Sometimes? I'm using a router, but I haven't fiddled with this port and PS connects just fine :] Someone else will have to come and explain that one.

czaja1026: are you running any antivirus software that may interefere? Or on the other hand, have you run any antivirus checks recently to make sure your system is alright? (Not that this may be the issue.)

Can you you describe more about your net freezing? What exactly happens? You lose connection to PS, or you lose connection to your entire modem/cable/ISP?

disconnect looks like this:
i can walk and attack but not trade chat etc..
and after 5 mins of "invisible" disconnect it says serv is not responding
looking on connection icon : says internet connection active
when launching IE .. it says cant find the server check your internet connection o_o'
and i got avast! antivirus ..
and i dunno .. bcuz .. check this :
