What should I do if the wireless network card cannot be connected to the Internet?

1. If you are using a wireless network card that cannot access the Internet, the handling method is as follows:

Check whether there is China Unicom 3G or 4G network coverage in your area;

Check that the Wi-Fi card is plugged in. If not, plug it back in;

Check if there is a problem with the driver. You can remove the wireless card driver and reinstall the driver;

Prepaid users can check if there is an account balance. If it is not enough to pay for timely recharge;

Check whether the traffic usage in the current month exceeds the maximum traffic limit. If it is unavailable this month, the Internet access function will be automatically restored in the next month.

2. If this is not the case, it is recommended that you contact the local Unicom customer service for verification, and the actual situation is subject to the local policy.

1. Open the "Service" management interface first, find "DHCP Client", "Network Location Awareness", "IP Helper", "WinHTTP Web Proxy Auto-DiscoveryService", and "Network List Service" to see if the current status is "Running".

If the "Startup Type" is "Manual", right-click and click "Start" in this service;

If the "Startup Type" is "Disabled", right-click on the service and select "Properties", set the "Startup Type" to "Startup" on the interface that appears, click "Application", then click "Start", and then click OK.

Once all the services involved have been completed, try to reconnect to the wireless network.

2. Use the command to try to re-obtain the IP address.

Press the windows key and the R key at the same time, enter cmd and click OK, then enter "ipconfig release" and press the enter key, and then enter "ipconfig new" and press the enter key, it will try to obtain the IP address again, and you can test whether it can be successful.

3. If the above operation is invalid, you can try to reset the network configuration and then restart the computer for testing.

Press the Windows key and the R key at the same time, type cmd, click OK, then type "netsh winsock reset" and press the enter key, wait for the display operation to be successful, and then restart the computer for testing.

4. The above operation is invalid, you can try to reinstall the driver of the wireless network card and then test.

The possible reasons why the wireless network card cannot reach the network are as follows:

1. No 3G or 4G network;

2. The wireless network card is not plugged in;

3. There is a problem with the driver of the wireless network card;

4. The balance of the prepaid user's account is insufficient;

5. The traffic used in the current month exceeds the traffic cap value;

6. The wireless network card body or USIM card is faulty.

The workaround is:

1. Use it in places with 3G or 4G networks;

2. Reinsert the wireless network card into your laptop;

3. Delete the wireless network card driver and reinstall the driver;

4. Recharge; 5. It will not be available this month, and the Internet function will be automatically restored in the next month;

6. If the above possible fault causes have been ruled out, please go to the business hall to check the wireless network card body or USIM card.

Hello dear! 1. "Start" - > Control Panel "->Network Connections", right-click "Wireless Network Connections", and select "View Available Wireless Connections". Note:

If you do not have a "Wi-Fi connection" in your "Internet connection", please contact the after-sales department of the computer manufacturer. 2. If the computer is currently using the Windows wireless management tool by default, then the list of results for searching for wireless networks should appear. Tips:

If the list is empty, it means that the laptop has not found any wireless networks, please click "Refresh Network List" in the upper right corner. 3. It is recommended to set the computer to an adaptive state that can connect to any available network, which is already such a setting by default, you can right-click on "Wireless Network Connection" and select "Properties", enter "Wireless Network Configuration" and click "Advanced", and confirm that the selected wireless working mode is "Any available network". 4. If you click "View Available Wireless Connections", the result will be a prompt for Windows: "Windows cannot configure this wireless connection......This means that another program (a tool provided by the notebook manufacturer) is managing the wireless connection.

Summary. The reasons and solutions for the wireless network card to be connected but unable to access the Internet are as follows:1

The first reason is that there is a problem with the wiring or a problem with the optical modem, you can check them one by one. If the LOS indicator turns red or flashes continuously, then it may be that there is a problem with the modem or the line signal is not good, and packets are lost when transmitting data. In this case, you can call the broadband operator and arrange maintenance personnel to deal with it.

2.If there is no problem with the optical modem, you can check the router to see if the WAN has obtained the IP address, whether it shows that it is connected, and if it is not connected, you can restart the router or restore the factory settings. In addition, you can also connect the modem to the computer to test it and find possible problems.

Take down the router first, then connect the optical modem to the computer, use broadband dial-up to access the Internet, and then check whether the network is normal, if it is normal, there is a problem with the router.

If there is no problem with the optical modem, you can check the router to see if the WAN has obtained the IP address, whether it is displayed and closed, and if it is not connected, you can restart the router or restore the factory settings. In addition, you can also connect the photovoltaic digital cat to the computer to test it and find possible problems. Take down the router first, then connect the optical modem to the computer, use broadband dial-up to access the Internet, and then check whether the network is normal, if it is normal, there is a problem with the router.

3.The last situation is that the router is placed too low, and everyone usually puts it on the computer desk or hangs it up about one meter from the ground, in this case, it is difficult for its signal to diverge. I suggest that you put the router on a higher place, such as above the wardrobe or about two meters above the ground, and be careful not to stick it on the wall, as the signal will also be affected if it is pasted on the wall.

If there is a problem with the router, it is generally due to its poor performance, or the situation of wifi co-channel interference. Whether it's an office or a home, the router is on 24 hours a day, unless there is no power, otherwise the simple chain is basically in a state of continuous operation every day. In addition, some people will also put the router in a closed space, so the heat dissipation of the road pin bypass is not good, and the performance will decline after a long time.

What to prompt specifically. Whether you can't connect or can't connect to the Internet. You first determine the strength of your model. And set up your DNS in the trial. If it doesn't work, try it with other routes.

Specific problems need to be analyzed in detail.

1.First of all, from the computer|Management|Device Manager to see if the wireless LAN driver is installed correctly2If the driver is incorrect, you need to install the correct driver3

If the driver is fine, some laptops have a wireless LAN switch on the side, check if this switch is in the off position.

4.Check that the user and password for the wireless connection are correct.

5.Check whether the IP and DNS configured for the wireless network are set to static addresses from the Network Properties.

Is there a signal?

I just solved it. Is it the instability caused by IP conflicts (mine is with the iPhone at home), sometimes it should be able to get on, right?

Set a fixed IP and you're good to go.

Many users will encounter laptop network cards that can search for signals, and wireless networks can be used normally, but computers cannot search for signal prompts. So what should I do if I can't access the Internet with the wireless network card of the computer? Let's take a look at the solution.

1. Enter the key combination on the keyboard: win+r, open the running window, enter cmd, and enter the command prompt window.

2. Enter ipconfig release in the command prompt window, wait for the command to be executed, and then reconnect to the wifi.

3. After the wifi is connected, enter ipconfig renew in the command prompt window.

4. Network configuration: Right-click on the wireless network card and select "Open Network Sharing Center".

5. Go to the Network Sharing Center window and select "Change Adapter" on the left.

6. In the "Network Connections" window, find the wireless network connection.

7. Right-click on the wireless network and select "Disable", then select "Enable".

The above is the solution to what to do if the computer's wireless network card cannot access the Internet, as long as you follow the above steps, I hope it can help you!
