I go the same issue with the same adapter, but different notebook (Alienware in my case).
My notebook drop connection and reconnect to network exactly every 180 seconds. Router logs shows station-initiated disconnect.
I din't find any related timeout at router and driver settings.
Windows 10, 1909
Driver 220.127.116.11 (but issue have place at older/Killer ones as well).
