How to set the parameters of the router s LAN port and WAN port?

First of all, you have to know that the network segment of the secondary router cannot be the same as the network segment of the higher-level router, for example, the network segment of your higher-level router is, then the network segment of the second-level router should be changed, that is to say, this x can be changed except for the number between 1 and 0-254, so that the network segment of the two routers is diverted, and the second point is that you need to know the setting information of the higher-level router, such as whether DHCP is turned on or others, such as the information of the higher-level router. DHCP is on, from, then we know, the IP address of the upper-level router can be obtained automatically from between 100-199, and the others can only be set manually, then we find the WAN settings in the second-level router settings page, which can be set in two ways:

A. One is dynamic acquisition, and the other is static acquisition, choosing to dynamically obtain this secondary router will automatically obtain an IP in the DHCP allocation interval of the upper level router, using static acquisition, we can manually set the IP

Subnet mask. Gateway, DNS, etc., for example, we can set the IP address to be an IP other than the DHCP automatic assignment of the higher-level router, but we can't set the gateway, for example, we can set it between 2-99 or 200-254, just find an IP, the subnet mask is C-type, the gateway is, DNS according to your local requirements to check it online or you can directly set it to become the gateway of the higher-level router. In this way, as long as the network segments between the higher-level router and the L2 router are different, and the acquisition method follows the information of the higher-level router, then there is no problem.

B: Another way is to use this secondary wireless router as an AP, that is, to turn this router into a wireless switch. As long as the network segment of the secondary router and the higher-level router are diverged, and then the DHCP service of the second-level router is turned off, the LAN port of the higher-level router is connected to the LAN port of the second-level router, and the WAN port of the second-level router is not connected to anything, so that the second-level router becomes an AP switch.

Wireless router WAN port parameter setting method:

1.Go to the gateway page.

Open a computer browser and enter the gateway IP address of the nameplate on the back of the router (generally, enter the gateway configuration interface.

2.Set up a way to access the Internet.

Go to the WAN port settings in Advanced settings. If the broadband service requires dial-up, select PPPoE dial-up, otherwise you can choose DHCP to get automatically. To dial up PPPoE, enter the broadband password, and select Automatic connection as the connection mode.

DHCP is automatically obtained, and no other settings need to be modified.

<>1. First log in to the management page through the management address of the router, (take TPLINK as an example), and then connect the computer network card with the LAN port of the router with a network cable, and turn on the power of the router;

3. Enter the previously set administrator username and password (if there is no setting, it is the default admin, admin) to enter the management page;

4. Enter the setting wizard or network parameters - WAN port setting to choose the Internet mode;

5. The vast majority of ordinary users use the PPPoE dial-up mode, so you can choose the PPPoE mode here. (A small number of self-applied fixed IP mode, these customers must know to choose the fixed IP mode).

For enterprise networks, with the increase in the number of users, its network applications are also more and more, when everyone uses a network cable, it is obvious that the network speed is getting slower and slower, if you can add one more line access, then you can greatly improve the speed of the Internet, due to the birth of multi-WAN port routers. Next, I will teach you how to set up the router WAN port, I hope it will help you.

1. The multi-WAN port router needs to process a large amount of data

Therefore, most of the processing chips with strong capabilities are used to prevent bandwidth abuse and malicious attacks, and can more comprehensively solve the needs of bandwidth upgrades, and the purpose of multi-WAN routers is basically the same as that of single-WAN routers, which is to connect the interface between the internal network and the public network and provide firewall function services, but there is an additional Ethernet address that can be used for a second Internet connection. It can control traffic load balancing with built-in intelligent management.

Second, multi-WAN port connection is generally used

The second connection mode is better different from the first connection mode, using different operators, so that different operators can backup each other, generally telecom and Netcom, which is caused by many insufficient bandwidth problems caused by insufficient bandwidth of cross-network operators.

3. When investing in the establishment of a new dual-WAN port router

The user must be very clear that they can actually have a second connection, because in some places there may not be a second line, or there is no network with another operator, and the user will not be able to provide the service even if he is willing to pay.

4. Cisco routers have built-in powerful and efficient network processors

Compared with the basic dual-WAN router, Cisco routers provide many additional features, such as bandwidth limiting function to solve the BT** problem, full Chinese configuration interface, load balancing of different WAN ports, etc., which is very suitable for small and medium-sized enterprises, offices, branch offices and organizations with broadband access needs.

5. Cisco routers also support bandwidth management functions

Multiple sets of access rules can be set to manage internal and external connections. Administrators can limit network usage by IP or service port to double the unblocking efficiency, and can arbitrarily set the settings to ensure bandwidth, maximum bandwidth and priority.

Sixth, for most users

The router can start working and balancing the load according to its basic settings, if necessary, you can adjust the load balancing, backup function attributes, bandwidth management and firewall functions by setting the interface, which can make the use of bandwidth more efficient, users can select relevant attributes on the status page of the router to detect their status from time to time, and can also see the status of its WAN connection and the distribution of traffic.

1. WAN is the gate;

2. The LAN port is the room door in the unit;

3. WAN together with the equivalent gate is open, you can go out to play, go to the street, go to the park, anyway, go anywhere you want;

4. LAN and the door of the room equivalent to the unit are open, and you can walk around in several rooms;

5. If the WAN is not connected (the door is closed), you can't go;

6. LAN is not connected (the room door is closed), so you can only stay in your room. LAN is connected, and with the key (LAN does the relevant access rights settings), you can walk around several rooms!
