As a few of you guys know I have been having the same problem as others here , not being able to join lobbies. The game freezing just as Im all excited that I actualy got in a lobby etc.
My nat has been moderate for a while.
I had really believed it was the wireless router after looking at some very long threads on here. I had kept meaning to follow some instructions on it but it sort of looked a bit
Then the other night my tv was playing up so I played on my boys pls3 ... And weird It didn't freeze , I joined lobbies , I actually killed more than5 people. The nat was open !
So , it couldn't be the wireless network or router
Anyway so looking on google for ps3 problems someone had put the same problems as me and how to get open nat.
*** Go to the network settings on the menu and simply close the media setting. Then I just reset the wireless network setting. ***
And guess what .. I have open nat , joined lobbies fine , killed more people etc. Yes still some lag but normal blops blips.
Ps .. Sorry if this way ad already been noted , just could read through it all x
