Is it related to the disconnection of the local connection after booting up the ADSL modem?

Maybe it's a network problem

Sit down, drink a cup of tea, cheer up, and process your computer according to the following requirements, which will definitely help your computer to run.

It's a hot summer, the temperature is high, don't you feel hot? Devices (devices refer to: cats, routers, network switches, Hubble, computers, etc.) will not work if they feel hot; You may wish to refer to the following methods and adopt measures that you feel are acceptable to reduce the temperature of the working environment of the equipment.

A: Users who often surf the Internet for up to half a year should open the shell of the device after the power is off and clean up the dust in the device.

b: Place the equipment in a safe place for people, open the lid of the equipment, and use air convection to strengthen the contact surface with the air for natural heat dissipation;

c: Install a micro fan to the equipment to increase the convection of air and force heat dissipation;

D: If you are doing IT, I suggest you: after disconnecting the power supply, install a heat dissipation front plate on the heating parts of the equipment.

e: After the equipment is disconnected from the power supply, use a 3mm drill bit to drill many holes up and down the equipment to strengthen the air convection flow and improve the heat dissipation conditions;

f: To ventilate and dry the equipment, it is best to make an insulating bracket to support the equipment for natural heat dissipation;

H: Let the adsl cat sync first: restart the cat after powering it off.

As long as you do a good job in the above aspects, your failures will be eliminated;

Thank you for my answer!

Thank you: friend!

Dialing Error 678 Workaround:

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 go online smoothly,It means that the router is faulty,If the above problems are eliminated,It's the network card of the book itself that has a problem。 Consider exchanging machines with service providers.

If it doesn't go through the land by the device, it is a cat for a single computer, and from the above phenomenon, it should indeed be a cat problem. After changing to a new cat, it is still like this, and you should ask someone to check if there is any place where the ** line bound to ADSL is not connected. It's best to call ** to Telecom while asking them to monitor the records of you going online and offline on their computers for troubleshooting.

This kind of inspection is more powerful than a door-to-door inspection. Finally, if you find a problem, you will find someone to provide door-to-door service. I've encountered this kind of phenomenon, and it's fine after changing cats.

It was the telecommunications people who first found out on their website. In the end, they are willing to come to the door.

It is the problem of broadband lines, and the aging of the line is like this, and it is recommended to find a telecom to replace the problem of the first line.

Broadband error ** "678" indicates that the remote computer is not responding.

If the broadband error **678 is displayed, you can troubleshoot the fault in the following steps:

Step 1: Check whether the bound ** is normal and check whether the separator is installed incorrectly. If the line is abnormal, please dial 10000 directly, select the 4 button, and report the fault to the fault reporting system. If the landline is not bound or the fixed line is normal, go to the next step.

Step 2: If the binding fixture** is normal, check whether the adsl modem indicator is normal. If it is abnormal, power off the modem for 5 minutes and then restart it, and check whether the network cables between the modem to the NIC and the modem to the splitter are connected.

If possible, the modem can also be changed for testing. If the LAN is not lit, it means that the modem is not connected to the computer, or the network card is disabled, or the network card is bad, and if it is an integrated network card system, it may be relatively bad. If the modem indicator is normal, proceed to the next step.

Yours certainly isn't a problem with the system, there could be the following reasons:

1.It may be a voltage problem that causes the broadband cat to restart or the nanometer causes the connection to drop, find a shirt without a multimeter to test the voltage to see if it is normal;

2.Check whether the status of the broadband cat is normal when the connection is dropped, there is a DSL or whether the link light is always on, the DSL or Link light on the broadband cat indicates the communication status between your broadband cat and the operator's equipment room, it should be always on at normal times, if it is not bright or shiny, the biggest possibility is that there is a problem with your **line, directly call the customer service of the operator next to the ant to report the obstacle and let people check and repair: Telecom 10000
