Your networking driver seems a tad old for a Z-170 system. Try updating your motherboard drivers.
Also, as you have if you have tried a bunch of things please list them - anything else is just a waste of time.
And yes there's some people having issues with the game, but not that many actually considering how big the launch is. BF4 was like 20 times worse. All games will have some users that have issues, you can't avoid that.
I'm using a D-Link WiFi Adapter using the latest driver from their support site, and my Killer Network Driver is the most recent for my motherboard, (2015-10-06). And no, I'm not using a Z-170 motherboard, this is a B150 motherboard from MSI. https://www.msi.com/Motherboard/support/B150-GAMING-M3
In addition I made sure to monitor my computer while playing Battlefield and my CPU sticks to a ~75% of usage and maintains a 58°C while playing. My GPU coincidentally also sticks to a maximum of 58°C which is very good.
Tried out the new game-ready driver compatible with Battlefield 1 and unfortunately I can't notice any difference. I'm gonna conclude this as being a normal Dice problem and just wait for a patch addressing this. Until I guess I'll just keep the game on Medium settings, which is quite annoying having an expensive setup like this.
