The broadband is just right and suddenly it can t be used, what s the matter with the broadband sudd

If a broadband fault occurs, you can use the following methods to troubleshoot the fault:

1 Use stand-alone dial-up, if you are using a router, please temporarily disconnect the router for testing;

2 Restart the modem and the computer;

3 Re-create the broadband dial-up connection and try to dial again. How to do it: Start the Program Attachment Communication New Connection Wizard.

If the self-troubleshooting still does not recover, you can log in to the mobile phone business hall Customer Service Broadband Fault Report for feedback, and we will get in touch with you as soon as possible.

Check the network card, driver, network cable, etc.

If the network signal and network equipment are normal, but the Internet is still not accessible.

It is likely that the IP address is set incorrectly or the auto-assigned address is not on the same network segment. The IP address needs to be configured correctly.

Click on "Online Neighbors" - "Local Connection" - "Properties"; Click on Internet Protocol in the Local Connection Properties window.

Do not rule out the router reason, turn off the router and wait for about 10 minutes before trying (or resetting).

We recommend that you troubleshoot in the following ways:

If you are using a router, disconnect the router for stand-alone dial-up test first;

If you have a modem device, you need to pay attention to whether the device is overheating, you can turn it off for a few minutes and then restart it.

If the connection drops when running the program alone (compared to if it drops while playing a game), it is recommended to restart the computer to try or reinstall the program;

If the entire network is disconnected, check whether the access cable and the network cable are loose or in poor contact, and try to reseat the line.

Check and filter out the disconnection caused by computer viruses and scan the whole disk.

2. If the problem cannot be solved after the above troubleshooting, you can contact the manual customer service of the home location to report the problem.

The mobile broadband suddenly can't connect to the Internet, it may be an optical modem.

Or there is a possibility that the cat may malfunction or have an incorrect password.

The first reason: it may be that the broadband account or password is wrong or forgotten: Now most families are using broadband as a way to connect to the Internet, and the use of broadband requires an account name and password, if the account number and password are wrong or forgotten, it will lead to broadband can not connect to the Internet.

The second reason is that the modem or modem may fail (such as damaged components, power cords falling off, etc.), or data blockage, resulting in broadband unable to connect to the Internet.

Extended Materials. The traditional ** wire system uses the low-frequency portion of the copper wire (below 4kHz). ADSL uses DMT (Discrete Multi-Audio) technology to divide the original ** line OKHZ to the frequency band into 256 bandwidths.

for the subband.

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 signal-to-noise ratio of a sub-channel.

The larger it is, the more bits are modulated on that channel, and if a sub-channel has a poor signal-to-noise ratio, it is discarded. ADSL can achieve a data transmission rate of 640Kbps uplink and 8Mbps downlink.

In general, it is a problem with the broadband itself, but it may also be a problem with the router, unplug the router and plug it back in. If the network problem is not solved, then you need to find an operator, because basically there is no broadband network.

It may be due to broadband arrears, and at this time, you only need to pay the bill again.

If the broadband fails, it is recommended that 2113 operate in the following mode as 5261: restart the optical modem, plug the optical fiber connector back into the 1653 and then surf the Internet for testing; Determine the status of the modem indicator to remove the router, create a broadband connection, and reconfigure the router.

First of all, you have to see what color the light on your light cat is now, if it is red, it is not a problem with your device, it is a problem with your network cable, if it is green, it is a problem with your device, you can choose to restart or set up the computer to use it again. Whatever the reason, as long as you can't connect to the broadband, you can call your service manager. There are professional personnel to solve it for you.

Failure to connect to the broadband caused by the network provider's own problems: This kind of failure can only wait for the network provider to ask you to solve it, but we have to judge for ourselves whether it is the network provider's fault. Here's how:

Just look at the DSL indicator to determine if it is a problem with the network provider).

It may be because of the arrears of broadband bills, as long as you re-pay the bill. It may be because the network cable is loose, just unplug the network cable and plug it back in. If there is a problem with the optical modem, you can contact the operator of the network cable and ask the staff to solve the problem of the broadband connection.

Then turn off all broadband power first, and then turn it back on again to see if you can connect, if not, call the broadband ** to consult, there will be a master to come to service.

If you suspect that there is a virus on the computer, you can use 360 antivirus to detect and kill.

If you are using China Unicom broadband, there may be one of the following reasons for not having an internet connection

1. If the broadband is in arrears or expires, you need to pay or renew it in time.

2. If the network cable is loose, both ends of the network cable need to be plugged in tightly.

3. If the device is used for a long time, the optical modem and computer can be powered off for 10-20 seconds, and then the power supply can be turned on and restarted.

The reasons why the home network is suddenly unusable are: broadband arrears, poor network signal around, faulty routers and other equipment, loose network cables, and replacement of equipment.

1. Broadband arrearsThe network operator forcibly shut down, and only needs to pay a certain fee to resume normal Internet access.

2. The surrounding network congratulatory signal is poorIf the signal is in a non-service state and there is no network, it can be fed back to the operator.

3. The router and other equipment are malfunctioningCheck the router and the modem. You can choose to have a network repairer come to your home to help you find out why you can't access the Internet.

4. The network cable is looseIf the contact is poor, you can choose to strengthen the network cable, and if necessary, you can unplug the network cable and plug it in again to solve the problem.

5. Replace the equipmentIt is possible that the transit facility of the network is faulty, and it is recommended to replace the device and try again.

If there is no problem, just call the 10000 fault repair directly.

Usually the device needs to be restarted, or the broadband server is down.

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. There are several reasons why the connection is not available:

The account number and password are incorrect, or your broadband has expired (if the bandwidth has not expired, please check that the account number and password are filled in correctly).

There is a problem with the created broadband connection (please delete the original broadband connection and create a new broadband connection) There is a problem with the network card driver (please update the driver or reinstall the driver).
