Anonymous users2024-02-09In this case, if you exclude the cause of the network cable, it is generally a problem with the network card, try another piece!

Anonymous users2024-02-08Look at the network cable, whether there is a problem with the cat, and whether the external network is faulty! It feels like the network is not working!

Anonymous users2024-02-06I've also had this situation.,You can reconfigure the router.,And then try again.,If it doesn't work.,Just pull out the cat and the router all the wires and turn it on for a few minutes.,If it's not a problem with the router, it might be a problem on the DNS side.。
If you're using a wireless network, you'll also want to check the network card.

1.Poisoned by anti-virus or reinstalled systems.
Error checker network status pings your dns to see through.

Anonymous users2024-02-04It's from someone else.1, please check if the other computers connected to the router can access the Internet normally.
2. Check whether the IP address is correctly configured for the local connection.
3. If the IP is correct, please check if there is a problem with the network cable.

Anonymous users2024-02-03If the router is divided, the network connection must be smooth all the time. But there is no external network, that is, the second of the local connection network icon, the small computer diagram does not light up. See if other computers under the same router can access the Internet, if not, then set up a router, if you can change the socket of your own line in the router, redo the crystal head at both ends of the network cable, or the quality of the network cable, the network cable is a parallel line, then it is not according to the formal practice, because the eight cores only use four cores to work, and you can also move the computer to a place where you can access the Internet to try to see if it is a network card problem.
Substitution is the best way to go.

Anonymous users2024-01-30In this case, only the data is sent, not received, and most of the time is caused by a problem with the broadband connection. You can check whether the broadband connection is established and whether you can get an IP address.
Use the ping command to ping the gateway first, and see if the delay is big, if it is greater than 1, the quality of the network cable is problematic, and the signal attenuation is too large. If it is less than 1, then ping the address of the DNS server to see if the delay is large, if it is too large, it is a line quality problem with the telecom room, and you have to find a telecom operator to check the line for you.

Anonymous users2024-01-29Personally, I feel that it is a package, a package, and it will flash when receiving data, and I think there may be a package that does not receive a package, or does not send a package, and you can look at the data package to see what the number is, if there is one, but 5, then it will definitely not be able to access the Internet.
See if it's m routed and try to switch it on and off again If it's dialing, see if the name and password are right.
If it still doesn't work, you can try to reinstall the network card driver.

Anonymous users2024-01-28As long as you have access to the internet, that's normal.
Let me tell you, someone attacked your computer to send you spam packets, if you don't bother to redo the system, and then install 360 security guard first, the second step is to install Kingsoft net dart, adjust the mode to an untrustworthy state, and then the next better antivirus software! 360 doesn't work, (one of the best shackles on the market: it's better to buy a Kaspersky), and Norton does. >>>More
1. Has your computer been touched recently? In particular, have the ADSL modem wiring and lines been moved? Please check whether the signal light on the "cat" will flash (the cat is different, the indicator light is also different, mainly dsl, adsl, line, link, @等都是宽带信号指示灯), if you want to flash, check whether the line is connected to the pair (mainly on the separator, there are three ports, each port corresponds to a line, the connection method is the bus is the incoming line port, ** machine connected to the phone port, in addition to modem or adsl connected to the broadband cat, you can also directly connect the ** incoming line on the cat to try, This can rule out the bad separator), if the connection is still flashing, check whether the line has a joint, and the signal will not be stable if the line oxidation contact is not good (the crystal head or line of the line into the cat has a problem, which will also cause the line to be blocked. >>>More

The local connection can't be connected, is there a red cross on the computer icon in the taskbar? Generally, the network cable is not plugged in, and another reason is that your network card is not plugged in, or the "cat" is turned off, anyway, as long as the interface of the network cable is plugged in, the light is not on or flashing, and the local connection will not be connected.
