Hello, your cat 5E Ethernet cable is about 20 meters long and connects from your router to another room. When plugged into your PC, it delivers the expected speed, but when connected to the PlayStation, the internet connection feels slower. Using a short Ethernet cable between the PlayStation and the router improves performance. It looks like the cable length affects the speed—your PC seems to receive it well while the PlayStation does not. If you want to fix this or know if there’s a better setup, let me know. Best regards.
