Wifi and Bluetooth issues

Hi From yesterday afternoon my WiFi is not working, so first I thought it would be a normal driver problem and installed driver but got a error message (cannot start the device (errror code 10)) After installing drivers also I had the same problem So I clean installed the windows is and still the issue persist but now the WiFi adapter is not in the device manager itself and I checked in bios to verify whether it is a os problem and the bios also failed to recognise it My WiFi adapter had a problem of disabling automatically sometimes and re-enables after 15-20mins (it doesn't show any networks or connects) But after clean installation the WiFi is not even showing up in the device manager I request you guys to please help me Laptop: dell inspiron 3511 WiFi adapter: Realtek rt|8821ce WiFi adapter I also don't have a Ethernet port

Please help me fix it
