Hi, I am using Acer E5-473G which originally comes with Windows 10 OS. Unfortunately  was forced to reformat my laptop and have it downgrade to Windows 7. I already downloaded the drivers but sadly, my wifi is not detecting any connection and my 2 USB Port (Which I believe 2.0) are not working. I already tried checking the driver through device manager and also used driver scanner/installer but still not working? Do you have direct solution on this? Thanks in advance.
