Dear users, hello.

Hopefully, the following will be helpful to you:

It is recommended that you restart the device, if not, remove the router and let the computer connect directly to the cat to see if you can dial up the Internet.

China Telecom provides the best quality network communication services, old friends for new phones, Internet age cash, 100 megabit broadband free experience, ultra-clear TV ITV to take home, 517 Telecom Day activities can be directly queried through the telecom online business hall or physical business hall.

Mobile phones usually have a black screen.

It can be divided into two types: one is a black screen in use, and the other is a black screen in standby.

Most of the black screens in use are caused by the third-party software of **, and this phenomenon is rarely caused by the software that comes with this machine. There may be two reasons: there may be a problem with the software itself, such as the software itself is unstable or does not match the mobile phone system, and uninstalling the software can solve this problem; If the software is not compatible with each other, it is necessary to install and uninstall the software one by one, and experiment to check which software is the problem.

If you find it, uninstall it, and the problem will basically be solved.

The black screen in standby is mainly due to the fact that the mobile phone will automatically turn off the screen if it does not detect the key trigger signal for a long time, that is, standby, when you need to use the mobile phone, the button will activate the circuit in the mobile phone, and then the screen will light up.

The reason for the black screen may be because the mobile phone system sends a command to light up the screen, but the screen cannot respond in time due to the delay in the transmission of the circuit, so the black screen is caused. In this case, there is no need to recover in a hurry, wait for a while or use the ** around you to dial the mobile phone with a black screen, if you can get through, this problem will be solved.

I hope that the call will be solved, and don't use any electrical appliances if there is no electricity, and the battery of the computer can't carry so much.

The wireless router has no power, and it's a fart.

1.Some landline phones themselves have the function of long-distance lock, see if it is locked2If not, then call 10,000 service ** for consultation.

See if it's closed for long-distance calls, or call 10,000 to ask.

Maybe the telecom locked the long-distance function, call 10000 to check the situation.

The broadband line and the ** line should be separated, and the two are not related.

You didn't have a junction box.

Your network cable is occupying your ** cable channel.

When you lose the internet, you can resume calling again.

You see if the interface is broken, the splitter.

Check the ADSL crossover, it is estimated that it is broken, either the crossover is plugged in the wrong port, or the telecom operator's computer room has jumped the wrong line, and the voice signal of your home has been cut off, but the ADSL is not broken.

Broadband Internet display "error 651" is caused by modem damage, network cable, network card contact is not good, ** line obstruction and other reasons, the treatment method is as follows:

1.If you have a router, power off and restart it first, if it still can't be used, please remove the router for the following operation detection;

2.Check if the modem signal light is OK:

1) If the hunger and dryness are normal, please try to deal with it as follows: restart the network card, unplug the network cable, and restart the modem;

2) If it is not normal, please try to deal with it as follows: unplug the ** cable, restart the modem, check whether the separator connection is correct and plug in the above cable.

If the problem cannot be solved after the above simple troubleshooting, you can contact human customer service for processing.

Call the network provider's customer service. Let them check it for you.

Broadband is down when it expires.
