Asus PCE-AC68 lagspikes

[nospherato]

Hi everyone,
I am facing a strange problem for a few days now:
I did not change anything in my Win10Prof but my pce-ac68 seems to get lagspike every few seconds.
It looks like this:

ping 192.168.1.1 -t

First I thought it's the new ddwrt version for my rt-ac87u, but I get the same spikes when testing ping to my neighbours wifi...

The strange thing is, I can reproduce these ping spikes just by clicking on the wifi symbol in the task bar (click it, it searches for wifis --> bam +100-200ms).


I already tried:

- Every driver version found at the asus homepage (win7, win8, win 10) and the drivers found here in the windows 10 thread from broadcom
- Disabled my bluetooth headset (pulled the adapter from usb)
- Disabled alls PCIE powersavings
- Tried different advanced settings (disable beamforming etc.)
- Disabled auto-discovery for wifi
