The computer network at home is not connected, and an exclamation mark appears

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, from the new strict according to the manual settings can be used, I don't understand, it is not recommended to set it at will (this is under the premise of the correct physical connection, sometimes the router is slow or failed to find the IP address, 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, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

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

Summary. First of all, this means that your upper-layer network device is not connected to the Internet. That is, the computer has been connected to the internal network, but cannot access the external network.

Second, it is recommended to check the modem and router. 1.Look at whether the light signal light of the optical modem is always red, if it will, the external line is broken, it is recommended to find a broadband operator to report for repair.

2.Check whether the light of the router flashes red or yellow, if so, it means that the router cannot access the Internet, if the modem light is normal, then check whether the broadband is in arrears. 3.

Under the premise that the above is normal, the optical modem and router will be powered off for 20 minutes, and the voice separator will be plugged and unplugged and powered on again.

My computer is connected to the home network, and it says it's connected, but there is still an exclamation point.

Hello dear. As far as the description is concerned, the computer connection to the home network shows that it is connected, but there are still exclamation points for the following reasons, 1Your home network cannot be connected to the Internet normally, and you cannot access the external network.

2.The system can't connect to the Microsoft server, so it can't detect that it can surf the Internet normally. 3.

The network is complex, and the system detection is delayed.

4.As long as you can surf the Internet normally, the network shows that it is connected, and there are exclamation marks that can be ignored.

Above, can you understand? <>

You can't use the Internet normally.

Then at this time, your router modem cannot access the Internet normally. There is a problem.

First of all, this means that your upper-layer network device is not connected to the Internet. That is, the computer has been connected to the internal network, but cannot access the external network. Second, it is recommended to check the modem and router.

I believe that many people usually use the computer to surf the Internet, will encounter the situation that the computer suddenly cannot access the Internet, and an exclamation mark will appear on the network connection icon below the computer. Next, I will tell you about the rabbit.

Here are a few ways to solve it:

1. Regain IP.

Start, run, enter cmd, and enter :

ipconfig release simply releases the ip address ipconfig renew and gets a new one.

2. The IP address cannot be obtained due to network cable damage, and it can be solved by replacing it again.

3. Check for computer viruses, viruses or Trojan horses that will cause errors in network settings, so that the IP address cannot be obtained.

4. Delete the NIC driver, reinstall it, or update the NIC driver.

5. The problem of network equipment needs to be solved by restarting the network device.

If you are unable to access the Internet due to an exclamation mark on the broadband network connection icon of your computer, it is generally caused by IP address conflicts, it is recommended that you open the [Network Sharing Center], select [Change Adapter Settings], right-click the local connection properties, double-click IPv4, select Automatically obtain IP, then open [Run], enter cmd, and enter [ipconfig ew] in the command prompt to try to obtain the IP address again.

There is a problem with the NIC driver, or the IP address is wrong, or the firewall may be blocking the network.

In Device Manager, open the network adapter, right-click on the network card, uninstall or delete the driver, and reinstall the driver for the network card with Driver Life or Driver Wizard.

There is a problem with the connection or the network, you want to make sure that the broadband is normal first, and then check the connection line, and there is a possibility that there is a problem with the computer, in short, the problem is in these three,
