Hello, I have two PS4 consoles, one purchased on the day of the premiere connected to the Internet via wifi on the connectivity test shows a download of 9.8 mb / s, a new one which I bought in a slim version that stands exactly in the same place max 500 kb / s (and sometimes drops to 9kb / s which makes doing anything in the ps store impossible). What could be the reason ? I reset the router and it did not help, DNS settings did not help either.
