Is this happening when directly connected via ethernet cable? Might just be your laptop WiFi adapter. Also in Windows 10, some power management settings have been interfering with WiFi sleep settings, disabling the adapter after a while.
Not having any issues here, loving this phone. I would guess it might have something to do with your in home network? Are you in a congested environment for WiFi and are you connecting to the 2.4 GHz frequency on your WiFi?
Try connecting to the 5GHz frequency if your access point supports...
