Fix Wifi Lag on S7

Automatic

Set DNS as google using DNS Changer

Manual

Enable Developer mode on your S7 or S7 Edge.

In the new "Developer options" in "Settings" change "Use legacy DHCP client" from OFF to ON.

Anothery Way

Change DNS settings

If the above tips did not work for you, its time to take things to the next level. If the Galaxy S7 is the only device in your Wi-Fi network to suffer from slow speeds, you can try changing the DNS server used on the handset.

For this, you will first have to make the device forget the existing Wi-Fi network. Then, tap on its name to join again, but before you enter the password, tap on ‘Show advanced options.’ Now proceed to tap ‘IP Settings’ and select ‘Static’ from the list. Leave other IP settings as they are, and simply enter the DNS server you’d like to use in the DNS text field area. You can try using Google DNS first (8.8.8.8, 8.8.4.4) or OpenDNS (208.67.222.222) to see if they fix the Wi-Fi woes on your S7 or not.
