676 error. It also didn t work to reinstall the system

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.

Second, the 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, 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.

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

Let the operator check whether the MAC address of your network card has been blocked.

Or change the MAC address yourself and try again.

Your network card driver is wrong.

Don't use your own drive every time you install the system.

You can use the driver wizard to drive it.

If it weren't for the drive.

Then you just like the brother just said to change it directly.

Whether there is a problem with the network card, try it again; If you buy a new one, you should have a warranty, so look for a dealer.

You change the MAC address of the network card, try it, it should be no problem, if it doesn't work, you can change the card network card.

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

-- Kellybye of Experience

If none of the above methods can solve your problem, you can try the reset of the adsl modem two or three times and try again.

Another: ADSL modem device damage can also cause error 678, although on the surface it seems that ADSL modem is working normally, but it is a connection failure, the author has encountered such a problem, and finally replaced one.

678 is Netcom's error** You call Netcom customers** Netcom does not charge for door-to-door visits.

PE Down:

Delete the hard drive and repartition it.

Load the ISO file into the virtual drive, and open and install it in the drive.

The first thing you need to do is make sure that your ISO image file is copied without errors, ......

I strongly suspect that the software installed in the system is not good, so you can try another one.

There is a problem with your image. You can find a new system image.

Try it with Chinese cabbage U disk start.,That's what I use.,I just reinstalled the notebook yesterday.。

You take a look at the installation package of the USB flash drive.

If the U disk installation system will not, you can directly burn the U disk and install it.

678 is a connection error.

Broadband connection can not be, there is a "678" error2007-08-22 Wednesday 14:26 My computer is my friend with a car to help me bring over, I don't know what's going on after taking the Internet connection can't be connected, there is a "678" error, the system is reinstalled, the network cable is no problem, the network card is also checked no problem, the new dial-up, the user's computer can be on, their own is not good, I don't know the reason for **, please point to the high finger, thank you!

Suggestion or Solution:

First of all, check whether the contact between the network card and the network cable is normal, if it is the network card light (just behind the chassis where the network cable is connected) should be on, the local connection should be enabled, this can be seen in the network connection window in XP, 2000. If it is ADSL, check if the signal light is solid, if not, call 10000. If yes, please try to restart the adsl cat first, and pay attention to the network firewall you installed, such as Rising and the like, whether it is set to allow connection to the network, if the firewall is set to not allow, usually Rising in the taskbar small icon, that is, the place that looks like a small shield will be marked with a red cross, when you allow the small fork will not appear generation.

If it still doesn't work, notify the ISP.

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

You turn everything off and turn it on.

Error 678: Unable to connect to a remote computer.

Issue; Attempts to connect to the server failed.

Solution: Check whether the network connection in the room is normal and whether the network card light is on. If there is no problem, it proves that there is a problem with the network, and you can dial the 112 fault station to request repair.

Is it necessary to install the server software to access the Internet with the server?

Suggestion or Solution:

It's easy to find.

Generally, there are two possibilities, one is the telecommunications problem, the other is the system problem, if the installation system is still 678, then you can find the telecommunications.

The "Error 769" message is displayed for broadband Internet access, and it cannot be connected to the specified target, which is caused by the following conditions, and you can troubleshoot according to the corresponding situation:

1. The NIC is disabled. You can right-click on the neighbor, left-click on the properties to open a new window, double-click on the disabled neighbor or right-click on the local connection, left-click to enable, enable the network card, and troubleshoot.

2. The NIC driver is not installed. You can enter the device manager (right-click on my computer, left-click on properties, click hardware, click device manager), see if there is a yellow question mark in the screen, there are other devices written behind, there is a yellow question mark written behind the Ethernet controller under other devices, right-click to update the driver software, and follow the prompts to install the network card driver.

3. The computer does not detect the network card. In Device Manager, if there is no corresponding network card device information under the network adapter, and there is no Ethernet controller under other devices, you need to open the chassis, clean up the network card, replace a slot, and then restart the computer to see if the network card can be detected, if so, install the driver. If it still doesn't work, ask a computer company to check the network card and motherboard.

If the NIC is integrated, you need to go to the BIOS to check whether the device is disabled, and if so, enable it. If not, deactivate and purchase a new NIC if not.

4. The NIC driver is installed incorrectly or conflictingly. In Device Manager, if there is a yellow exclamation mark in front of the network card under the network adapter, uninstall the program and check if there are other redundant network card drivers. Then reinstall the driver correctly.

5. 769 caused by firewall program failure. Rising Firewall 2009 virtualizes a network device, and after the first installation, it will conflict with the network card, causing a 769 error. This situation can usually be solved by restarting the computer.

If error **769 occurs, usually the NIC driver is disabled, it is recommended that you troubleshoot from the following aspects:

1. Check whether there is a "local connection" computer symbol in the lower right corner of the computer monitor, and whether the local connection is disabled.

2. Check whether the computer network card is disabled;

3. Check whether the NIC or NIC driver is normal.

Error 769: Unable to connect to the specified target.

Information characteristics: There is no local connection in the online neighborhood, and there is no adapter in the computer hardware device.

Problem: This is when there is a problem with your computer's network equipment.

That is, a problem with the network card. There are three scenarios:

1: The network card is loose or not tightly plugged in (this is mostly the case).

2: Integrated network card, motherboard burned!

3: Independent network card, network card burned!

Here are all the most likely causes and how to fix them:

1. There is a buffer period for the system delay caused by the temporary busyness of the broadband system, just like we can't post normally all the time.

2. Check whether your computer has a network cable and broadband connection, and check whether there is a fault.

3. There are too many junk files on the computer hard disk, which directly occupies the memory, resulting in the slow speed of opening other web pages4. The computer system vulnerability is forgotten to be repaired in time, resulting in the spread of viruses and directly affecting the network speed.

5. It may be a problem with your computer operating system, it is recommended to install the system from the new installation 6, broadband system maintenance, it takes a period of time to see the above is the most complete cause and solution.

Good luck to the watchtower lord reference, o( o thank you.

Usually, the error at the beginning of 6 is generally a communication problem with the server, this is very troublesome and difficult to solve, you can call us except for this account problem, the error at the beginning of 7 is generally a network card problem, this is easy to solve, especially the 769 error, is the network card disabled. If you get other errors starting with 7. You can check the working status of the NIC and whether the protocol is complete.

How to solve the ADSL broadband Internet access prompt "676: ** busy"?

Solution. It can be tested by the following scenarios.

1. (1) Restart the modem first, it will generally return to normal, if it still doesn't work, it is recommended to restart the computer;

2) The test can be carried out by redidial ADSL multiple times;

Note: Auto-redial can be implemented in the "Options" section of the connection properties.

2. You can reset the modem (generally there is a reset button on the modem), and it is recommended that the user check the connection and restart the computer;

3. Run the following two commands on the command line: ipconfig renew and ipconfig release, to release the IP address in this way;

4. If the problem cannot be solved through the above methods, there may be problems with the telecom operator's server or network line, and it is recommended that the user change the time period for testing, and contact the telecom operator invalidly.

Cause analysis. It can be caused by faulty user modems, faulty network cables, faulty user systems (mainly network cards), and telecom carrier line or server issues.

You take a look at it, reinstall the network card driver, and take a look
