What does it mean if the computer broadband connection shows error code 678? How to solve it? Conne

If your broadband Internet display "error 678", it is due to modem damage, network cable, network card poor contact, **line obstruction and other reasons, if there is a router, it is recommended that you can first power off and restart, if it is still not available, it is recommended that you remove the router and check whether the modem signal light is normal:

1. If it is normal, please try to restart the network card, unplug the network cable, and restart the modem;

2. If it is not normal, please try to unplug the ** cable, restart the modem, check whether the separator is connected correctly and unplug the above cable.

Error 678 refers to the remote computer being unresponsive

The implication is that the remote computer is not responding, which means that the data is sent out from the computer to the network card, including the transmission of the ** line, and the port of the terminal board of the local office (telecommunications office computer room end) processes the data transmission problems in the process of returning data to the computer, and the data transmission will prompt 678 errors. To put it simply, the network is not working.

There is an error in the broadband connection of the computer**678 is a fault prompt that is often encountered by PPPOE dial-up Internet users. To put it simply, the network is not working. The common cause of this problem is that the communication between the user modem and the ISP service provider is blocked.

Solution. 1. Turn off ADSL or MODEM, right-click the local connection to disable the network connection in the control panel, right-click the local connection to select enable after 5 seconds, and then turn on ADSL or MODEM dial-up; If it is a direct network cable to the home, the user can disable the local connection and then enable it;

2. Check whether the dialed username and password are correct, if so, delete the dialed connection, and create a new dialed connection to try.

3. Check whether the NIC light is on, whether the NIC cable is loose or intact, and check whether the NIC driver is correct. If the NIC light does not light up, replace the intact network cable, if it does not light up, it means that the NIC is broken or the driver is wrong, replace the NIC with a new one or reinstall the NIC driver.

4. Check whether the ADSL or modem power supply is passed, whether the line is connected normally, restart the ADSL or modem, and tighten the connecting wire.

5. If multiple computers use routers to access the Internet, you can try to remove the router and connect to InterNT. If you can access the Internet smoothly, it means that the router is faulty, and you should troubleshoot the router or replace it with a new one.

6. Check whether there is any arrears. If it is due to arrears, you can pay the broadband fee.

7. Call the operator to confirm whether it is the reason for the operator's line. If so, wait for the carrier to solve the problem and try again.

A few days ago, I also had such a problem on my computer, call ** to Netcom 10060 customer service, they sent someone to repair, it is a poor line contact, so you had better call**, report your account number, let them check it specifically, to see what the problem is.

678 Solution:

1. Check whether your network cable is plugged in properly and whether it has been accidentally moved. It includes the network cable interface on the computer side and the network cable interface on the cat or router side.

2. If there is no problem with the network cable plugged in, see if the cat's indicator light is flashing non-stop. That's the problem on the side of the broadband operators. It's not a computer room problem or a port problem under your community, etc., just call ** for repair.

The username and password entered are incorrect, and the connection cannot be establishedReason: The username and password are incorrect, call 10000 to ask.

There is also a situation that your broadband is in arrears, I encountered it once last time, and it is normal after the payment.

The process for error 678 (remote computer not responding) is as follows:

Step 1: Check whether the modem signal is normal, and restart the modem if it is not. If it is normal, see step 2.

Step 2: Ask the user if they have any software such as a firewall or 3721 Internet Assistant, and if so, suggest that the user log out.

1) Firewall and 3721 Internet assistant post-test: if the fault is solved, the cause of the fault is "user software problem";

2) If the fault still exists, enter the next step to continue processing;

Step 3: Instruct the user to check the NIC status and unplug the network cable

1) If the fault is solved, fill in: the cause of the fault is "PC hardware problem";

2) If the fault still exists, enter the next step to continue processing;

Step 4: In the case of conditions (the user has dial-up software, installation CD (win98 should have a network card drive disk), it is recommended that the user delete the dial-up software and network card driver, and then reinstall the network card driver and install the dial-up software

1) If the fault is solved, fill in: the fault symptom is "dial-up connection timeout", and the fault cause is "PC hardware problem";

2) If the fault persists, go to Step 7 to continue processing.

Step 5: Determine whether the ** line behind the modem is available and whether the splitter is connected correctly

1) If the modem can not be used, and the other ** of the billing number can be used, it is recommended to replace the **line, and the cause of the failure is "the user's indoor line failure".

2) If all ** of the user's home billing number cannot be used, please call 10000 to report the disability. Step 6: If the above processing is invalid or the user cannot do simple cooperation, please call 10000 to report the obstacle.

.How to solve various errors such as when dialing**?

There's a problem on the line! Call the complaint directly and ask someone to fix it for you.

The error **678 displayed when logging in to a mobile broadband user is usually caused by a line problem, and it is recommended that you troubleshoot the problem from the following aspects:

1. Restart the modem and plug in the optical fiber connector.

2. Judge whether the status of the modem indicator is normal, if it is abnormal (the modem lights up red, the PON light flashes, and the indicator light is abnormal), you can call 10086 to report the fault;

3. Remove the router and directly connect to the optical modem to dial-up to connect to the Internet, if the dial-up connection fails, you can further feedback and deal with it through the 10086 broadband fault reporting center;

4. Try to reconfigure the router.

Routing from the bandwidth band connection automatically performs the broadband connection, so you don't have to use the broadband connection to access the Internet, as for the appearance of 678 because your computer network cable is first connected to the route in the broadband cat, the computer can only drive the routing dial-up, can not drive the cat, and our cat is connected through the broadband connection after double-click dialing, your computer is not directly connected to the cat, of course, there is 678 pull (678: remote no response, that is, the network is not connected).

What is the broadband connection error 678.

The workaround for broadband connection error 678 is as follows:

Open [My Computer] - [Control Panel] - [Network Connection].

Check if the local connection is in the "Disabled" state, click Local Connection, if so, just double-click on the local connection and see the status change to "Enabled".

Error 769 error, most of them are disabled on the network card, just enable it! The causes are generally caused by the user's misoperation or some firewall software and computer viruses, which are very common.

If the local connection is not found, the driver of the network card is usually lost or the computer does not detect the network card, you can reinstall it.

If the computer is suddenly disconnected, it is recommended to use [360 Security Guard] - [Function Collection] - [Disconnected First Aid Kit] for diagnosis.

If you encounter problems such as not being able to open the web page or logging in to the chat software, it is recommended to diagnose the network comprehensively.

678 is a remote issue. It's good to call telecom to manual and call someone to get it down.

Error 678, the network is broken, if the local connection is not crossed, it is a problem with the network provider

Telecom, call the 10,000 artificial station.

The payment is in arrears or the network cable is broken.
