After using the router, the network is not normal

It may be that the routing is not good, look at it differently.

You see if the pinching of the network cable is correct.

Standard connection for twisted pairs.

Twisted pair cables are generally used for the cabling of star networks, and each twisted pair connects various network devices through RJ-45 connectors (commonly known as crystal heads) installed at both ends. The standard connection of twisted pair cables is not arbitrarily specified, and the purpose is to ensure the symmetry of the cable connector layout, so that the interference between the cables in the connector can cancel each other out.

Category 5e cable is the most commonly used network cable for network wiring, which is divided into two types: shielded and unshielded. If it is used outdoors, the shielded wire is better, and the unshielded Category 5 wire is generally used indoors, and because there is no shielding layer, the cable will be relatively softer, but the connection method is the same. In general, there are four pairs of thin wires twisted together and marked with different colors.

There are two types of connection for twisted pairs: EIA TIA 568B and EIA TIA 568A.

The tail of the crystal head is downward, from left to right, respectively set as 1 2 3 4 5 6 7 8, and the following is the distribution of each mouth line.

T568A line sequence.

Green-white, green, orange-white, blue-white, orange, brown-white, brown-white.

T568B line sequence.

Orange White Orange Green White Blue Blue Blue White Green Brown White Brown.

Generally straight-through line: both ends are connected according to the T568B line sequence standard.

Cross wire: one end is connected according to the T568A line sequence, and the other end is connected according to the T568B line sequence.

That is, there are several situations:

1) Peer-to-peer network (direct interconnection of the network cards of two computers): the cross-wire connection method is adopted, and the two termination methods of the network cable are different.

2) Network card and switch (or hub): use the straight-through line connection method, and the network cable is terminated in the same way.

3) Switch and switch (or hub) cascade: the cross-wire connection method is adopted, and the network cable is terminated differently.

Summary. Reasons and solutions for the router to connect to the Internet is not good: 1. Set up the dial-up connection according to the requirements of the operator, connect the stand-alone device such as the operator's optical modem, and ping the operator's gateway or DNS server address after dial-up the Internet;

2. If the ping is not working, it means that the operator's external network network is not working, just call ** to report to the operator for repair;

3. If the ping means that the external network network is normal, it has nothing to do with the operator's network, and the fault is on the router, restore the router to factory settings, and then reset it to eliminate the fault.

4. If the reset route is still faulty, the router may have a hardware failure and can only be replaced.

Can you tell us more about that?

Can you tell us more about that?

P.S. Obtain the DNS method, search the operator's DNS through a mobile phone and other devices that can access the Suncong network, as long as it is in the operator's network, it can be used as a ping test. Early search [].

4. If the reset route is still faulty, the router may have a hardware failure and can only be replaced.

3. If the ping means that the external network network is not changing, it has nothing to do with the operator's network, and the fault is on the router, restore the router to factory settings, and then reset the car to eliminate the fault.

2. If the ping is not working, it means that the operator's external network network is not working, just call ** to report to the operator for repair;

Pro: Reasons and solutions for the router to connect to the Internet and make Huai Ming dress up: 1. Set up a dial-up connection according to the requirements of the operator, connect the stand-alone device such as the operator's optical modem, and conduct a ping test to operate the gateway or DNS server address of Huaiqing Business after dial-up Internet access;

1. The bus of the broadband network is connected to the WAN port of the router, and the LAN port of the router is connected to the computer.

2. After starting the device, open the browser and enter it in the address bar to enter the wireless router settings interface. (If you can't get in, please look at the nameplate at the bottom of the router or the router instruction manual, the default settings of different models of routers are different.) ）

3. An account and password to log in to the router appear in the settings interface, enter the default account and password admin, or refer to the manual;

4. After successful login, select the interface of the setup wizard, which will automatically pop up by default;

5. After selecting the setup wizard, a window will pop up to explain that you can set the basic parameters of the router through the wizard, and click Next directly;

6. Set up step by step according to the setup wizard, select the Internet mode, usually ADSL users choose the first PPPoE, if you use other network service providers, select the following two according to the actual situation, if you don't know how to choose, directly select the first item to automatically select, convenient for novice operations, click next after selection;

7. Enter the account and password applied for from the network service provider, and go directly to the next step after the input is completed;

8. Set the wifi password, try to make the alphanumeric combination more complicated, and it is not easy to be rubbed off the network.

9. After entering correctly, it will prompt whether to restart the router, select Yes to confirm the restart of the router, and you can access the Internet normally after restarting the router.

Connected to wifi but no internet speed, the reasons for not being able to access the internet are:

1. The wifi itself is a problem, the wifi may not be connected normally, resulting in the inability to access the Internet;

2. Router problems, the router may be overheated or damaged;

3. There may be broadband arrears, resulting in inability to access the Internet;

4. The wifi name contains Chinese, resulting in some computers unable to connect to the Internet;

5. Computer system problems, there may be problems with the system, resulting in connecting to wifi but unable to access the Internet.

Suggested workaround:

1. Use other mobile phones or devices to connect to wifi to try whether you can access the Internet and rule out the problem of wifi itself;

2. Restart the router to try, or restore the router to factory settings, then dial up the Internet again, and reset the wifi according to the setup wizard, or change to a new router and dial up to connect to the Internet;

3. Contact the broadband customer service to confirm whether the broadband account is abnormal, such as arrears, recharge the broadband, and then dial up the connection;

4. If the wifi name contains Chinese, it is recommended to modify it to English or a combination of English and numbers before connecting;

5. If the above reasons are ruled out, it is likely to be a computer system problem for a long time, and it is recommended to restore the factory settings. See if that solves the problem.

The mobile phone is connected to wifi, but it still can't access the Internet, and the broadband master will tell you, **Something is wrong.

Use the router whether your network is good or bad your computer will show that the connection is normal, you better use the computer to connect directly to the cat, enter your fixed IP address to see if you can access the Internet, if you can't contact the operator directly, if you can, it means that there is a problem with your route.

1.Check that the router is configured correctly, especially if PPPoE is required, and whether it and the password are filled in correctly;

2.Check the physical wiring;

3.Log in to the router configuration page and check whether the WAN port has obtained the correct public IP address in the system status. If you can, check that the IP address and DNS of your local connection are correct, or if you're using a wireless connection, check that the IP address in the wireless connection properties is correct.

4.Confirm that your local carrier doesn't restrict the use of routers.
