I have the above mentioned Swift 3 Kaby Lake (i3). I had some disconnecting issues with WiFi on BIOS 1.01 that the laptop came with. Acer webpage suggested BIOS 1.08 according to my product SNID 65101294372 and I installed that. Now WiFi issues are more frequent, some trouble with headphone jack and Adobe Flash issues (crashes), too.
Could you at Acer verify that I am using the correct BIOS?
