Galaxy S6 wifi tethering not properly working on win8-laptop

A

AC Question

The internet connection occasionally (but frequently) drops: the laptop shows "limited connection" for couple of minutes, and then the connection starts working again...

The laptop works fine in every other wifi-networks (including connections shared from another phones). My Galaxy S6 mobile hotspot also works fine with other devices and laptops...

In win8, Ive already enabled "download over metered connections" and disabled the "turn network adapter off to save power".
