I have the same issue with Wifi dropping on some occasions (especially when using Wifi hotspot on my smartphone). I have i3 (Kaby Lake) 8GB/256GB. My BIOS is version 1.01. Is there a more resent BIOS for Kaby Lake Swift 3 or is the 1.07 for Sky Lake only? Acer Care Center cannot find any updates...
I will try the High Performance setting next time when connecting to smartphone hotspot...
