It sounds like you're having similar problems to me. I don't suppose you're on virgin media and use the Super hub as well, do you? I have a feeling that one of those things is the cause.
Any more techy minded folk know why my PS3 downloads files at around a quarter of the speed at which my connection is capable of?
I've altered the DNS settings on one of the other accounts on the console (For US Netflix), do they transfer across all accounts on the machine, and would they affect the speed at which I download from the store? Thanks if any of you know.
My downloads go at such a slow pace on PS3 most of the time when all my other systems go fine (though I had a bit of an issue with my Wii U not too long ago but I managed to fix that). I even had to restart the NFS patch 5 times yesterday before it finally managed to do it without disconnecting. Strangely though, it appears to download fine when PS+ does it's automatic updating and downloading stuff.
Still, I really enjoyed what I played of NFS last night!
