In this video I'm fixing WiFi and Bluetooth on a PS3 Slim (25xx series).
I'm replacing faulty step-down converter that provides voltage for WiFI/BT chip.
Some WiFi/BT issues can be solved by replacing this particular chip with no need to replace actual WiFi chip itself.
WiFi chip failure is often a cause of error 8002f1f9 and this repair will most likely fix it.
