i upgrade my streamyx to 1mb last month and they gave me this free zyxel wifi modem router. I use wired connection for my ps3. i have no problem signing in psn, send/receive msgs, psn store etc., NAT type 2 in my ps network settings BUT when it comes to playing game, i have a problem with the connection.

MW3 - nat type is moderate
ghost recon future soldier - uplay service error/cannot multiplayer online

anyone here can help me to solve this? i thought of buying new modem router. anyone can suggest me the best model in the market right now.
