Routers, cats, etc. are all normal, the line is fine, and the IP address is also divided, why is it

The cat is broken. Alternatively, find a thin needle and gently insert it into the reset button on the back of the cat. to do a factory reset.

If you still can't, if you are in the warranty period, find a merchant or telecommunications department and ask for a free replacement. Or buy a new one yourself.

Picking up the cat can be on, which proves that the line and the cat are normal, and the problem should be on the router.

There are several types of routers, and different routers have different settings, in your description"When the cat is connected to the router, the WAN light does not light up, and the fourth light on the cat does not turn on", please confirm:

Is the router's upper WAN light, on or off, indicating a physical connection or a network connection status? If it is a physical connection state, the light does not light up, it is likely that there is a problem with the network cable, and the router WAN port may be closed or damaged. Replace a good network cable and try it to tell;

If the indication is the network connection status, that is, it will only light up after connecting to the Internet, it must be a problem with the router's WAN port setting. You can enter the router to check the WAN port, ADSL access generally sets the WAN port to PPPoe dialing mode, enter the broadband account number, password, set it up after saving, and then configure the LAN port, generally two ways: manually specify the IP and turn on the DHCP service, the specified IP needs to set the IP address of each computer to be in a network segment with the router IP, and the IP address on the computer does not need to specify the IP to open the DHCP service, as long as the IP address on the computer is set to automatically obtain.

If you are still unable to access the Internet after checking as follows, you need to change the router for testing. In addition, there is a possibility that some operators will limit the number of computers per ADSL broadband, please check whether your broadband is restricted, if it is restricted, you can only reduce the number of computers or change the tariff according to the operator's requirements.

Try to remove the router and connect to the network first, if it is connected, it means that there is no problem with the network. It should be noted that the local DNS is the IP address of the domain name resolution server in the settings of the network card, and you can consult the local network service provider.

Is the router online? If you don't need to manually assign an IP, you can do it all automatically.

Your default connection is not a local connection, choose a broadband connection.

Hehe! How do you know that your thread is good, once I also thought that everything was good, but the result was checked, and it was the thread problem

Hit ** and ask... Telecommunications companies. Is the line normal?

Have you filled in your account and password?

Summary. Hello,Your description is a little problematic.,It's the optical modem that has no network after connecting directly to the router, right?。

The cat at home is directly connected to the router and has a network connection, but there is no network?

Hello,Your description is a little problematic.,It's the optical modem that has no network after connecting directly to the router, right?。

My router is directly connected to the cat and has the Internet, but there is no network when plugged into the network cable at home.

Then you have to ask the installer if there is any wiring for the network cable socket in your room.

Because the network interface in the general room also needs to be connected to the optical modem before it is useful.

There is a network cable in every room, but there is no network in every room when the router is plugged in, and it can be connected but there is no network.

It's not like that, because the house generally has a pre-embedded network cable, and at this time, you need someone to help you install the light modem, and the network cable in your room can be used only when it is connected.

This router is plugged directly into the cat and there is a network.

I don't believe you took apart the network cable socket in your room, and there is no cable in the back.

Yes, you have to connect it through the interface in your room through the optical modem first, then it is useful for you to plug the router in the room.

Reason: The cat is a routing modem and needs to be connected using the following methods.

Steps. First, the connection method.

Routing modem --- router WAN port; The LAN port of the router --- a computer.

Steps. Second, the setting method.

Before setting, please disconnect the WAN port network cable of this router and plug it in after the setting is complete.

1. Set the IP range of the router.

In order to avoid conflicts, you can change the IP of the router to other IP segments in order to avoid conflicts (routing the LAN port of the cat). For example, it is modified to:

After restarting the router, the address to enter the router is.

2. Set up the router Internet access method.

View the IP details of the computers connected to the routing modem. (win+r--input, cmd--input:ipconfig all [remember: ip, mask, gateway, dns]).

Set it on the router, and select [Static IP] in the [Setup Wizard]. Enter the same as the IP address of the routing modem, the others: mask, gateway, and DNS settings.

Restart the router after the setup is complete.

The Mercury brand is relatively high-end, and there are more items to choose from. It's best to find the router's manual and follow the instructions, unless there is a screenshot. Generally speaking, enter the settings interface, find the dial-up Internet access form (PPPOE), enter the account password point, save it, and then restart the router.

In the WAN port settings, you can also clone your computer's Mac in the router.

No problem, just dial with the router.

1.Find a network cable to connect the LAN-1 port of the computer to the new router. (Please note that the WAN port of the router should not be connected to any network cables).

2.Set the IP address of the computer you are currently using to be automatically obtained;

3.Then type 192 168 1 1 in Internet Explorer (a little bit in between.) If the login interface appears, please enter: admin (the username and password are admin) to enter the routing setting interface;

4.Once you are in the router settings interface, click on the left side of the router settings interface"Setup Wizard", click Next;

5.In the "Internet Mode" dialog box, please select the "PPPoe" option, and then click "Next".

6.Then enter your broadband account and password for Internet access (the Internet access account and password given to you by China Telecom or Unicom must be correct).

7.Set the SSID (your wireless network name, do not change it to Chinese) in the "Wireless Settings" dialog box, and set your wireless network password (the password for you to access wireless in the future) in the PSK password

8.Save the settings, click Restart the router, and finally plug the network cable with the network into the WAN port of the router.

You need to set up the router dial-up before you can surf the Internet.

Router settings.

1.Enter in the address bar of the browser (browser, etc.) or, press enter to confirm, the account and password are admin (the login address and account password are written on the sticker on the back of your router).

2.Find the WAN port setting under Network Parameters (this is a TP-Link router as an example, other routers find similar settings).

3.On the page, select the PPPoE mode in the WAN port connection type, then enter the broadband account password, save it, and restart it.

These settings are correct, as long as the computer is connected to the router, you can access the Internet, no need to dial up.

The same as the gateway IP addresses of the router and modem, there is a conflict, which makes the router or modem's gateway unreachable.

Workaround:1Disconnect the router from the modem (modem, commonly known as the cat).

2.Look at the gateway IP address on the nameplate on the back of the router.

3.The system is connected to the router wifi.

4.Log in to the gateway IP address in the browser and open the gateway.

5.Go to the LAN port settings in Advanced settings.

Change the IP address of the gateway LAN port to avoid duplication with the modem. If set to.

First, remove the network cable between the cat and the router;

When the computer is connected to the router, enter the IP address of the router in the browser, and take it as an example.

You can change the LAN port to default to it.

Yes, you can modify the router, which has to reset the login IP address and password. Just set it up and restart the router.

Disconnect the wireless connection and connect the router with a network cable.

If the IP addresses are all the same, you can change the address of the router to the end.

Only connect the router, and then enter the router to change the address.
