Usually, when you turn on your computer, Windows 10 automatically connects to your default Wi-Fi network. However, at times, Windows 10 might not automatically connect to your Wi-Fi network even if you have configured Windows 10 to automatically connect to a specific Wi-Fi network. I had been experiencing this issue on my computer running Windows 10 version 1903. After a lot of trial and error, I managed to fix the issue. If your Windows 10 PC is also failing to automatically connect to a Wi-Fi network, you can try out the given below troubleshooting tips to address the issue. Check if the Wi-Fi adapter is being turned off to save power There is a provision to automatically turn off the Wi-Fi adapter when Windows 10 is idle for some time. This usually prevents Windows 10 from automatically connecting to Wi-Fi network upon turning on the PC. Here is how to fix it: Step 1: Right-click on the Start button on the taskbar and then click the Device Manager option to open the Device Manager window. Step 2: Here, expand the Network adapters tree. Here, right-click on your Wi-Fi adapter’s entry and then click Properties. The adapter’s entry usually includes Wireless Adapter or Wireless AC in its name. If you are having trouble in figure out which is your Wi-Fi adapter, refer to your computer’s manual or specs sheet. Step 3: Switch to the Power Management tab. Deselect the Allow the computer to turn off this device to save power option. Click the OK button. Restart your computer.
