After updating my computer, the login screen appeared and after logining in my screen was black. It didn’t show my background picture or my icons. It only showed my taskbar below and indicated that my computer was “not connected - no connections are available”. After proceeding through the troubleshoot problems it reported that there might be a problem with the driver for the Wi-Fi adapter and a network cable is not properly plugged in or may be broken. How do I fix this?
