Would you be willing to answer a few brief questions about PlayStation Forums?
...and I keep getting this error code 8002ad3d, and occasionally 8002a231.
Have you tried resetting your modem and router? Also, what results do you get when you perform the network test on the PS3?
After tests all things are normal. NAT type 2. 100% connection to router.
In the connection status area does it say upnp enabled?
