I found a bug and have any idea what to do. I have tested it with Windows 7, Windows 10 and Linux Mint 19 with different cases.

I have BIOS ver.1.32, OS Windows 7, Windows 10, Linux Mint 19, SSD with GPT (MBR before) with solo and dualboot.

Problem: when i loaded OS - my ethernet network card not working properly and not automatically setup. No matter what OS i have - it affect any if triggered. OS show that my connection cant setup and try again and again. Switching it off and on, card as device - not helping. ISP have auto DHCP so all what i need to do - just set auto everywhere and plug the cable. Card detect: cable plugged in or not, but not connect after.

First time i can see this bug after BIOS update and installation of second OS. Something it triggered before any OS loaded and after that i have non working ethernet card. Also if i use only one Windows without switching - card working fine but any moves with BIOS or disk partitions - and goodbye my ethernet connection. Linux also do something (maybe ask a time) and triggered this so for linux it's a 50\50 chance to lost ethernet as connection.

I can return connection with random chance if change any settings in BIOS and reboot then.

Acer know about this?
