Suddenly No WIFI connections and Bluetooth

This problem occurs unexpectedly. I usually use my laptop to connect to WIFI in our school then suddenly i cannot detect any wifi connection even bluetooth disappear. What is really the problem? I've been searching for a solution in about past weeks. And i'm so thankful if someone would help me in this problem. THINK POSITIVE!

here are the evidences:

Deborah, it appears you are in airplane mode. Have you clicked on the button to see if it will turn off or is it stuck on?

Welcome to the forum!

thank you for welcoming me. Well I already turned off the airplane mode and there's no change at all. I can't turn the WIFI on/ off even i tried alot of times switching the wireless switch and typing FN+F5

OK, what is that Other Devices with the question mark at the bottom of the picture you posted?

You have a lot of missing drivers. What make/model of computer?

i do have a lenovo z470.

I don't know, the driver page on Lenovo page is a hot mess. Do you have a restore point before this started?

the restore point is not working thank you for trying to help me and if you have any solution to this problems please let me know.

Short of a system refresh all I got left is uninstall everything with the yellow triangle, and uninstall all your network adapters then reboot. See if it installs things properly and wifi works.

EDIT: Wonder if a recent Windows update caused this. Also, you need to figure out what that second display adapter is and install the correct drivers for it.
