Lan cables use at ps4 pro?

I have just set my ps4 and would like to download fortnite. This takes an abnormally long time so I asked my friend if this is normal. She said with lan cable it would be ready in 10 minutes like her and her brother. Since I use but now when setting: Use Wi-Fi network factory, I've asked myself if I can change this to LAN cable because I want to get one with tomorrow.

Which gamer uses WLAN please? Wired is always better and faster. And clearly you can change that
