Lag and d/c

Hello, i have been playing FFXIV for some months and before 3.0 patch i have been playing without any problems, but since expansion come out, i have a lot of lag and continious disconnection problems, that is making game unplayable. I have confirmed that is not an ISP problem, i have checked my internet connection just after a d/c and it was working fine. I have been having problems whatever dx9 or dx11...

Please help me, i want to keep playing this awesome game for so long time, but it's unplayable

Thanks
