last week, i bought an acer e5-571g the touchpad is working. but i want to install synaptics or elantech to scroll with two fingers i tried to install these two programs from the cd( it doesn't work) i also install them from acer website and from synaptics website it doesn't work also.(i tried this with windows 8.1 and windows 10).
I also have another problem: the wifi suddenly becomes limited with that yellow triangle and return normal after few minutes, at the same time the Internet normally works with the smartphone (I reinstalled windows10 but the two problems are not resolved)
