Drivers for Aspire E5-573G

Hello. I am Christine. I am currently having problems with my new Acer Aspire E5-573G-74AK. I have downgraded the Windows 8.1 to Windows 7 professional (32 bit) because one of the software that I need to use in my work does not work on windows 8 and 10.  The main problem is I cannot find the right drivers for the Aspire E5-573G and I cannot connect it to the internet using LAN or Wi-Fi.

No Drivers

Thanks.
