I've seen some improvements after adding "ScanWhenAssociated". It seems like the big dropouts like seen on the picture below mostly occur when I'm streaming to twitch (upload) and when using VPN connection to my work (only rdp connections, no heavy data transferring).
I have tried the following drivers so far, every single one of them does not correct the dropout issue
"lenovo driver" version 17.12
version 16.x.x.x
version 17.1.0.19
In addition I have tried the version that came as default with windows (can't remember the version number, but I think it was 1 year old or so).
I've also tried to set up a new SSID with only 2,4 ghz and another for only 5 ghz -> problem still occurs on both these SSID as well.
So far I've gotten much better help from you guys then I ever have received from Intel, mostly appreciated. I'm not even sure if I should bother ask them because I know that they simply will point at my Aruba AP, even though my surface pro 2 does not have this issue. neither does my old 15$ go-usb-n150 I used on this same computer before I bought the Intel card.
NOTE:
It's not unusual that I get this result as seen below now, but I still get huge dropouts as seen above
