WiFi is Disabled
Many laptops have a physical switch or a function key (such as Fn + F2) that can toggle the WiFi adapter on and off. If this switch is turned off, the WiFi adapter will not be detected by the operating system, leading to no WiFi options being displayed.
Install any missing device drivers. A missing network adapter driver could be the reason you can't see your Wi-Fi network, but this is almost always a problem only if you just recently installed Windows. If the wired network doesn't work either, you'll need to use a working computer to download the driver.
