What should I do if my laptop wifi light is no longer on?

What should I do if my laptop wifi lights are not on? I am not doing anything today, resulting in wifi and so on. The Fn + F3 key is difficult to use, and the driver is okay! No wireless devices found in the cracked version of www.2cto.com apwifi! I am in a hurry. What is the situation! I was planning to reinstall the driver, but I still don't know how to update it when I look at several drivers. One of them is wireless, which should be the wireless network card! Update it. Open the Device Manager and update the device online. A prompt will be displayed later. The driver is the latest and does not need to be updated! Where is the problem? Www.2cto.com: Check the driver information of the normal Nic. The driver information of the wireless Nic is disabled! Enable the device! OK. startup successful! Fn + F3: the light is on! Haha, that's okay! My camera is probably the same problem. "No camera device is found" may also be disabled in the Device Manager! Solution! ----- The verification is true. It turns out that the camera is disabled in the Device Manager! , Learned a trick! Haha, happy
