Computer Internet connection problems Sometimes the computer can connect to the Internet, sometimes

It's crowded! The transmission rate of your home Internet is too small, as long as you open some programs that occupy a lot of network resources, it will be busy, if you don't want to do this, don't open so many network threads at the same time, or buy a large traffic line like a service provider, preferably more than 1m.

Maybe you have too many programs running together on your computer, which will slow down the running of various parts, try to run fewer programs, it will be better, and my family used to do the same.

IP address setting problem Find my computer, properties, management, device manager, network adapter, and set up the router from scratch if you can't access the Internet The IP of each brand of router is different Swift like.

Change the router, see if it works, if it doesn't work, then you can re-pull the network cable to see it.

1. Whether the hardware such as network cable and network card is normal;

2. Whether the network is normal;

3. Whether the various settings are normal (such as whether the IP and other settings are correct) 4, the cause of the virus (check and kill the virus, some viruses will also cause the computer to not be able to access the Internet) 5, whether the network speed is selected correctly (whether the value of line speed is selected correctly is also related to whether the user can access the Internet, and the network card of the computer used by some users does not support too high network speed, and the network speed is set high, and the user cannot access the Internet).

6.If it is broadband, it needs a username and password, and if it is fiber, it needs an IP number 7Check to see if it's in arrears. Reasons such as the connection is not available.

There will be a red cross on the network connection, which is usually caused by these situations:

1: The network cable is broken or the crystal head is damaged, check whether the problem is solved, and replace the network cable to solve it.

2: The network card is not enabled or the network card is faulty, find my computer on the desktop of the computer, right-click management - device manager - network adapter - open to find your network card first try to right-click to enable, if it is enabled, right-click the properties, open the driver page to check whether the driver is working normally, if it is not normal, you can update or restore (after restarting).

3: Find the Network and Sharing Center in the taskbar in the lower right corner of the desktop, click on the local connection, and see if the network is enabled.

Because we know that if the network is limited or the operator is in trouble, the network icon will show an exclamation point instead of a red cross, which is usually due to hardware problems.

1. Maybe your network cable is loose and the crystal head is in poor contact, just plug and unplug the crystal head again. Second, maybe your network card is broken, just replace the network card. 3. There may be an error with your network driver, reinstall the network driver.
