAN cannot be the same, and they should be in different network segments.

The IP address of the router WAN port is caused by a setting error, and the solution is as follows:

1. Open the webpage and enter ** to enter the home page of the router and log in.

2. Click Network Parameters and select WAN port settings.

3. Select PPPoe as Type, select Auto Connection, Enter and Password.

4. Click Auto Select Dial Mode, disable the second connection, and click Auto Connect to check whether it is connected.

The WAN port of the router is set to a dynamic IP, but no valid IP address is obtained from the higher-level gateway, which is generally caused by the mismatch between the settings of the cat and the router in the family.

1. There are two ways to cooperate with the router WAN port and the cat:

When the modem is set to bridge mode, the WAN port of the router is set to PPPoE dial-up.

When the modem is set to routing mode, the modem must set dialing, and other devices in the network are not allowed to dial again.

2. Coordination of the relationship between superiors and subordinates of DHCP services.

In the modem + routing + user mode, the LAN port of the modem is the upper level of the router WAN port, and the LAN port of the router is the upper level of each user.

If the DHCP service is disabled by the superior, the subordinate must set the IP address to a fixed IP address, and the IP network segment must be the same as the internal IP address of the upper level and must not conflict, and the internal IP address of the superior must be used as the gateway of the lower level.

If the DHCP service is enabled by the superior, the subordinate can set it to dynamically obtain IP or fix the IP, and when the fixed IP is set, the IP rule is the same as 2.

3. Other needs to be noted:

The private IP address of the modem and the private IP address of the router should not be on the same network segment.

The cat is in bridge mode and does not have DHCP service.

When implementing wireless functions in an existing wired network, you can use the wireless router as a wireless AP (wireless switch) by following the steps below

1. Connect and log in to the wireless router on a stand-alone machine, change the IP address of the LAN port of the wireless router to avoid conflicts with other devices on the intranet; Turn off the wireless router.

DHCP function and restart;

2. Connect the 1 2 3 4 ports of the wireless router with the router or switch in the wired network;

3. Connect the wireless network card in the operation network to the wireless router;

4. Configure the network parameters of the wireless network card (automatically obtained or manually configured, and the manual configuration parameters are consistent with the wired);

Wireless routing You don't need to set up a WAN port if you connect to it, it doesn't matter, don't worry about it.

Try using the wizard mode again!

This is simple, just do it a few more times! Don't care about the WAN address, the dialing address is different every time!

First of all, explain your company's network architecture clearly, which operator. Dynamic IP?? Optical fiber?? Or adsl. Or what!! How to network switches and routers. Layers of switches.

It may be that the DHCP address assignment was unsuccessful.

The address is not set, or the address cannot be obtained automatically.

The IP address of the local connection is the IP address that your computer network card gets from the uplink device (such as a broadband modem or router), including the gateway, but the IP address in the broadband connection is the public IP address randomly assigned to you by the operator's authentication server after your broadband account has passed the operator's authentication, and the two are completely different.

PPP is point-to-point, which means that logically two devices are directly connected, and there is no need to set up a gateway.

This is set up by yourself, and you generally use automatic IP addressing.

The default gateway refers to the default server address used by users to access the network. If the user is in a local area network, the default gateway may also point to the gateway server of the local area network. In general, if the user does not need to use a **server, or is not in a LAN with a gateway server, the default gateway may be blank.

However, if you set the ** server or the gateway server through the system function, but this column is still blank, it may be because the system settings have been tampered with, and it is recommended to fix it in time.
