Error Code: NW-31291-6
I’ve tried restarting both router, modem and PS4.
Internet works great on my phone and laptop.
Router and modem placed ca. 21 feet from PS4, tried multiple placements with no result. Router and PS4 is updated to latest firmware (2.03 on the PS4).

All it says is “Cannot find the Wi-Fi-network. Wi-Fi-Networksignal could be weak or SSID could be wrong (NW-31291-6)”

Help Please?
