What does network signal error 678 mean

1. Broadband Internet display "error 678", it is caused by modem damage, poor contact of network cable and network card, ** line obstruction, etc., 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.

2. If it cannot be solved, you can contact the local manual customer service for feedback.

Error 678 refers to the remote computer being unresponsive

The meaning 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, the port of the terminal board of the local office (the dry draft end of the telecommunications bureau computer room) to the process of returning data to the computer, and the data transmission problem will prompt 678 error. To put it simply, the network is not working.

<>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.

Error 678 is a common fault message encountered by PPPOE dial-up Internet users, which means that there is no network connection. The common cause of this problem is due to the obstruction of the communication between the user cat and the ISP service provider's equipment. The solution is as follows:

1. Check whether each interface is loose;

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

3. If the second step is invalid, then in the case of turning off ADSL modem, still disable the local connection, restart the computer, then enable the local connection, and then turn on the ADSL modem to solve the problem;

4. If the above steps cannot be solved, check whether the NIC light is on, if the NIC light is not on, check the NIC and network cable;

5. If the network card light is normal and cannot be solved, uninstall the network card driver and reinstall the network card driver;

6. If the above operation is invalid, contact the telecom department to confirm the port.

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.

Error 678: If the remote computer does not respond, it may be that there is a problem with the computer system, a problem with the broadband modem or line, or a problem with the operator's equipment room.

Error 691: Wrong username or password.

1.If the account is in arrears, 691 will appear if the account is stopped by the operator

2.The account number and password are entered incorrectly, for example, "0" and "o", "z" and "2" are not correctly distinguished.

3.If the binding is incorrect, the operator will generally bind the user's account with the corresponding equipment port in the data center, and if the place is changed and cannot be used, a 691 error will appear.

Error 676: ** busy, usually caused by a problem with the computer system or the last connection was not properly disconnected.

Error 769: The NIC is disabled, usually because the computer NIC is not successfully driven or the NIC is disabled.

You unplugged the route and plugged in the cat directly. Error**678... If you can't dial **, call the Netcom Service Department.

--Look at the cat's power

dslethement3 lights are fully on, try to turn off the power of the cat in the turn on to re-acquire the ip

Check whether the NIC is normal.

There is also a possibility of poisoning.

My suggestion is that if the cat is fine, it should be reinstalled.

This means that you can only dial from one device for this account, and if you are using this account for routing, then your computer is wrong to dial the number**. You'll need to disconnect the dial-up connection from the route and go back to the computer to dial again.

Error 678 The remote server does not respond, which is a common fault prompt 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.

Observe whether the Moden is synchronized, DSL (ADSL DC Link) (the signal light of the Moden is different for different manufacturers). If the sync light flashes, there is a problem with the ADSL line, or the moden is broken. If the above situation occurs, call the ISP maintenance personnel to repair.

678 means that the remote server is not responding, it means that the line is not available or the upend server is set up in a problem, if you confirm that there is no problem with the physical line connection and the router or computer is configured correctly and there is no fault, you need to contact the network provider to solve it. If the username or password of the account is incorrect, a 691 error message appears.

The 678 server did not answer.

The modem or other device is not off-hook. Check the number, then dial it. If it's a virtual private network (VPN).

connection, check the hostname or hostname of the target server.

IP address and try to connect again. Also make sure that the ** cable (network cable) is plugged into the correct slot of the modem (network card).

Hit your ISP**. It's all free. Ask them for sure yes. It may also be due to overdue payments or other reasons.

This is a problem with the device, I have encountered it many times, and you use the router belt to go directly to the router IP

Set your broadband number on it, don't understand to add me q448107854I can help you.

The remote computer is not responding.

Most of the lines are blocked, you can see for yourself whether the link light status on the modem is on.

Several aspects can lead to a 678 error.

The first broadband cat fault this needs to be consulted with the operator.

Second, if the system fails, you can find a notebook to try it, and you will know that the third is that the data port in the computer room is faulty, and you should also consult the operator if you want to find it, and fourth, if the broadband line is faulty, you need to find the operator to report the fault.
