What do you mean delete wifi link completely? Just remove my wifi connection at home? I want to remove it completely so at a friends house they don't add it by mistake.Might not be good for the circuitry on the motherboard. Best to just keep on Airplane mode, or just delete your wifi link completely from the Switch wifi settings.
Kids probably, it's always those damn kids! That way they (or the dog/cat) can't connect to wifi, and "accidently" update it.
