Windows 10: Laptop wifi won't work?

Hello, with my laptop the Wlan simply cannot be switched on. Before everything went fine, then I changed the Wlan and it doesn't work anymore. Is an Acer device with Windows 10, do I have to do something in the device manager or similar? Thanks in advance.

P.S. Windows 10 was probably installed afterwards, because there is a Windows Vista logo on the device.

Windows 10 Wifi Won't work

I tried all these suggestions & my wifi still won't turn on.

My wifi works on an older computer that doesn't have Windows 10. So it's a problem with the system,

I need help. Next step is buying a new computer.

 

Best laptop under $800??

Well the last one I suggested seems to be the best for 650$

Windows 10 wifi not turning on Acer Aspire laptop

In order to get the list of available wireless networks, you have to:

1. Switch on Connect to suggested open hotspots (see the screenshot in question);
   
2. Click on Wifi icon in the right corner. Now you have your networks back.
   

After that the parameter from Step 1 can be turned off, networks will be listed normally after restarting Wifi.

P.S. I feel rather stupid at the moment. I thought that open hotspots are passwordless hotspots and so are presumably not very safe. So of course I've turned that off during installation.
Really hard to see any logic in this case.
