Frequent disconnects

Can anyone help? I have this new wi-fi adapter and it continually drops service.  No other devices on the home network drop service- just this new one.  The only way I can get this computer back up is to do a re-boot.  I've power cycled the router, and I keep getting the same result.  Very frustrating!  I'm not a tech expert, so please walk me through what I need to do to make this thing work properly.  We are running Windows 10.
