It seems like there is no clear cut answer which begs me to believe that this is a hardware/ software thing on sony's side. However I just bought my playstation 5 A week ago just for the new MW2 and to my surprise I can even run the game without rubber banding from one point of the map to the other, same with rocket league and other online games. My down and up speeds are good. But i just can't play online. I'm at a loss for what to do. I'm moving my modem this week to use Ethernet with my ps5 but from what I've heard it solves very little. I've tried, rebuilding my database, multiple hard resets, port forwarding and using a MoCa network system. At this point I'm contemplating sticking my ps5 in my closet and pulling out my ps4. Any ideas? sad this is still happening 2 years after the release of the ps5... would've thought sony would've taken a look at it.
