If the router is connected to the cat network, it can t go up, unplug it, and the network can go up.

Your cat may have a routing function, and the same network cannot use multiple routers, try setting your routing to dynamic IP mode.

1. Log in to the router (the IP address of the general router is, the user name and password are admin, you can refer to the back of the router or the router manual), select the WAN port setting in the network parameter option, and re-dial the network.

Specific steps: Step 1: Connect the ** cable. Insert the RJ11 plug of the ** cable into the LINE interface of the modem, and then use the ** cable to connect the phone interface of the ** cable with the ** machine.

Step 2: Turn off the power of the computer, connect one end of the cable with the modem (25-pin male end) to the modem, and the other end (9-pin or 25-pin plug) with the COM port on the main unit.

Step 3: Connect the power transformer with the Power or AC interface of the modem. When the power is turned on, the MR indicator of the modem should stay on.

If the MR light does not light up or keeps flashing, it means that it is not installed correctly or that the modem itself is faulty. For modem with voice function, you should also connect the SPK port of the modem to the line in port on the sound card, and of course, it can also be directly connected to output devices such as headphones.

2. Restart the cat, if there is a spare cat, replace the spare cat, and re-dial the network.

This is because the router is not installed and can be used, it needs to be set up, and the settings are as follows:

1. You need to connect the router to the computer with a network cable;

2. Enter the IP address of the router on the computer, generally 3. Log in to the router interface, and the login password is lowercase admin;

4. Find the WAN option, select PPPoE in it, and then enter the broadband account number and password to confirm;

5. It can be used in wireless network.

In the setting option, set the wireless network and enter the SSID is your wifi name, which is encrypted;

6. Click "Restart Router" in the system tools or other options, wait for a while to restart, and then you can surf the Internet.

When many users use a computer to connect to the network, they find that there will be a prompt of "the router cannot connect to the Internet", but many users do not know what this means, and they do not know how to solve it.

1. Extranet failure.

Take the home network as an example, the home network generally needs to dial up broadband, and then use the "modem" to dial up the Internet, which is commonly known as the "optical modem", if only connected to the optical modem (the kind without routing function), the user needs to manually dial in to access the Internet, but if the router is installed, the router will automatically dial up the Internet after setting. If you find that the router cannot connect to the Internet when you are connected to the Internet, the first thing to check is the indicator light of the optical modem. As shown below:

This means that there is no optical signal input, and the router cannot connect to the network through automatic dialing, which causes the optical modem to glow red for many reasons, such as external network failure, broadband arrears, fiber optic cable being cut off, etc., if you encounter this kind of problem, you can't solve it yourself, call customer service directly, and the other party will help solve it, and will inform the reason at the same time.

Second, the crash. Although the router is generally not damaged, but there is a crash, if the indicator light of the optical modem is normal, and does not emit red light, most of the router is caused by a crash, the router generally does not need to be turned on and off regularly, but long-term operation will cause the cache in the router to be full, sometimes power failure or program error, etc., will cause the router to lose its function. As shown below:

In this case, you only need to unplug the power supply behind the router, wait for about 10 30 seconds (you can also wait a little longer), and then plug in the power supply, and you can use it normally, but be sure to note that some routers have a small button behind them, don't press it at will, it is easy to empty the networking data in the router.

3. Line failure.

Although most users use the WiFi network to connect to the Internet, but the network cable between the modem and the router is realized, if the router has been moved or the modem has been touched before the failure, there may be a problem with the network cable between the two devices, even if it is not touched, with the increase of service life, the network cable in the middle will also age. As shown below:

In this case, you can unplug the network cable (both ends), carefully observe whether there is a problem, and then plug it back, or replace the socket to try, if it returns to normal, most of it is caused by more dust and poor contact, if it is still not good, you can try to use the optical modem dial-up to access the Internet, so that it can be determined that it is a problem with the network cable, and you can replace a network cable.

Digression: The reasons that cause the router to be unable to connect to the Internet are not limited to these, if the parameters in the router are set incorrectly, the hardware is damaged, the program is damaged, etc., such prompts will also appear, but this kind of problem is not something that the user can solve by himself, and can only find a contact with the merchant and ask him to help detect the router to determine the reason.

Note: Although the router is mentioned in the article, it does not involve the specific model, system version, and software version.

If you touch it, the network will be disconnected, indicating that there is a loose place between the network cable and the router.

Summary. Hello, 1. First of all, the cat connects to the WAN port of the router, and the LAN port of the router is connected to the computer.

2. Whether the route has been configured with Internet access parameters, if the router settings can't get in, you can try to restart the route and log in, and confirm the accuracy of the login IP when logging in (start--run--cmdEnter--- enter ipconfig all enter, you can check your IP and routing IP), pay attention to whether the computer automatically obtains the IP.

3. If you really can't log in, then after long press the REST key, the router restores the default settings of the factory, then you need to refer to the default routing IP, user name, and password on the label at the bottom of the router, enter the routing IP address in the browser address bar, log in to the settings page of the router, and set up the Internet (that is, after logging in, you need to configure the network information according to your network**, 4. If you are broadband dial-up Internet access, then you can press the wizard to set to PPPOE mode after entering the settings page, Fill in the correct Internet access and password, save and confirm. Restart your router.

Why can't the router get on the Internet when connected from the cat? There is a signal connection that is normal.

Hello! It's a pleasure to serve you, we have seen your questions and are trying to sort out the information for you, and we will reply to you within five minutes, thank you! ^

Hello,1、First of all, the cat connects the WAN port of the router,The LAN port of the route is connected to the computer2、Whether the route has been configured with Internet parameters,Router settings**If you can't get in,You can try to restart the route and log in,Confirm the accuracy of the login IP when logging in (start--run--cmdEnter--- Enter ipconfig all enter, you can check your own IP and routing IP), pay attention to whether the computer automatically obtains if you really can't log in, then after long pressing the REST key, The router has restored the default settings of the factory, then you need to refer to the default routing IP, user name, and password on the label at the bottom of the router, enter the routing IP address in the browser address bar, log in to the router's settings page, and set up the Internet (that is, after logging in, you need to configure the network information according to your network**, 4. If you are broadband dial-up Internet access, then you can press the wizard after entering the settings page, set to pppoe mode, fill in the correct Internet access and password, save and confirm.) Restart your router.

The solution to not being able to access the Internet is as follows:

1. Restart the cat, if there is a spare cat, replace the spare cat, and re-dial the network;

3. Reset the router (restore factory settings) and re-dial the network;

4. Replace a network cable and re-dial the network (mainly the network cable between the router and the cat);

5. Replace a router and re-dial the network;

6. Call the network operator service**, ask the other party to check whether the line is smooth, if the problem cannot be solved, you can ask the maintenance personnel to come to the service.

Press and hold the restart button for a few seconds, don't let go, and then turn off the power, and after a few seconds, press and hold the restart button again, turn on the power, and generally solve the problem.

Unplugging the cable between the cat and the router during operation can easily lose the network configuration.

Connect your cat, router and computer correctly, and try to see if you can enter the router settings interface, which is to enter the web address.

After entering, set the Internet information in the router interface, that is, your Internet username and password, and then click Save, the router will automatically restart after saving, and then see if you can access the Internet after restarting.

If 691 appears, it is usually because the account number and password are incorrect. Or you owe money. You can call the operator's computer to determine the account, password and fee. If it's okay, then it's probably the cat's problem.
