Bumping this, I also have this same problem described in the opening post. Random R0s with all ports unlocked happening every hour or two along with my connection crapping out at the same time it happens.

The connection works fine throughout the day without FFXI running and other mmos I play work perfectly. It is a FFXI issue. POL-0006 and POL 2059 are the main ones I get with sometimes others.

I have scanned my computer for anything else that could cause this, spyware or adware and nothing has been found.

If the op found a solution, I'd also like to hear it.
