As you can see from the diagram, your computer has not detected a working wireless network card at all, and it is certainly impossible to detect a wireless network.

One possibility, is that your wireless network card driver is not installed, another possibility, is that the wireless network card has a hardware switch, now it is off, it is recommended to check.

The problem is that there may be a problem with the driver on the hardware or it is missing, why? Because the laptop is a network card used by the mobile king card, if the driver is lost, he will not work properly or just stop working, then it will not work if you take it out. So when installing the driver, you remember what model your king card is, and reinstall the driver next time there is a problem, or back up the driver on your computer.

It's best to install Master Lu's software on your computer. It can help you find the drivers you need, and it can also be backed up, and the next time something goes wrong, click Master Lu to reinstall it and complete the task.

Could it be that there is a problem with the network card driver?

When using a computer, sometimes you find that your computer network only has Ethernet and no wifi, what is going on? How to solve it? (At present, there are many users using win10, I take win10 as an example).

1. Update the driver.

1.When win10 has no wifi and only ethernet, the most likely problem is that the driver is not updated. Although win10 itself will automatically install the driver,But in many cases there will be problems with this function,At this time, you can directly enter the windows update settings in the search function in the lower left corner of the desktop。

Turn on the function, select Windows Update to check for updates, and the system will automatically install the latest version of the WiFi driver. Win10's wifi feature will be back.

2.In addition to using the system's own driver, users can also use the driver software to update the driver, the commonly used driver software is Master Lu, the driver wizard directly in the driver update to see if there is a network card version can be updated, directly update it.

2. Whether the wifi function is disabled.

Now many keyboards come with a one-click disable wifi function, users only need to turn on the wifi on the keyboard to successfully solve the situation that win10 has no wifi only ethernet. 3. Other diversified network settings.

If both of the above methods don't work, then restoring your computer's network settings directly will help you solve all of them. Enter the key word network reset in the lower left corner of the desktop in win10,Then click Reset immediately,After the system reset is completed, the wifi function will come back。 If the above measures are useless, it is recommended to find a technical professional computer master to view, it is likely that the hardware problem causes your win10 to have no wifi function.
