This might seem like a stupid question but...
I play online on my ps3,which is hardwired to my router/modem. I live in a building that offers communal internet. I also have my own internet connection (DSL), my own modem, password etc for my network. My question is if I'm gaming on my ps3 using my connection and surfing the net using the connection from my building can this introduce latency in my gaming experience,considering I am using two different connections? I assume they would be separate and not affect each other, but just wanted to ask you guys to make sure.
