I know a bunch of people have been having this problem and I have narrowed down to the possibility of it being my modem that is the problem..But before I go out and buy a new modem I would like to know what else there is to try (that I haven't already tried.
-Putting ps3 in DMZ
-Opening certain ports on the modem
-Disabling media Server
-Using wired connection
-Downloading in-game, on XMB, and in PS-Store
-Plugging in controller (I figured it wouldn't make any difference at all, but I decided I might as well try everything)
-Waiting (it's been a week, "High Traffic" probably isn't to blame)
The only thing I have managed to do was learn the ins and outs of my router and modem, which is a Qwest 2wire P.o.s. and a linksys router
Any other suggestions?
