I tryed to fix the connection by hooking up my internet strait to my ps3 instead of through wireless but that still doesnt work so I dont think its my connection if I have it connected strait up to the modem. It has to be somthing else. I cant even play anymore cause every time I get in a match I freez up after a few second and them peole kill me and I get booted out for not moving. Its completly uplayable for me now.
It could be the actual connection between you and your ISP (outside of the modem) or a problem with the modem itself.
It's one of those "only as good as the weakest link" kind of things...
