How Do I Adjust the Default Gateway and Subcode Cover of a Router?

Connect the cable that comes out of the ADSL cat to the WAN port of your router, and the remaining LAN port can be connected to your computer. Then set your IP address to, subnet mask and then open the IE browser, type in the address bar (there is a clear book) and press enter. The screen prompts you to enter the username and password, fill in the default username and password of the router (the username and password manual are generally admin) and then set the parameters according to the manual.

The network cable is directly connected to the WAN port of the wireless router on the cat, if you just bought it, then you directly lead two wires from the LAN port of the router to connect to the two computers, and the back of the router has an address and password, generally speaking, the account password is admin. You enter the web page of the router in the browser on any computer, enter the account password, and the setup wizard will pop up after logging in, if not, it doesn't matter, click on the parameter settings, select the WAN port settings, select PPPoE in the right WAN port connection type, enter the account password below, and click Save below to surf the Internet. This has nothing to do with two computers!

As long as you set up those two computers, you can directly access the Internet! Both the subnet mask and the default gateway you said can be obtained automatically! Even if you can't get it!

Then you can manually set your computer's IP address! The following DNS server is the provider of the Internet, and mine is the telecom one, so there is no difference between the first one and the second one! Just change the last digit of the first line of the IP address!

As long as the numbers are different from 2-254, you can even set the same settings for as many computers as you want! Generally speaking, you can connect to the computer network card and set it to get it automatically.

The main thing is to tune the router Not to tune the computer My method is to tune the router to always go online The computer is adjusted to automatic** Any computer will go online as soon as you check the network cable Mine is set up like this Open the IE browser, enter in the address bar", and then enter your username and password in the window that appears! Find it in your manual! Here I entered "admin" and "dare" as the factory default user and password!

Some passwords are: readsl or 12345 or admin If you can't enter, please poke the rear reset hole three times with a pin when powered on, and you can enter (the cat has been factory set)! Click on the WAN under the configuration on the left, this is the side page to enter the settings interface!

Here is the most important thing, I am a user of Inner Mongolia, and I have to ask your local telecom or Netcom department for specific settings! Select "0" for the bottom virtual circuit and click "Submit", select "PPPoe LLC" for the packaging protocol, select "disabled" for the bridge, and add the username and password to your Netcom application! (This username and password are the most important to fill in) don't say I don't know, I'm ......... dizzy

The factory setting of the router is the router address, generally plug the PC into the LAN port of the router, the router defaults to the DHCP function, as long as the PC and the router are connected, you can automatically get the address assigned by the router. You do not need to configure the IP address for the PC, and if you need to fix the IP address in special cases, you can set it on the PC.

Connect the 2 computers to the router, open IE input or route power-on status at any time) and fill in the account password for surfing the Internet, and the gateway can also be modified and saved. Just set the IP of the computer network card to be obtained automatically.

Default gateway: If a host cannot find an available gateway, it sends packets to the default gateway, which processes the packets. The gateway used by the host is generally the default gateway.

A computer's default gateway cannot be specified casually, it must be specified correctly, otherwise a computer will send packets to a computer that is not a gateway and will not be able to communicate with computers on other networks. There are two ways to set the default gateway: manual setting and automatic setting.

Subnet mask: Subnet mask, also known as network mask, address mask, and subnet mask, is a bit mask used to indicate which bits of an IP address are the subnet where the host is located, and which bits identify the host's bit mask.

The subnet mask cannot exist on its own, it must be used in conjunction with an IP address. The subnet mask has only one function, which is to divide an IP address into two parts: the network address and the host address.

Subnet maskIf the network number and host number are not specified, and the network number and host number cannot be distinguished, you need to use the subnet mask to achieve it. The netmask cannot exist on its own, it needs to be used in conjunction with an IP address. It has only one function, which is to divide a missing IP address into two parts: the network chain transportation address and the host address.

A gateway is essentially an IP address from a network to other networks. Router (called the default gateway under Windows.)

Default gatewayThis means that if a host cannot find an available gateway, it sends the packet to the default specified gateway, which processes the packet.

In summary, the subnet mask indicates which network segment the computer uses, and the two IP addresses belong to the same network segment.

It can communicate directly, and when it belongs to a different network segment, the default gateway is required to play a role; The default gateway is when computers in different network segments are connected together and allow them to communicate with each other. Studio shooting.

Preparation materials: computer, command prompt.

1. Press the win+r key on the keyboard to open and run.

2. After opening and running, enter "cmd" in the input box, click OK, <>3, click OK, and then enter the command prompt as an administrator, <>4, enter "ipconfig all" in the command prompt, press the enter key, <>5, press the enter key, you can see the IP address of the computer, the subnet mask and the default gateway are all displayed, <>

6. You can set a fixed address for network connection.

Automatically get with adsl all selection, with the default subnet mask set for the router and the default address set to.

IP and subnet masks.

As we all know, IP is composed of four segments of numbers, here, let's first understand the three commonly used types of IP

Class A IP range.

to the Class B IP range.

to the Class C IP range.

The subnet mask assigned to XP by default is only 255 or 0 per segment

The default subnet mask for Class A.

Default subnet mask for Class B.

Default subnet mask for Class C.

We don't use categories D and E. So I won't talk about it. You see that your IP is in the Class A address range, so the default mask is.

The mask you see when you enter the IP address directly and press the Tab key is the default mask, and you use the default mask.

The method and detailed operation steps are as follows:

1. First of all, open the start menu, then search for "Network and Sharing Center" in the search box, click the "Network and Sharing Center" option in the search results to open it as below screenshot shown, and then go to the next step.

2. Secondly, after completing the above steps, click on the "Change Adapter Settings" option in the new window as shown in the image below and proceed to the next step.

3. Then, after completing the above steps, find the NIC that needs to manually modify the IP, right-click and select the "Properties" option, as shown in the figure below, and then enter the next step.

4. Then, after completing the above steps, double-click the options marked with the red box in the image below, as shown in the figure below, and then enter the next step.

5. Finally, after completing the above steps, open the IP and DNS settings window, and you can fill in the IP address, subnet mask and gateway information, as shown in the following figure. In this way, the problem is solved.

Subnet mask

The network management fills in the router address, which is generally as follows:

DNS: Alternate DNS: This is the Sichuan Telecom provincial network port, if you know your local network port is better).

The subnet mask is based on the IP address, the subnet mask is different for different network segments, the gateway is the IP address of the outbound device, for example, your router is then your computer's IP configuration - the subnet mask is the gateway.
