Windows 10: Wi-Fi won’t turn on

The Wi-Fi on my sisters laptop turned off by itself and won’t turn back on, she restarted it multiple times and it still wont work. There is no option to turn it on and troubleshooting does not work. How do I fix this? Other devices in the household do not have this problem.

Trouble Changing Wi-Fi Password


I've been following the following steps to change my Wi-Fi password for some time:

1. Launch Control Panel.
2. Click "Network and Internet."
3. Click "Network and Sharing Center."
4. Click "Wi-Fi...."
5. Click "Wireless Properties."
6. Click the Security tab.
7. Check "Show characters."
8. Enter the password in "Network security key."

Those steps have been working just fine, but today I discovered a new wrinkle. If I change the password inside the router first, "Wi-Fi..." doesn't appear in step 4. This isn't much of a problem at home, because I can just change the password in Control Panel before I change it inside the router, but it would be a problem at a public hotspot, or something of that nature. I also tested Brink's instructions in "How to Connect To a Wireless Network in Windows 10," but they don't work for me either. How can I fix this?

 

Cannot turn on wi fi

I just reset a Dell laptop for the 3rd time. For some reason I cannot connect to my wi fi network. When I go into Settings and Wi Fi, the option is to manually turn on the wi fi and the "On" slider to turn on the wi fi will not stay "On"....it just keeps
sliding back to "Off". I have run numerous diagnostics and it will not even recognize my network. Any help would be greatly appreciated. I am frustrated beyond belief...saw the same issue on this Forum and followed the suggestions and still cannot manually
connect to the wi fi netowrk.

Thank you so much in advance.
