What should I do if the computer broadband cannot be connected, and the broadband is disconnected, a

1) If it is a problem with the broadband itself, first directly connect the broadband network cable to test, if it is a broadband problem, contact the broadband customer service to solve it.

2) If it's a problem with the router, if it can be used originally, it can't be used for the time being, my own practice is to disconnect the power of the router and plug it in, and I'll take a look. In there is a factory reset.

You can use it in strict accordance with the instructions from the new settings, you don't understand, and it is not recommended to set it at will (this is under the premise that the physical connection is correct, sometimes the router is looking for the IP address.)

slow or failed, not that the router is broken).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

3) If you turn off the wireless switch, turn it on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, the network card driver is not or is not suitable, the network cable interface.

or whether there is a problem with the network cable, etc.

4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

Hello! Regardless of the ** setting, you can follow the wizard in the router to set it. Select Get Automatically. First of all, ask if you can use the same network as you can access the Internet. If you can access the Internet, first check whether the light of the network cable interface behind your host is on.

ADSL dial-up users should ensure that the IP address of the computer network card and the IP address of the ADSL cat are in the same network segment, for example, the IP of the cat is, then the computer IP can be selected in any one, the mask is, the IP address of the cat is different, then refer to the above analogy to set the IP address of the computer network card. In fact, ADSL dial-up can be obtained automatically after dial-up without setting up the DNS and gateway of the network card.

If you are connecting to a router, you must ensure that the PPPoE account and password of the router are set correctly and set to autodialing. You can try the network card to automatically get the IP address first, and you don't have to worry about connecting to the Internet. If you can't access the network, the DHCP service of the router may not be enabled, two ways, one is to enter the router to set up DHCP, and the other is to manually set the IP address mask, DNS and gateway of the network card.

Refer to the IP settings of the above computer directly connected to the ADSL cat dial-up (to ensure that the network card IP and the router IP are in the same network segment), in addition, you also need to manually set the DNS and gateway, DNS can directly ask the broadband provider, and the gateway can be set to the IP address of the router.

Computer broadband is connected + always shows that the network has been disconnected.

The local connection is connected and the broadband connection is disconnected. It's because the network can't be recognized, just restart the local connection. 2. The specific solution steps are as follows:

Left-click the Network Links button in the taskbar in the lower right corner of your desktop. Select Open Network and Sharing Center. Select Change adapter settings.

Select Local Connections, right-click, and select Enable. When the message "Enabled" is displayed, the network is successfully connected.

Citation: 1. Telecom detects that you share broadband with multiple people, and the telecom server disconnects your line from time to time. But if you ask Telecom, you will never find the answer, and Telecom will only push your own questions. The goal is to force everyone to install a separate broadband to generate revenue.

2. Your machine or your friend's machine is poisoned, and some viruses will affect everyone in the local area network.

3. Some people have opened some so-called software to speed up the Internet, but in fact, the effect is similar to the second point, which is to make others unable to access the Internet and be happy by themselves.

For points, install an ARP firewall, such as a 360 security guard, and enable the LAN ARP attack blocking function. Of course, it's best to unplug that person's network cable. The data in this LAN has special software that can be detected, and you can go online to find it, and you will know who is occupying the speed like crazy.

4. If the weather is too hot in summer, your ADSL or router may not have good heat dissipation, causing instability. Add heat sinks to these devices by yourself or blow them with fans, in short, it's OK to find a way to solve the heat dissipation problem yourself.

1.Virus, antivirus.

2.The network cable has been bitten by a mouse, check the network cable line.

3.The network card is broken, replace it.

4.System issues. Reinstall the system.

Kill the poison and reload the drive.
