Its really weird, my connection on my pc is flawless, i can use the browser on my ps3 fine.. but it takes ages to sign in (20 attempts ish) and it will log out after 5 or 10 minutes. i have no idea what is wrong!
when i do connection test in network settings it does IP and internet instantly but fails on connecting to PSN.
up untill yesterday it was fine. IT SUCKS! i wanna play MAG
