When the computer is connected to the broadband connection, there is an error through the WAN micro

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.

1. Check whether the network card and line are well connected.

2. Confirm that the broadband fee is not due.

3. Right-click on My Computer and click Properties.

Then click on Hardware and finally on Device Manager.

Take a look at the network adapter.

678 is a remote computer unresponsive.

To put it bluntly, the problem is on the server's side.

But only if the premise is: see if your cat is working properly.

Have you ever set up to turn off the network connection on some software?

This kind of situation is generally given to the operator customer, which can be solved.

The main thing is the problem of their computer room.

Sometimes you wait a while and then you get through, which means they took care of it.

This depends on your network environment, if you are a single computer dial-up Internet, then it is generally an external problem, you need to solve the problem of network operator staff, if you are connected to the router then do not dial again, in this case you are impossible to connect on!

1. First of all, confirm that the adsl modem dial-up is normal, because the IP automatically obtained by the network card is not cleared, so the network card cannot be obtained when dialing again.

After 5 seconds, right-click on the local connection to select Enable, and then turn on ADSL modem dial-up.

2. If the first step is invalid, then with ADSL modem turned off, still disable the local connection (network card), restart the computer, and then start.

Use a local connection (network card) 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, if the NIC light is not on, refer to the dispatch knowledge base: "The NIC light is not lit or.

often does not light up".

4. If the NIC light is normal 1 or 2 steps can not be solved, lead the user to uninstall the NIC driver and reinstall the NIC driver.

Identification number: 9973, how to set up ADSL dial-up connection under winxp method leads the user to create a dial-up connection, if 98 system recommends that the user be safe.

Install raspppoe software or ehernet300 software to connect.

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

Failure of the modem is the main cause.

7.If multiple computers are using routers to access the Internet, you can try removing the router and connecting 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.

8.If you are an ADSL annual subscriber, if this situation occurs during use, it may be in arrears, please consult the customer service center. In some areas, China Telecom or China Unicom users, in the case of arrears, can get through, but can not access the Internet, at this time it may also be in arrears, because now the telecommunications departments in some areas are not in arrears, but stop the use of the network.

9.Some brands of modem are also prone to error 678 due to insufficient power supply

1. Whether you use a router or not, there is a router, and there is no need for a broadband connection.

2. Your password or account has been entered incorrectly.

3. Is there a problem with your line connection?

Please check ** Lines . 678 is a line error. In addition, consult the telecom company to see if there is any arrears.

The local connection is disabled, or there is no NIC driver.

Yes, the remote computer is not responding.

It has nothing to do with your computer.

Just restart the next cat.

If you still can't log in.

Call your broadband operator's **.

Let them check if there's a problem with the signal.

Poor wiring link or signal problems with the carrier!! Nothing to do with the drive!!

Do you have a router here or a direct network cable? If it's a router, you shouldn't need to dial up! Dial 678 and you'll see it!

And if you are connected directly to the computer with a network cable, then the possibility of 678 is that the line is not good! Another thing that must be noted is to check the network card to see if there is a problem with the network card!

This is a personal opinion, I hope you can use it!

The route setting is incorrect, it is the ppop port that is not the port you said.

Check whether your network card is turned off, if you use a router, that is, the router is not set up, the easiest way is to call the broadband company**, report the wrong number on the line, they can detect where your machine problem is not?

A 769 error, in general, refers to:

1.The network cable has been disconnected.

2.The modem is disabled.

3.The modem driver is corrupted.

4.Spyware is running on the computer and it is getting in the way of connectivity. ,5.winsock needs to be fixed.

6.Third-party firewall software is blocking the connection.

7.It is also possible that the network card is loose, and it is okay to fork the network card again, my experience: most of the above 7, or the network card is disabled.

To see if your network card is disabled, right-click on my computer - Manage - Device Manager to see.

Go to the encyclopedia and take a look, the explanation is very clear.

If "Error 769" is displayed for broadband Internet access, it is usually caused by the network card being disabled or the network card driver is damaged

1. Disable and re-enable local connections

2. Reinstall the NIC driver

3. If the NIC is not integrated, clean up the NIC and replace a slot

Fourth, if it is 769 caused by the failure of the firewall program, it is generally solved by restarting the computer.

Generally, the password is wrong, WAN means WAN, and the WAN port is the interface to the external network.

The error **678 displayed when logging in is usually caused by a line problem, it is recommended that you troubleshoot 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 is abnormal), you can call 10086 to report the fault

3. Remove the router and directly connect to the optical modem dial-up connection 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.

Telecom 678 error** is due to: The remote computer is not responding.

The occurrence of 678 is not a problem with your computer, but a problem with the network.

You turn everything off and try it all on.

Error 678: Unable to connect to a remote computer;Try to connect to the server to solve the problem: Check whether the network connection in the room is normal and whether the NIC light is on. If there is no problem, it proves that there is a problem with the network, and you can dial 10,000 to request repair.
