@ sirvice )

if you still find nothing you could try removing the game data (not the savegames) and let it install the patch again

IDK this game sorta died out for me. I like Resistance: Fall of Man much more than this game both single player and multiplayer were more fun to me.

works fine now again. dont know what was going on...

I still cant think of any reasonable explanation.

@lafiel
thx 4 the hint, i will try it the next time problems occur ;)

nah same problems again... did delete and reinstall the updates, problem is occurs again....

im sure this is a R2 specific problem nevertheless im gonna change my router anyways. maybe it helps....

I often have problems where I can't get into CoD games (both WaW and MW), it's usually fixed by restarting both the router and the PS3.
