How do i play online on survival mode with my friends?

First off, I'd like to remind you that this website is for bugs and not help guides, but you're lucky because a help guide, which is me, came along and is now going to help you!

Step 1: Go to the settings app. Step 2: Turn wifi on and bluetooth off.
Step 3: Make sure that all devices that will be used for multiplayer are on the same wifi. Step 4: The host must enter a saved world and allow others to join via the settings menu. Step 5: Connect all devices to the server. Step 6: YOU ARE COMPLETE!

@unknown and on pc? Is it the same thing(except for bluetooth)?
