So I accidentally deleted my network drivers, which then correlated to my network controller not being installed. I can't reinstall or find the issue because I have no possibilty of reconnecting to my wifi. Im confused I've reset multiple times and still can't find a way to fix my network issues.

    If the Wi-Fi or network controller driver was removed, the practical recovery path is to install the driver offline from another device.

    1. On another PC with internet access, download the correct network adapter driver from the PC or motherboard manufacturer.
    2. If the download is a .ZIP file, extract it and copy the driver files to a USB flash drive.
    3. Make sure the .inf file is in the root of the USB drive, not inside a subfolder.
    4. On the affected PC, plug in the USB drive.
    5. If setting up Windows or working from setup, press Shift + F10 to open Command Prompt.
    6. Run: 
         diskpart
   list volume
      Identify the USB drive letter from the Ltr column.
    7. Install the driver with: 
         pnputil /add-driver D:\*.inf
      Replace D:\ with the actual USB drive letter.
    8. If needed, run: 
         pnputil /scan-devices

    If the driver package is an .EXE instead of a ZIP, it may install by simply running that file from the USB drive.

    If Windows is already installed and Device Manager shows the adapter under Network adapters or Other devices as Network controller, another supported option is:

    1. Open Device Manager.
    2. Expand Network adapters.
    3. Right-click the problematic wireless adapter or network device and select Uninstall device.
    4. Select Delete the driver software for this device or Attempt to remove the driver for this device.
    5. Restart the PC.

    If the driver still does not return after restart, install the latest wireless or network driver from the device manufacturer using the USB method above.

    Hi, Nathan Pham

    The yellow warning beside Network Controller means Windows detects the hardware but does not currently have a usable driver. Repeated resets may not restore a driver package that was removed.

    Besides the solutions provided by the Q&A Assist, here are some suggestions you can try:

    Use System Restore to return Windows to a point before the driver was deleted. Press Windows + R, enter rstrui.exe, choose Next, select an earlier restore point, and finish the restore. Personal files are not removed, although recently installed apps or updates may be affected.

    Temporarily connect the PC using an Ethernet cable or a USB-to-Ethernet adapter. Another option is connecting an Android phone by USB and enabling USB tethering. This can provide temporary internet access without the missing Wi-Fi driver.

    Once connected, open Settings > Windows Update > Advanced options > Optional updates > Driver updates. Install any wireless, LAN, chipset, or network-controller updates shown, then restart the PC. Optional driver updates are not installed automatically.

    If no driver appears, check whether the wireless adapter is enabled in the computer’s BIOS/UEFI settings.

    Thank you for your patience in reading, I hope this information has been helpful to you.
