NETGEAR_Nighthawk X6 R8000 is my router.
However, this laptop travels extensively and the problem is present everywhere. Even here in trying to diagnose I have plugged in a usb adapter, TP-Link TL-WN22N, and turned off the internal card. Although the external adapter doesn't spontaneously disconnect, it often fails to automatically connect on boot, for what that's worth. Thank you for your interest.
