Help Setting Up a Static IP Address

What’s the best way to set-up static ip?
(I tried doing it by myself and I ended with network that I was not able to use)

@Shad0w Without seeing the router setting myself it is difficult to tell. But I did find a video on youtube that is easy to follow along with. https://youtube.com/watch?v=qA73fxyX9Nw Hopefully this points you in the right direction.
