What Do I Do If Error 678 Occurs When ASDL Cannot Be Connected?

The prompt of the error "678" for Internet users is generally that the network is not available, but some of the network conditions are normal after being detected by telecommunications, and the error "678" prompt also appears, which is annoying. In fact, the conflict of various application software in the process of use will also cause the network to be unconnected, and the error "678" prompt appears. During routine maintenance, telecom maintenance personnel have found that "3721", anti-virus software, or firewalls have abnormal errors that cause the error "678" prompt.

So, if you find the error "678", you can try to temporarily uninstall "3721", quit the antivirus software, or temporarily turn off the firewall and reconnect to see if that solves the problem.

Isn't it Netcom?

I feel the same way as you ... I was like that last night... It was just fixed today.

Method 1: Find your local Netcom office. Let them make the broadband port from scratch.。。

Method 2: Call 10060 to report... This trick is the most spiritual, no one dares not to come, if you don't come, you play 2 more times to ensure that he is fired by the boss. Ha ha...

See if your network card light is flashing, and see if the network card is loose.

Broadband Internet display "error 678", 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 after self-service troubleshooting, it is recommended to contact the local customer service to report the problem.

Symptom: Unable to connect to the Internet, webpage cannot be opened.

Meaning of Broadband Connection Error 678: When using ADSL dial-up, the local computer sends a request service to the terminal server through the network card, but due to problems with the network line or computer hardware, the terminal server cannot receive or return the request data, and when the local computer cannot receive the return information, the ** message of error 678 will be prompted.

Netizen summary: Broadband arrears, poor oxidation contact of the crystal head of the network cable, damage to the ADSL modem, and broken network cable are often the reasons for such problems!

Workaround for Broadband Connection Error 678:

Check if the adsl modem (commonly known as: cat) is working properly.

1.At present, most modems have panel indicators, according to the indicator light, you can judge the direction of the problem, first confirm whether the power power indicator on the panel is always on, otherwise check the power supply.

3.Check whether the LAN or Link indicator on the panel is always on, if the LAN indicator is always on, it means that the computer is directly connected to the modem normally, if the indicator is not on, you should check the network cable between the modem and the computer.

The flashing data indicator on the panel indicates that the computer is sending or receiving data from the terminal server, and usually when error 678 appears, the data indicator often does not light up, for the simple reason that there is no data exchange.

Check the local computer NIC settings.

After checking, if the adsl modem status is displayed normally, and error 678** still appears, you should focus on checking the local network card settings, first turn off the modem power, right-click the online neighbor, right-click the local link icon, select Disable, and then restart the computer, after the restart, right-click the local link icon according to the above steps, and then select Enable.

1.Damage to the computer hardware or poor contact of the network cable head will also lead to error 678 prompt, you can also try to replace a new network card, crystal header to solve the problem.

2.If you are using a router to surf the Internet, in principle, you should set up automatic dialing on your router (see: Router Settings), otherwise there may be an error 678 message.

I've encountered it, it's just to call 10,000**, ask for the password, and you can see if the plug of the network data is plugged in.

Broadband dial-up, error 678, which means that the remote computer is unresponsive, which is manifested as an inability to connect to the Internet and a web page that cannot be opened. Common causes and solutions are as follows:

1. If the broadband account or password is incorrect, check whether the account number and password of the broadband connection are correct. Some computers use routers to access the Internet without setting up automatic dialing, need to manually connect to the network, or accidentally enter the wrong account and password when connecting to broadband for the first time. Reconnecting after timely correction can generally resolve the issue of error 678.

2. If the broadband is in arrears, the terminal server will not be able to receive or return the requested data, and the local computer will not receive the return information, and error 678 will be displayed. At this time, it is necessary to pay the network fee in time, and the problem will be solved.

3. Poor contact or not plugged in of the network cable connector, check the network cable connector, sometimes the network cable connector will be in poor contact due to redox, resulting in good and bad network, very unstable. At this time, it is necessary to replace the new and *** network cable in time.

Fourth, having problems with the modem is the most common cause of error 678. First check whether the power power indicator on the cat panel is always on, otherwise check the power supply. Then check whether the ADSL broadband signal indicator (link) is always on, under normal circumstances, when the cat is connected to the power and network, the indicator will change from flashing to solid in 1 minute.

If it keeps flashing, there is a problem with the network connection.

Steps to solve the 678 error: first check whether the fixed ** line is open; From booting the computer and the cat; Remove the router; Restore the cat to its factory settings; Establish a dial-up connection from scratch; If you still can't use it, you need to contact your carrier to report the fault.

Broadband connection shows error 678, which means that when using ADSL dial-up, the local computer sends a request service to the terminal server through the network card, but due to problems with the network line or computer hardware, the terminal server cannot receive or return the request data, and when the local computer cannot receive the return information, it will prompt the ** message of error 678. The reason for this situation is generally that the broadband account is wrong or the login password is wrong. Broadband arrears; There is a problem with the modem ("cat") for short; The local connection is incorrect; Poor contact of network cable connectors due to oxidation, etc.

This is mostly the operator's problem, look at the hardware network in my computer where there is a yellow exclamation mark, if not, it proves that the network card is good, then call ** to your operator to let them solve.

Error 678 is The remote computer is not responding.

The process is as follows:

Step 1: Check whether the modem signal is normal, and restart the modem if it is not. If it is normal, see step 2.

Step 2: Ask the user if they have any software such as a firewall or 3721 Internet Assistant, and if so, suggest that the user log out.

1) Firewall and 3721 Internet assistant post-test: if the fault is solved, the cause of the fault is "user software problem";

2) If the fault still exists, enter the next step to continue processing;

Step 3: Instruct the user to check the NIC status and unplug the network cable

1) If the fault is solved, fill in: the cause of the fault is "PC hardware problem";

2) If the fault still exists, enter the next step to continue processing;

Step 4: In the case of conditions (the user has dial-up software, installation CD (win98 should have a network card drive disk), it is recommended that the user delete the dial-up software and network card driver, and then reinstall the network card driver and install the dial-up software

1) If the fault is solved, fill in: the fault symptom is "dial-up connection timeout", and the fault cause is "PC hardware problem";

2) If the fault persists, go to Step 7 to continue processing.

Step 5: Determine whether the ** line behind the modem is available and whether the splitter is connected correctly

1) If the modem can not be used, and the other ** of the billing number can be used, it is recommended to replace the ** line, and the cause of the failure is "the user's indoor line failure";

2) If all ** of the user's home billing number cannot be used, please call 10000 to report the disability. Step 6: If the above processing is invalid or the user cannot do simple cooperation, please call 10000 to report the obstacle.

The 678 error is generally a fault prompt that broadband ADSL dial-up Internet users often encounter, which simply means that the network is not available. Broadband ADSL dial-up Internet access uses PPPoE protocol connection, transmits data through ** line, uses ADSL special modem to realize data modulation and demodulation, the meaning of error prompt 678 is that the remote computer is not responding, which means that the instruction is sent from the computer to the network card to send data outward, including the transmission of ** line, and the port of the terminal board of the local office (telecommunications office computer room end) handles the data transmission problem in the process of returning data to the computer.

Hello, if it is on the network after a while, and then it will continue to be disconnected, and the next day it will be on again, this can first call the telecommunications company over there to help you test it, if you can't afford it, it should be the problem of the landline, I don't know if the landlord's landline is ** whether there is a noise or flash break, my home was the problem of the landline last time.

The dispenser is broken, you buy a replacement one, a few dollars, adsl that end to the cat, the other end to the **, this is definitely the problem, I am telecom broadband installation.

Is the login password right, when I appear 678, it's all a login password problem.

There is a problem with the service port of Telecom.,Generally, hit ** to let Telecom refresh the port (this can solve the problem immediately),Sometimes you can restart your computer (but sometimes it doesn't work)。。

If the above situation still occurs, it is recommended that you call 10000, which is definitely the service because they have to issue an order! That's why I just got to me!

The Internet company asked. If you have this situation again. You just call ** and ask the Internet company. They will do it for you for free or find someone to come to your door to help you deal with it. I've had this on my network.

It may be a network failure of the network dealer, or your wire is too old, you can check with your local broadband dealer.

No signal, 1You check if your local connection is disabled, and if so, click Enable.

2.Check that the cat is marked with ADSL or DSL, whether the indicator light is always on, if it is always on, it is basically that you have disabled the local connection, if the light keeps flashing, it is an external reason, you have to hit **, call the telecom master to repair.

Call Telecom to help you maintain the ,。。 The telecom server didn't help you connect well, so you didn't just install telecom broadband.

The remote computer is not responding, the computer room is the reason. Contact the provider.

The broadband light on the host does not mean that it can communicate normally.

Restart it first, if it doesn't work, it's the ISP service provider's problem. If you hit ** security, someone will go over to repair broadband.

You can call ** to Telecom, let them help you test your modem data (you have to turn on the computer), if you can't test, 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;

If it's not a cat problem, you create a network connection in "Online Neighbors" and see if you can connect;

The worst thing is that the network card is damaged, you can borrow someone else's computer to try it, or try it with a network card that is sure it is okay;

There is also a possibility that the port is damaged, so you can let Telecom try to replace the port;

If you eliminate the above faults, then it is simple, there is a problem with the computer system, you can borrow a laptop to use it for a few days, if the use is normal, you can reinstall the system or overhaul the motherboard (generally the current computer network card has been integrated on the motherboard).

It's your ** and the network's junction box that is broken, and it's good to have one more.

Come on, just go straight to the account and password and re-emerge it, I've encountered it countless times.

The troubles that used to happen to the landlord happened to the landlord, and I felt helpless!!

So give the recipe:

Fill up the DNS, like I did...

You can restart the router if necessary...

ok！Simple, clear and practical!!

There are many reasons for this, and sometimes you just need to reboot.

1. Telecommunications projects in the region are underway.

2. Call customer service.

3. Stop for one night.
