Most of us have ever faced network adapter driver issue on Windows 7, 8 or 10, which can cause some network connection problems. It mainly attributes to a lack of network adapter driver, the driver is outdated or it's incompatible with the system. The problem is common when you update Windows systems or have ignored to update the network driver for a long time.
In this case, what we need do first is to check the condition of the network adapter driver on your computer.
Step one: "Win+R" and input "devmgmt.msc" to open up your Device Manager, and you will see there is a yellow triangle with a question mark (my network adapter driver is fine, so there is no alert in the picture).
Step two: Right click the network adapter driver and you can choose uninstall or update the driver. However, due to no network connection available now, update the driver can be non-sense. Take Windows 10 for example.
For this problem, no matter you are using Windows 7, 8 or 10 system, you need to update your network adapter driver or re-install it. There are several steps we can do to get effective solution.
Step one: Since you have uninstalled the network adapter driver on your computer and you cannot connect a network, you need to use another PC to download a new driver, then save the install program in your USB. Please pay attention to the compatibility so that it can perform well on your computer.
Step two: Install the driver you have downloaded on the official website and see if there is any problem. Generally, after installing or updating the network adapter driver successfully, the computer can be connected. If not, please restart your computer.
How to avoid the problem efficiently?
Most of the time, we don't know the exact condition of the drivers on our computer. And it's impossible to check them every day manually. So regular check is necessary.
