We are only a few days into the latest major software update for the PlayStation 4. The PS4 system software version 4.50 adds a handful of new features for the console like support for external hard drives and a Boost Mode for the PlayStation 4 Pro.
However, it looks like there are some bugs as well. Some PlayStation 4 owners are reporting that their consoles can’t connect to Wi-Fi once they have been updated to the new update. Has this happened to you?
Many reports have surfaced online about updated PlayStation 4 consoles being unable to connect to a Wi-Fi network. More attempts only bring up the “failed” notification when trying to establish a connection. This is frustrating for PS4 owners. Some owners have also reported that their Wi-Fi passwords are being rejected as incorrect and getting the error code NW-31297-2. Even though they know their Wi-Fi passwords are fine.
You can always hook up the console to an Ethernet cable for internet access. Others have removed the password from their Wi-Fi networks in order to get the console to connect. Sony hasn’t acknowledged this issue yet, but they are surely working on it. They don’t want irate gamers.
