Can you access the recovery menu? (Press the power button while the PS3 is standby, Then keep the button pressed until it powers off again; Press again and keep pressing until 2 beeps occur, Then once those 2 beeps happen, Release your finger immediately then you're done.) I'm not sure if any of the options available will help you with that one error but you could try that.
Other than that, I really haven't deal with that one issue myself, You can also open the console and see if the Bluetooth and WiFi cables are connected to the motherboard. You can DM if you need help with that.
