You didn’t mention the requirement to use WiFi in your OP, or any other post, so why would someone link that for you? You are getting upset with people offering help when you haven’t provided all the variables of your equipment or use case scenario.
It isn’t included in the instructions as it isn’t a recommended way to run HA.
These instructions should help you setup WiFi.
If thrusting your hips in the air in a sexual manner while angrily repeating something ad nauseam is something that you feel is more beneficial, then perhaps HA isn’t for you.
You aren’t helping yourself by being so adversarial. You come looking for help, people are trying to help you. Stop throwing mud.
