Up until a couple of nights ago the wifi worked fine on both the Sony TV and both the ps4/ps5. At the moment all three devices are refusing to recognise the wifi, although every other device that is connected to the wifi is working fine.
We have tried cycling both the modem and the nbn router and hard resetting the products but nothing seems to be helping them pick up the signal.
Let us help identify what causing issues with the connection. When you try to reconnect the affected devices did you get any error message? Is the Wi-Fi network showing on your playstation?
