    May be you can get a Recovery Media of Win 10 and reinstall the OS and check, if still have issue than contact Acer support.

    @Srijansm was it working fine before ??? if so seems to me that you might have a faulty wifi adapter not recognized by the mobo (its rare but might happen) if youre able to disassemble it and try to clean the pins and reconnect it if the issue persists its most probably what i just said good luck :)

    If you are not able to see the bluetooth and wifi adapter in device manager doing power drain and bios defaults will really help to bring the adapter back on device manger.. 

    Doing the power drain and bios defaults will really help.  Kindly follow the steps given below:


    Turn off the laptop. Disconnect or unplug  the charger cable, devices or any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, you can find a  pin hole. It is a tiny hole. You can a find a battery symbol indicator next to the hole. It is like a + and - sign symbol as though somebody is trying to shift the battery out. Insert the pin on to the hole for 30 seconds. Remove the pin. Flip the laptop. Connect the charger cable, turn on the computer.  Only on laptops where the battery is inbuilt you can find the battery reset hole on the back of laptop.


    If you dont find a pin hole on the back of laptop then you might be using removable battery. There is no need to unscrew anything to remove the battery.  Turn off the laptop. Disconnect or unplug  the charger cable, devices and any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, please look at the top or bottom depending on the way you look at it. You can find a long door. It is a battery removable door.  Just below that you can find a latch.  If you move the latch you can remove the battery door. Once the battery is removed,  flip the laptop. Open the top cover, press and hold the power button for 1 minute. Connect the battery back on the back of computer. Connect the charger cable back and then turn on the computer. 

     

    If you don’t see a reset pin hole on the back of laptop or if you are not able to remove the battery (if it is inbuilt ) then please unplug all the cables and devices out of laptop.   Hold the power button for 1 minute.   Connect all the cables back and restart the computer.  



    While turning on the computer, tap f2. It  will go to bios. Press f9  once. It will show load bios defaults with a yes or no popup. Press enter. Popup screen will disappear.  Press f10 once. It will show save changes popup with yes or no. Press enter. Computer will restart and it will load into windows.   


    Please check in device manager now..

    Yeah usually a powerdrain will solve most issues (that arent hardware related) but i would leave it to rest at least 1h after a powerdrain and to make sure would disconnect the battery and the rtc battery completely from the mobo for a proper powerdrain :)
