Ever since I got a new DSL modem from my ISP (the old one broke) I haven't been able to hold a connection while on FFXI. I play on PS2, btw. I'll log on okay and the connection will seem great for a few minutes, but then suddenly the S and R numbers in the upper right corner of the screen will start dropping real low, into the double digits. Then I'm kicked off with a "FFXI-4002" error, followed by a "POL-0512" error once I've confirmed that. This happens every single time.
I tried getting support by going to SE's support center site and filling out their e-mail support form. But all I got back was an e-mail saying that they could not help me with this issue over e-mail (no idea why) and that I have two options. Either try contacting them again through their toll free chat room on their support site which doesn't seem to exist. Or call them on some non-800 number that is not toll free.
I also tried posting in the tech support section of the official forums, but was pretty much ignored there. So helpful.
