Wireless adapter keep disconnect after a while

Hi, I' m using Dell inspiron 3543 ( Windows 10 64 bit lastest build without insider program). Recently, I have a problem about wifi adapter, it keep disconecting while i'm using and I can't re-enable Wifi (when this happen the Wi-fi list empty, there no way to fix but restart laptop even sign-out won't work). I don't know what cause this problem, software, driver, windows. I didn't have installed any VPN program, just clean laptop with basic program (recently reinstall OS).
