Acer Laptop Downgrade, Cannot get any LAN/WIFI Drivers  

I've got Acer E5-521. It's the same model.
The TS was able to find the solution, I wasn't. He got help, but he was too lazy to share his solution. That's what I was angry.
Now it doesn't matter, because I've gone and got a Wi-Fi adapter.

You must have skimmed over this bit,

We have wireless!!!! Again, with your wonderful tip of going to details, hardware ID, I could see it was the atheros. so that has installed now as well.

Using this method you could find out what driver you need,

Hardware Identification

There was a chipset driver mentioned as well.
