I have an ASUS X556UR notebook connected to a home WiFi. Everything was fine, apart from rare disconnects (computer losing router, which I thought to be signal stength/distance issue at the time). However 2 weeks ago my internet got a lot worse. Basically now I have occasional 2-7 seconds ping...

I am on a hunt for the cause of HIGH DPCs. I systematically disabled services until my DPCs were absolute max 643us. They had been around 9ms max. The service was POWER. Can anyone rationalize this for me? What does POWER do? It doesn't seem to have any dependencies or needs. All I could find...
