Windows 10: What to do if my WiFi isn't appearing?

Few days ago, my laptop's WiFi has been disconnecting then it disappears suddenly then appears. It continues to do so. But just now, I updated my laptop according to the Windows' update, I'm a student so I don't really know any of these. Then, I can't connect to my WiFi and Bluetooth, The Airplane mode isn't working also. I searched for any solution I find and ends up deleting the driver for my WiFi. Is there any way to get it back? Also, how can I fix this problem? Please, help me. I need my laptop to be fixed.

Printer isn´t working after latest update.

After the latest update from Windows, my Canon Pixma ip6600 printer isnt working. In Device Manager it shows up as working properly but when I go to print it isn´t listed as an option in any programs. Troubleshoot suggests it´s a USB 2 printer on a USB
3 port and that that´s the problem but that cant be since it worked fine before the update. I´ve tried to uninstall and plug it back in but that doesn´t work either.

 

Cortana isn´t working

When I hit enter, it did something, but there´s still no Cortana, even after restart. So I tried it again, but now it says that it failed, because it´s already installed and it´s working in PC. So it should work, but Cortana still isn´t here.

 

Printer isn´t working after latest update.

Managed to solve it... here´s how I did it just in case anyone else has the same problem...

->Settings

->Printers & scanners

->Add a printer or scanner

->The printer that I want isn´t listed

->Add a local printer or network printer with manual settings

->Use an existing port: USB001 (Virtual printer port for USB)

->Choose printer

->Use the driver that is currently installed

->Type printer name

And done... =P
