I don't know for certain if the service pack is to blame for my problem, but it seems like an unusual coincidence that the problems began immediately after my husband installed the service pack on his machine.
Any advice would be appreciated, or it would at least be nice to know if anyone else is experiencing similar problems and whether or not they have installed the service pack too.
Ever since my husband installed it on his machine, the both of us have been disconnecting (R-->0) every 2-5 minutes in the game. We are having no problems with our internet connection and I don't see any other complaints from other players so it doesn't appear to be a widespread problem with the FFXI servers.
He said when he started up Playonline and a dialog box came up he chose the "Unblock" option.
We use a Linksys Router with recent firmware and we have cable internet. We have had our two computers with FFXI (and XP) hooked up to the router since October and never had any problems. We had the right ports open and I think we had to put the my husband's machine in the DMZ to get it to work for both of us. After he installed the service pack he had to disable the firewall and re-open the ports.
The problem affected both me and my husband although I did not install the service pack. It is currently not compatible with my video card so I did not install it. But even when we hooked up my computer directly to our modem I still had connection problems.
We also tried various other configurations such as trying to connect with my machine and the router with my husband's machine turned off. We tried with each of our computer's in the DMZ.
So I don't know what to conclude, because my machine still disconnected even when it bypassed the router and did not have the service pack installed.
Any ideas?
