Most likely you have a problem with the nic network interface card in the system. Open the ps3 main menu and select settings network settings. Choose internet connection settings advance settings from the list of network settings select custom then choose proxy server from the list.
I will be fixing mine in the coming days i will inform you if it will work. Unplug all network devices including the ps3 system. Youll get an update error loop and there is no way to fix it but replacing your ps3 motherboard. It is needed for wi fi connectivity and bluetooth. On the proxy server screen select do not use to disable it. Wait a few minutes before turning them back on this will refresh.
Check your router manual to connect. Test your network test your home network by connecting to the internet on another device. Deleted 1 point 3 years ago. Assuming your wirelessbluetooth card is bad or unplugged. I have similaf issue with my ps3 after doing many research it seems that the wifi bluetooth chip need to be replaced or you need to do reballing for the existing chip due to the heat some time it loose connection. Your bluetoothwifi board is probably not working so dont update your ps3 system.
