View RaspberryPi 3 Retropie OS Wifi using DHCP with DNS and Gateway in different devices
The main three things are these:
1. Inside /etc/network/interfaces:
The wifi interface should be set as dhcp as have the usual settings for using wpa_conf
2. Inside /etc/dhcpcd.conf:
Disable ipv6
Add the the gateway (router) as static routers=...
3. Create a file /etc/sysctl.d/40-ipv6.conf, where you disable ipv6 for all AND for each interface
(more info about ipv6 disabling in https://wiki.archlinux.org/index.php/IPv6#Disable_IPv6)

There are 3 ways of disabling power save on the Raspberry Pi 3 depending on how you wifi is configured:
1. Configured using NetworkManager
Follow this gist: https://gist.github.com/jcberthon/ea8cfe278998968ba7c5a95344bc8b55
2. Configured using Command Line editing `/etc/network/interface`
The accepted known method is to add the following line *AFTER* the setting up of the interface
