I'm on a Asus VivoBook S14 430FA.
It has a Realtek 8822be. My connection is 100 mbit/s but my device gets only 12mbits down and 4mbits up. It's getting -81dbi connection strength even though my WiFi route is just 5 meters away.
Tried kernal 4.4.19 and now on 5.1 but still no improvements, on Windows 10 it gets 40-70mbit up/down.
here's pci-e card info .
