Anonymous users2024-02-11Dear users, hello:
**678 refers to the failure of the broadband**. To put it simply, the network is not working.
Solution: 1. Have you ever moved your computer recently? The operation method is: check whether your network cable with the adsl modem and the network cable connected to the computer is loose, and the ** cable with the cat is loose.
2. Confirm that the adsl modem dial-up is normal, because the IP automatically obtained by the NIC is not cleared, so when dialing again, the NIC cannot obtain a new IP address and will prompt 678. The operation method is to turn off ADSL modem, right-click the local connection to disable the network connection in the control panel, right-click the local connection to enable after 5 seconds, and then turn on the ADSL modem dial-up.
3. 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;
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 NIC light is normal, step 1 and 2 cannot be solved, uninstall the NIC driver and reinstall the NIC driver.
6. If the above operation is invalid, contact the telecommunications department to confirm whether the port network cable is loose.
7. There is another situation, if there are 2 or more computers, check the port of the router or switch connected to the computer, there will be a "678 error" if there is a fault here, then you can replace a good port.
8. Some of the network conditions are normal after telecom testing, and there is also a prompt of error "678", at this time, it is necessary to consider the conflict of various application software in the process of use, which will also cause the network to be unconnected. For example, "Yahoo Assistant", anti-virus software, or firewall have abnormal errors that cause the error "678". So, if you notice the error "678", you can try to temporarily uninstall Yahoo Assistant, quit the antivirus software, or temporarily turn off the firewall and reconnect to see if that solves the problem.
9. As a last resort, you can use the method of restarting the "cat" and the computer to see if it works.
China Telecom provides the best quality network communication services, old friends for new phones, Internet age cash, 100 Gigabit broadband free experience, ultra-clear TV ITV, telecom activities can be directly queried through the business hall.

2.Call ** to Telecom, they will test your modem data (you have to turn on the computer), if it can't be measured, it proves that there is a problem with the line or the modem is broken, you can call the telecom to repair the line or go to the telecom to replace the modem.
3.Create a network connection 2 in the online neighborhood, and network connection 3 to see if it can connect to 4If the network card is damaged, try it with a network card that is sure it is okay.
5.If the port is damaged, call Telecom to replace the port and try.
6.If none of the previous ones are true, then there should be a problem with the computer, and you can borrow a laptop to try. Personally, I think it is possible to reinstall the system or overhaul the motherboard.

Anonymous users2024-02-08It's a remote computer problem, not your problem, the account of Telecom dials 10,000 to report for repair, and other accounts are similar to the repair method. Don't be so nice to them!

Once you enter broadband in the router settings, the router will be automatically linked, so you don't need to manually link the broadband. First of all, you need to go to the router settings interface and set it up. Enter the IP address of the router in the address bar to enter the settings, and the operation will be very simple in the future, just set it up.
1. Has your computer been touched recently? In particular, have the ADSL modem wiring and lines been moved? Please check whether the signal light on the "cat" will flash (the cat is different, the indicator light is also different, mainly dsl, adsl, line, link, @等都是宽带信号指示灯), if you want to flash, check whether the line is connected to the pair (mainly on the separator, there are three ports, each port corresponds to a line, the connection method is the bus is the incoming line port, ** machine connected to the phone port, in addition to modem or adsl connected to the broadband cat, you can also directly connect the ** incoming line on the cat to try, This can rule out the bad separator), if the connection is still flashing, check whether the line has a joint, and the signal will not be stable if the line oxidation contact is not good (the crystal head or line of the line into the cat has a problem, which will also cause the line to be blocked. >>>More
Upstairs is equivalent to not saying,,, in fact, the local connection is the attribute of your computer's network card, that is to say, if your computer is connected to a network cable that can access the Internet, then the local connection in your computer will show "connected" or show "limited or no connection". I will tell you about a broadband connection. When your computer's local connection shows that it is connected, either your computer is connected to a fiber optic network cable, or your computer is connected to the cat (both modem), or your computer is connected to other network adapters (such as routers, switches, etc.), among them, if your computer is connected to the cat (the cat is dialed up to the Internet with ** line), then you need to use a broadband connection, you need to enter the network provider and password given to you in your broadband connection, and then connect, your computer can access the Internet. >>>More
