Ever since ISPs from AT&T to Time Warner Cable, my PS3 has been having problems. I'm getting very low speeds and my games take a while to load menus now also. I also get disconnected from games and servers randomly. When I do a connection test it says I have the error code 80029020. Some of the solutions I saw were putting the system in DMZ (which I did), disable media servers (which I did), and port forward (which I am having trouble with). Almost every other device is fine (the only other one encountering problems is my Roku player). Any help would be appreciated.
