My PS3 has been connected via Ethernet for ages and until now has worked flawlessly. I fire it up today and it says unable to obtain an IP Address. So I then enter my IP Address settings manually. I can now obtain an IP Address, but the test fails on Internet Connection. The weird thing is I can connect fine using a wireless connection. I have rebooted my router and PS3, numerous times but when I choose wired it still comes up with errors.
