Hey mates, I could use some help. I recently upgraded to Comcast Xfinity X1 cable and internet. I configured my PS4 as well as my Xbox360 (I picked up a used one) for internet play. I have all the correct ports open and the firewall configured correctly for peer to peer play, however, when I play online I experience a good amount of lag. This lag only occurs when playing the PS4. My xbox is connected wirelessly and the PS4 can either be wireless or hardwired in. I have tried both wired and wireless and still lag. I would like to try and get this sorted out before FIFA 15, any ideas would be greatly appreciated .
