Does Error 678 have anything to do with the NIC?

Error 678 means that the remote computer is not responding. It can be preliminarily determined that it is a network operator problem.

The taskbar does not show that the computer is connected, and the speed is 100Mbps. Indicates that the connection between the modem and the LAN is normal. Again, identify non-local issues.

The ipcongfig query returns a normal result, but the ping is not normal. It is more certain that it is a remote network operator problem.

It has nothing to do with your network card!

It's related, it's possible that the network card is broken! I am very experienced.

Never mind.. Error 678 is usually due to the wrong password or not being connected to the ** provider.

Contact a broadband company, it's a matter of the computer room, and let them transfer it for you for free.

Sometimes it's a bug, so it's recommended that you restart your computer. If not, it is not the wrong broadband domain name and password you entered. Re-enter the domain name and password when connecting to broadband.

678 No answer. If the ADSL device is fully on (except for data) and on, turn off the device for 5-10 minutes and then turn on the connection, if the link light is flashing, it is recommended to report to the telecom department for repair. Check that the network cable is plugged in.

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.

678 is that the remote server does not respond, it is none of your business, it may be that the broadband service provider is debugging the computer room, and it will be fine after a while.

The most common problem should be the wrong password, that is, the remote computer does not respond, and there may be a problem with the line, but this is rare.

It could be due to a problem with your ADSL machine, or it could be due to a problem with your cable.

Broadband Error 678 and ADSL Connection Error 678 are common broadband Internet connection failures, which are generally caused by network failures.

There is a problem with error 678: The remote computer is not responding, disconnected.

Error 678 Cause: The ADSL ISP server is faulty, the NIC is faulty, and the network protocol is faulty due to abnormal shutdown.

Error 678 Workaround:

Step 1: Check whether the modem signal light is normal, and restart the modem if it is not.

Step 2: Unplug the network cable: check whether the ADSL signal light can be synchronized, check whether the network cable is connected, whether the network card is working properly, if not, delete the network component and reinstall the network.

The meaning of error prompt 678 is: the remote computer is not responding, which means that the computer sends instructions to the network card to send data outward, including the transmission of ** line, and the port of the terminal board of the central office (telecommunications office computer room end) processes the data transmission problems in the process of returning data to the computer. To put it simply, the network is not working.

I used to be a computer novice.

The computer used is not good, and there are often problems.

I can't get on the Internet. Later, I experienced a long period of illness and became a limb Fengliang doctor, and the mistake of 678 is very easy to solve if you don't go to the Internet.

Determine if the cat is normal first.

The best way is to get a friend or neighbor to try the cat normally, and you can see from the cat's indicator light.

If the adsl doesn't light up, there is no network.

Call the telecom directly and ask them to fix it.

If the LAN does not light up.

It's just that the computer is not connected to the Internet.

Check the NIC of the lower NIC.

If the network card light is on.

The problem is basically in the connection line between the network card and the cat.

If the network card light does not light up, it is a problem with the network card (there are many computers with dual network cards.

You can try both) if the LAN light is normal.

ADSL lights are normal.

LAN lights are also normal.

But the internet light is not on.

That's the problem with the computer system.

You change the IP address to auto-generate in the network connection.

Because a fixed IP may not be connected to the Internet).

Or simply delete the broadband connection and re-establish one.

Then restart the computer, of course, provided that you must make sure that the cat is good.

If all of the above is checked.

The computer is still error 678

Then there is another possibility.

It is now the network ** business.

In addition to the telecom servers are relatively stable.

Other. Especially Tietong.

Server static is severe.

I'm going to use it.

Last time, I couldn't get on the net no matter how I got it.

As a result, the computer can be put on the ground.

Because the ground static electricity is discharged.

1. First confirm that the adsl modem dialing is normal, because the IP automatically obtained by the network card is not cleared, so the network card cannot get the new IP address when dialing again, 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, right-click the local connection to select enable after 5 seconds, 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, 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" solution.

4. If the NIC light is normal, step 1 and 2 cannot be solved, lead the user to uninstall the NIC driver, reinstall the NIC driver, and create a dial-up connection.

5. If the above operation is invalid, please contact telecom customer service.

1. Broadband Internet access shows "error 676" is generally caused by multiple incorrect dialing in a short period of time, it is recommended to check whether the Internet access and password are correct, and wait for 15 minutes before dialing attempt.

2. Broadband Internet display "error 678", it is caused by modem damage, poor contact of network cable and network card, ** line obstacle section inspection section, 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 cable on it.

If the problem cannot be solved, you can contact the local manual customer service to feedback the situation.

The PPPoE dial-up protocol that comes with the system is in use, you need to disconnect the PPPoE connection you are connecting to or restart the computer.

If the client goes offline abnormally, this prompt will appear when dialing again, it is recommended to turn off the modem for 5 minutes before turning it on, and then log in normally after the system automatically releases the user account.

Modify the physical address of the NIC.

If the fault is still not solved by the above methods, then it is necessary to consider the reason for the physical address of the network card, which is generally caused by the address pool is full or the physical address of your network card is stolen, and most of the users who have error 676 are caused by the physical address of the network card, so this method is the most effective solution for most error 676.

1) Right-click the "My Mingchen Computer" icon, select "Manage", select "Device Manager" in the left column of the pop-up window, and then double-click "Network Adapter" in the right sidebar, and select the network card currently in use.

2) Right-click to open the "Properties" of the NIC, select the "Advanced" tab, and select "Network Address".

3) Click "Value" on the right side and fill in the new physical address of the NIC (which is different from the original physical address) - a 12-bit hexadecimal number (as long as the new address you set does not happen to be the same as other people's laughter, there is no problem.) )

4) You can run the cmd command and run ipconfig all to view the physical address.

5) Restart the computer and the problem is solved.

It's because your username and password are wrong.
