Broadband device 100 Gigabit connection is normal to user CD light normal Error 678 ? What will be t

1. First confirm that the adsl modem dialing is normal, because the IP automatically obtained by the network card is not cleared, so when dialing again, the network card cannot obtain a new IP address and will prompt 678, the operation method is: turn off the adsl modem, enter the network connection of the control panel and right-click the local connection to select disable, after 5 seconds, right-click the local connection to select enable, and then turn on the adsl modem dial-up;

2. If the first step is invalid, then in the case of turning off ADSL MODEM, still disable the local connection (network card), restart the computer, then enable the local connection (NIC), and then turn on ADSL MODEM to solve the problem;

3. If the above steps cannot be solved, check whether the NIC light is on.

4. If the NIC light is normal, but steps 1 and 2 cannot solve the problem, try to uninstall the NIC driver and reinstall the NIC driver.

5. If the above operation is invalid, contact the telecommunications department to confirm the port.

The description of the problem is not very clear. Generally, there is a problem with your local computer room. Call 10000 and ask!

It's because there are so many people connected to the Internet, and you can connect to it after a while, and it's okay, it's the same in my house, sometimes it's connected all at once, and sometimes it takes a long time to connect

I've seen this phenomenon before! Error 678 means that the remote computer is unresponsive or unconnected! You can call 10000! They'll help you look it up!

<>1. Definition of Dialing Error:

Error 678 is one of the faults of broadband. The implication is that the remote computer is unresponsive. To put it simply, the network is not working.

Broadband dial-up Internet access uses PPPoe protocol connection, the meaning of error prompt 678 is, the remote computer does not respond, which means that the computer sends instructions to the network card to send data, the packet has not included the transmission of network cables, and the port of the terminal board of the central office (computer room end) processes the data transmission problems in the process of returning data to the computer.

2. Common reasons:

There are many reasons for error 678, such as: equipment problems in the computer room, backbone cable problems, wiring cable problems, user network cable problems, user computer network card problems, user computer system problems, etc., which may lead to error 678. Another reason is that if you use a router, you usually don't need to use a broadband connection anymore, and if you use it again, you will get a 678 error.

3. Solution:

1. Please confirm whether you are using a router, if you are using a router, the dialing operation is completed by the router, and there is no need to manually dial the number on the computer;

2. Please confirm whether there are any software restrictions such as firewalls or other Internet assistants, and if so, it is recommended that you log out and then try to dial up;

3. Please check whether the network card light is flashing, check whether the crystal head is plugged in, and push the network cable inward for testing;

4. Please deactivate the local connection after deactivation, and then re-connect the broadband connection, the specific method: right-click the desktop network neighbor, select Properties, right-click the local connection in the new pop-up window, select Deactivate, and then right-click the local connection later, select Enable, if the dial is still prompted 678, you can call the customer service to contact the engineer to check;

Note: Try not to re-insert the network cable multiple times, as re-inserting and changing the network cable multiple times may damage the water and land nano crystal head.

You click "Network Neighbors" on the desktop, and then click "View Network Connection" on the left. Then put the mouse on the right side of the broadband bar [Broadband Connection] click the right mouse button and click to disconnect, wait for 5 to 10 seconds and then click to connect, and that's it. If it's not good, just disconnect the [local connection] above according to this method, and wait 5 to 10 seconds to connect again.

Don't bother trying it over and over again, that's what I did. Hope it helps.

The old man is the host, in a word, I know that you use optical fiber, please plug the optical fiber directly into the computer and let me see, what computer interface is optical fiber port in your house? Enter ping t in the operation to see if the external network is connected, if it is connected, create a new connection, enter the account and password correctly, and it's OK, do you have a pen and a desk to buy a router for two dollars? Pull it around, should you steal vegetables from Happy Net?

What kind of computer do you have? Can be directly plugged into the fiber optic Internet access???

Optical fiber and ADSL are just carriers different, ADSL should use ADSL cat, and optical fiber should use optical modem (photoelectric converter).

Please, you first figure out what an optical cable is, and see**Your network card is just an ordinary Nvidia chip, and it is impossible to plug in the optical cable directly. Xiaobai.

You can change the parameters of your network card, 10 100m full-duplex mode to see if it is easy to use!

Find the operator, if the maintenance man says that you have a problem with the machine, let him find out the problem.

The network is not working, so start the computer again.

It should be the wrong account and password, if you use the router link, look at the router settings, or you are a telecom call 10000** to consult, I have also had such an error 678 before.
