What should I do if I have a broadband connection? Desperate for answers!

If you use a cat, first check whether the link light on your cat is normal (it should be solid under normal circumstances), and then check whether the network cable connection is normal. If the network cable and cat at home are normal, then you can only call the customer service of the operator.

You can ask operators such as China Telecom and China Unicom.

Mobile broadband users log in with an error**678 is usually caused by a line issue and can be recovered by following these steps:

Restart the modem and plug the fiber connector back in before surfing the Internet.

Determine the status of the modem indicator, for example, whether the WAN indicator is solid or flashing when the port is connected to the modem normally;

Remove the router, create a broadband connection, and reconfigure the router;

If the above methods still do not solve the problem, you can call the local 10086 to report the broadband fault.

691 Access denied because the username and/or password are invalid on this domain.

The user account was not registered with the domain listed, the password expired, or the information was entered incorrectly. If no domain is specified, the remote access server attempts to validate the username and password in the domain of which it is a member.

Retype your username, password, and domain carefully. If you are unsure of this information, contact your system administrator.

Broadband connection error 678

Broadband connection error 691

1. Broadband error ** "769".

The reason may be: it generally appears in the Win XP operating system, which is caused by the disabling or disabling of the local connection in the computer.

2. Broadband error ** "691 635".

There are several possible reasons for this:

1. There is an error on the domain name (wrong username or password).

2. The server does not respond (the user port in the computer room is wrong, or the account is not activated).

3. ** or overdue broadband payments.

3. Broadband error ** "678".

678 error** is usually caused by a large area, computer software, computer network card hardware, and some external factors.

Handling 5G is one step faster, the traffic is half cheaper than 4G, the broadband speed is 500M, and it is convenient and fast to log in to the online business hall of Guangxi Telecom to handle broadband, number card, traffic package, etc. with one click. Customer service No. 2 will answer for you.

It should be a variety of wrong numerical pronouns.

A set of ** represents a type of error.

When broadband Internet access, there is a dial-up can't be dialed, and the network can't be connected! The webpage can't be opened, so do you know the broadband error ** analysis and simple solutions? Here are some of the relevant information I have compiled about the analysis of broadband error** and how to deal with it easily for your reference.

Broadband Error ** Analysis and Simple Handling Methods:

1. Error**: 602-617 633

Cause: Dialer software installation error.

Workaround: It is recommended to reinstall after uninstalling.

2. Error**: 619

Cause: The server is too late to respond due to the last connection error and the interval is too short.

Solution: It is recommended to try again after 5 minutes.

3. Error**: 630 769

Cause: Hardware error, which may be caused by computer network card damage or network card driver failure.

Solution: Check whether the network card is working, open the computer network and sharing center - change the adapter settings - disable the local connection and then enable it; Or check whether the NIC driver is successfully installed.

4. Error**: 650 720 734

Causes: Network protocol errors caused by broadband access server failures, network card failures, and abnormal shutdowns.

Solution: Check whether the network card is working normally, open "Computer Network and Sharing Center - Change Adapter Settings - Connect Early" and then enable it; Or remove all network components and reinstall them.

5. Error**: 678 651

Causes: There are many reasons for this kind of error, such as poor contact with external wires or network cables, and network card damage due to the rental model.

Solution: Observe whether the optical modem indicator is normal, judge whether the external line is normal, and still can't solve the problem, contact the telecom operator to arrange the installation and maintenance master to deal with it.

6. Error**: 691

Cause: The username and password are incorrect, or the account is shut down due to overdue payments.

7. Error**: 692

Cause: Modem malfunction.

Solution: Check if the modem is turned on, or reinstall the modem's driver.

8. Error**: 718 738

Solution: Try again after half an hour or contact the telecom operator to inquire whether on-site maintenance is required.

If you are too lazy to deal with it, it is also a very wise choice to find a knowledgeable friend to provide door-to-door service, their response speed is definitely much faster than that of telecom operators, but the premise is that you have to take care of the food!

There is no strict definition of broadband. From a general point of view, it is the bandwidth that can meet the needs of various ** transmission on the network that people can feel, so it is also a dynamic and developing concept.

The traditional ** wire system uses the low-frequency part of the copper wire excitation and socks (below 4kHz frequency band). ADSL uses DMT (Discrete Multi-Audio) technology to divide the original ** line OKHZ to the frequency band into 256 sub-frequency bands with a frequency width. Among them, the frequency band below 4kHz is used for transmission of POTS (traditional ** service), the frequency band from 20kHz to 138kHz is used to transmit uplink signals, and the frequency band of 138kHz is used to transmit downlink signals.

DMT technology can adjust the number of bits modulated on each channel according to the situation of the line, so as to make full use of the line. In general, the greater the signal-to-noise ratio of a sub-channel, the greater the number of bits modulated on that channel, and if the signal-to-noise ratio of a sub-channel is poor, it is discarded. ADSL can achieve a data transmission rate of 640Kbps uplink and 8Mbps downlink.

When our computer is unable to connect to broadband, a window will pop up with an error connecting to a broadband connection and an error**. We can determine the cause of the fault based on the specific error** and solve it. The following is an introduction to several common broadband connection errors and solutions to Chunyuzao.

1. Broadband connection error 691: First, check whether the broadband user name and password are correct, rule out the possibility of wrong password, call the operator, and ask the operator to refresh the server (the operator picks up the computer room management server) port, if it is broadband arrears, the staff will remind you of the broadband arrears;

2. Broadband connection error 678: It may be that the operator's host server and the user's communication failure, then call the operator to refresh the main server port, if it is not a server communication fault, please check whether the ** line or optical fiber cable connected to the cat is damaged;

3. Broadband connection error 769: The error is due to the failure of the computer network card driver, check the network card driver under the network adapter in the device manager, and enable or install the network card driver;

4. Broadband connection error 651: Although the prompt is a modem error, the problem is that it is compatible with other brands of cats, at this time, you can unplug the modem power adapter and computer ** line splitter, turn off the computer and then turn it on for a few minutes.

The above are the common errors that occur when the computer is connected to a broadband connection** and the corresponding solutions, friends in need can refer to it.

First, error **678 or 769:
