Briefly describe the basic process of router settings, the most basic function of the router is .

1. Connect the WAN port of the router to the external line of the Internet.

2. Connect the computer with the link port of the router with a network cable.

3. According to the router manual, set the computer IP to the same paragraph. For example, the router manual says, your computer is set up, the subnet is used, and the gateway is used.

4. Open the browser on the computer and enter it to enter the settings screen.

5. Enter the user name and password, the general user name and password are the same: admin6, after entering, according to the Internet mode, dial into the PPPOE setting, IP with static IP settings.

7. If there are multiple Internet accessors, set DHCP

8. Enter the router system settings interface, select Save and restart the router to take effect the settings.

Disconnect the computer network cable and connect the network cable to any interface of the router [except for the blue one, which is used as a switch. 】

Open IE, type in the ** bar, and you can enter the router interface settings.

..What router?? If it is an SOHO-class router.

You can go to work in the settings.

If it is a router at the aggregation layer or core layer.

It depends on what protocol you have enabled for networking.

The most basic function of a router is that a single network cable allows multiple computers to access the Internet at the same time.

To explain the concept of routers in detail, you must first know what a router is. The so-called "routing" refers to the behavior and action of transmitting data from one place to another, and the router is the machine that performs this behavior and action, its English name is router, which is a network device that connects multiple networks or network segments, and it can "translate" the data information between different networks or network segments, so that they can "read" each other's data, thus forming a larger network.

To put it simply, routers have the following main functions:

First, network interconnection, routers support a variety of LAN and WAN interfaces, mainly used to interconnect LAN and WAN, to achieve different networks to communicate with each other;

second, data processing, which provides functions including packet filtering, packing**, priority, multiplexing, encryption, compression, and firewall;

Third, network management, routers provide functions including configuration management, performance management, fault tolerance management, and traffic control.

In order to complete the work of "routing", the relevant data of various transmission paths is saved in the router, and the routing table is used for route selection. The route table stores the flag information of the subnet, the number of routers on the network, and the name of the next router. The routing table can be fixed by the system administrator, dynamically modified by the system, automatically adjusted by the router, or controlled by the host.

There are two concepts involved in the name of an address in a router: a static routing table and a dynamic routing table. The fixed routing table set by the system administrator in advance is called static routing table, which is generally pre-set according to the configuration of the network when the system is installed, and it will not change with the change of the network structure in the future.

A dynamic routing table is a routing table that is automatically adjusted by the router according to the operation of the network system. Based on the functions provided by the routing protocol, the router automatically learns and memorizes network conditions, and automatically calculates the best path for data transmission when needed.

Optimal routing calculations and IP packets**.

Shunt! Divide a traffic into several!

The router works at the third layer of the OSI, and its main task is to receive packets from a network interface, and according to the destination address contained in it, decide which next destination address to go to (which may be the router or the destination host), and decide which network interface to go from.

The specific process of grouping the router is as follows:

1. The network interface receives packets.

2. According to the network physical interface, the router calls the corresponding link layer (layer 2 in the network layer 7 protocol) function module to interpret the link layer protocol header that handles this packet.

3. After verifying the integrity of the dataframe at the link layer, the router starts processing the IP layer of the dataframe.

First of all, in addition to a router, prepare at least 2 network cables with crystal heads to connect to the computer - router - external network. Plug the router into the power supply, connect the external network cable to the WAN port of the router, and use another network cable to connect the LAN port of the router (any one) to the computer.

Open the network icon in the lower right corner of the computer or right-click the "network" icon on the desktop, click "Change adapter settings" in the left options bar, and find "Local Connection".

Right-click Local Connection, click Properties to pop up the dialog box, select Protocol 4 in the dialog box, and click Properties to open it. Then the Get DNS server address and IP address automatically option will be turned on. Once set, type in your computer's browser:

Go to the server settings page. Enter the router password, which is usually admin.

After logging in, click Internet Settings on the left side, and select ADSL, dynamic password, and static password according to your broadband Internet access mode. ADSL needs to enter its own dial-up Internet account and password (basically eliminated); Automatic acquisition of one-time password is also the most common way to connect to the Internet. The static password needs to be filled in with some information provided by the operator.

...What router?? If it's a SOHO-level router, you can go to work in the settings.

If it is a router at the aggregation layer or core layer.

It depends on what protocol you have enabled for networking.

The choice of the router's Internet access method:

Broadband service requires dial-up, please select PPPoE dial-up. To dial up PPPoE, enter the broadband account password, and select Automatic connection as the connection mode.

2.If the higher-level device has DHCP, select DHCP Auto.

3.If the parent device has an IP address assigned, select Statically assign an IP address.

How to set up the WAN port of the wireless router:

1.The system is connected to the router wifi.

2.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. Check whether the dialing is successful.

3.Set up a way to access the Internet.

Go to the WAN port settings in Advanced settings.

1. Set the broadband account password dialing.

2. Dynamic and static IP mode, that is, set the IP information of the WAN port for connection.

3. The router is only used as a switch, and the LAN port is connected to another switch or router with broadband with a network cable.
