Laptop just does not connect to the Wi-Fi?

My laptop does not connect to the Wi-Fi, my cell phone and my sister's and everything else but already. I have tried very often to disconnect and restore the connection, but each time there's just "no internet, secured". I've also restarted it 3 times - and nothing happens.

What should do?

Do you happen to set up a MAC share and your laptop is not there yet?

Some laptops allow you to enable and disable the network connection using a shortcut key. For this you usually press the FN key and one of the F-keys. Just let's see if there's a Wi-Fi icon on any of the F-keys or anywhere else.

Otherwise reset the network settings of your device. Open the Command Prompt (cmd) as administrator and execute the following commands:

netsh winsock reset
netsh int ip reset
ipconfig / release
ipconfig / renew
ipconfig / flushdns
netcfg -d

Then restart your laptop.

If the problem persists after that, you will most likely have to adjust something in the router interface. Maybe there's a list where devices have to be approved first.

Go to the folder drive C (hard disk)

then context menu (right mouse button) on properties

then go to Tools and Error Check - Check.

If there's an error in the system, Windows will correct the error.
