What should I do if Win7 System Device Manager doesn t have a network adapter?

The solution is as follows: copy a network card universal driver, install it on the computer, and then ** a driver life or driver wizard software, and you can get some uninstalled hardware driver information after running, take "drive life" as an example:

Second, the network card is faulty.

The corresponding solution is as follows: the computer with a separate network card can choose to replace the new card, if it is only an onboard network card, you need to shield the original network card in the motherboard BIOS, and then install the independent network card.

After starting, press the DEL key, you can enter the BIOS, check the Integrated Peripherals (green box) and press Enter, we can see the "OnBoard LAN Device" option, then press the page up or page down in the function key area, and finally select disabled.

First: It may be that the NIC driver is not installed, and the solution is as follows:

After starting, press the DEL key, you can enter the BIOS, check the Integrated Peripherals (green box) and press Enter, we can see the "OnBoard LAN Device" option, then press the page up or page down in the function key area, and finally select disabled. After the above operations are completed, the problem that the win7 system device manager does not have a network adapter is solved.

First of all, you need to adjust the network adapter, and secondly, check whether there is a problem with the network card, if not, you need to check the network card driver problem.

The detailed solution is as follows:

Method 1: It may be that the network adapter has been disabled and re-enabled, generally in the "Network" properties, and then in "Change Adapter Settings", find whether there is a local connection or wireless network connection that has been disabled (gray), and right-click the pattern to enable.

Method 2: If it is a laptop, check whether the wireless network is turned off, and the general wireless switch will be turned on on the fuselage or by fn+f.

Method 3: The NIC driver may not be installed.

Right-click "Change Computer" and then Properties, then open "Device Manager" and click Open.

Open Device Manager and find Network Adapter to update the driver.

The win10 system computer obviously has a wireless network card installed, but there is no network adapter in the device manager. At this time, you can generally reinstall the wireless network card driver, if this method still doesn't work, you can try to use the following method. I will introduce it to you below, and you are welcome to refer to and learn.

Network Adapter:

Workaround for Device Manager without a network adapter:

1. Check the hardware switch;

2. Check FN+F5 to see if the wireless network card is turned off;

3. There is no problem with the above settings, uninstall all the drivers and software of the wireless network card. Reboot, and then install the driver (in order to avoid the intel network card nerves, please customize the installation, mine is because of the missing wifi sta component, caused countless experiments);

4. If it still doesn't work after the previous 3 steps, please uninstall all the drivers and software of the wireless network card. Then shut down. Take out your Phillips screwdriver, open the cover on the hard drive side (the one under the touchpad), and remove the wireless card. Don't put on the back cover;

5. After turning on the computer and fully entering the system, directly install the wireless network card (be careful not to let the sweaty hands touch other hardware, otherwise the short circuit will burn out);

6. Close the back cover and install the driver.

The above is the solution I have sorted out for you win10 system device manager without network adapter, after the above operation, no need to restart, you can find the wireless network adapter in the device manager, I hope it will help you.

Win7 System Device Manager No Network Adapter, What's Going On? In the right case, open the win7 device manager to find the network adapter, the network adapter is the interface of the stool in the LAN to connect the computer and the transmission medium, if you find that the device manager does not have a network adapter, how to solve it? In response to this problem, two causes of failure and solutions are summarized, and if you are interested, you may wish to take a look together.

1. The NIC driver is not installed

Solution: If there is no suitable driver file in the system driver installation package of the computer, resulting in the network card driver failure to install, and you do not know the model of the network card, you can copy a network card universal driver from other places to install. After the computer can access the Internet, then install the "driver wizard" or "drive life", run the software to scan and install the inappropriate and uninstalled hardware drivers, take "drive life" as an example;

Second, the network card is broken

1. If the NIC is damaged, the NIC cannot be found or the NIC driver fails to be installed. If it is an independent network card, it can be solved after replacing the new card; If it is an onboard network card, you need to enter the motherboard BIOS to shield the original network card, and then install an independent network card;

2. Press the del button to enter the BIOS at boot, select IntegratedPeripherals (green box), press enter, you can see that there is an OnBoardLanDevice in it, press the pageup or pagedown in the function key area, and select disabled.

The above is to solve the problem that the win7 system device manager does not have a network adapter, if the network adapter fails, it cannot connect to the network normally, you can follow the above two methods to set up.
