Losing internet connection after idle time

[ifrazzreal]

Everytime I go afk for like 30 minutes, my computer disconnects from the internet. I searched it up on google and they say "power management" under device manager under network adapters. They say it should be one named 'Realtek' or something like that. When I go under properties, all I see is
General,Advanced,About,Driver.

This is some info about my pc.

I FOUND THE SOLUTION! YOU HAVE TO UPDATE THE DRIVER BY RIGHT CLICKING ON IT AND HITTING "UPDATE DRIVER".
