I use Tietong to access the Internet, why can t I connect to the network, and the connection always

Did you use **? Remote control should not have, it should be that the remote computer (server) does not respond, and the iron pass ** asks.

Broadband can only be connected after a local connection, which is normal.

If you are using an electric modem, you must connect to the broadband after a local connection.

Analyzing your situation, it should be the reason for the slow network speed (Tietong has always been like this), it is recommended to check the line or ask Tietong directly.

The rail route is certainly not your local one.

As for the QQ display local problem, Tietong broadband problem.

Raillink Broadband can only be connected locally.

As for what Starlight Rapid is connected by telecom users.

I think there are four common reasons for disconnection.

1. Do you use Kaspersky Antivirus or Kaspersky Firewall, or is it similar to Kaspersky's incognito mode function? If yes,Then you just turn off this incognito mode,Don't be incognito on the network, this situation won't occur after stealth,Invisibility sometimes affects BT** speed,There is also P2P network TV。 A reboot of the machine or cat can sometimes do the trick, but it won't solve the problem at all.

The fundamental reason for this situation is that the broadband network you use (such as telecommunications, Netcom, Tietong, etc.) often has to detect your computer, and this situation will occur when the other party cannot detect your computer network card, and when this situation occurs, your network card does not get the IP address at that time, so this situation will occur.

It's not a big problem, though. Generally, this problem is not easy to occur, unless the broadband network you use needs to be adjusted to the network.

2. Check whether there is strong magnetic field interference in the place where the network cable passes.

Third, the cause of static electricity, friction has static electricity, let alone the computer. The computer's computer source conversion and display will produce static electricity, especially the computer's power conversion is in a high-frequency oscillation state of 500kHz is the most culprit of the chassis electrification, find a piece of wire, connect it to the ground wire on the power socket, and connect the other end to the iron post on the window sill. You can measure the voltage change of the front and rear chassis, which is not small.

The normal chassis voltage should be around 3 volts (I haven't measured it myself, my friend said, there should be no problem).

Fourth, use ADSL in addition

modem Internet access has certain requirements for the first line, one is that each joint of the line should be connected, and the other is in ADSL

The modem separator cannot be connected to any equipment before, such as: ** extension, anti-theft device, etc. When reconnecting the binding post of the junction box, it is best to wipe the ** wire and the binding post with fine sandpaper, and wrap the ** wire on the binding post a few more times when wiring, and then tighten the screws to ensure good contact.

Remove the first socket at home, use direct wiring, and it is best to use welding when connecting wires and wires, and then wrap them with insulating tape, anyway, you can't connect any equipment before the separator, so as to ensure that the junction box is connected to ADSL

The good line contact between the modem splitters ensures the quality of signal transmission.

There is also the problem of the operators themselves.

Unlikely, though.
