WiFi and bluetooth functionality (possible controlling) gone from Windows 10 Home on laptop

I own 7 years old Toshiba Satellite C850 19Q laptop and it is in very great condition, now let me tell you some story. I use the laptop for gaming and since for gaming the direct connection to internet is the best choice, ofc I was connected via cable, so I wasnt able to notice that Wi-Fi support is gone from my laptop, so I realized that after cleaning dust from inside, when I turned it up and making sure that everything works just fine, then I noticed that Wi-Fi doesnt work anymore. I tried all the methods recommended when the functionality is gone but nothing good, now Im about to buy a new Wireless card, but how can I make myself be totally sure that I wont just pay and then discover that there is other issue and wireless chip change does have not any effect. Im asking this, because Im young - 13 years old and Im not rich, I dont get a lot money as pocket so I need to invest carefully, since the chip costs 40€ and so I get only 5€/week. So please dont down vote for this :,(

Edit Also wanna tell you, that all the options and functionality of wifi is gone from windows (10 home activated x64), I can only see about wifi - its properties in settings, device manager and somewhere in control panel

EDIT So I have replaced the wireless chip and nothing changed, so now the objective is to discover why windows 10 doesn't let me fully use bluetooth and wifi. Idk, I'll give as much info as i can; - 30GB free on WD Blue SSD (500GB) - 8GB ram (2x4GB) - Wireless chip - Realtek / Broadcom - GPU Amd Radeon (1GB) + HyperMemory - CPU i3-2328M - 2x 2.2GHz, no turbo, 2nd gen

Solution 1:

You may be able to re-establish the wireless features of your wifi card by performing a few steps.

Open the device manager and select the wifi card. Right click on it and use the Uninstall option. DO NOT select the "delete files" option. It will be un-selected by default.

Complete the device uninstall and reboot the computer.

You should see an indication that new hardware has been found and that the system is installing the device drivers for it.

There's a strong possibility that this will restore functionality to your wireless. I have had to do this for clients' computers in the past, not only for wireless but sometimes for video drivers and sound drivers.
