Random Disconnecting

[Zerayla]

Details:
Ever since the maintenance from March 7th, I have been experiencing random disconnections (approximately 8-10 times). The incidents are very random, occuring in Abyssea (La Theine) and Windurst Walls so far.

Steps:
Everything but my character would "freeze".
"Network" would begin to slowly go down to 0%.
Black screen loaded with a text box in the center stating that the connection had been lost. (I don't recall the exact wording).
Attempted to log back in immediately after the game crash by restarting the game.
The described incident above would then happen again anywhere from 5 minutes, to sometimes 1 hour later.
After restarting both cable modem and router, made another attempt to log back in to the game but the result was the same.
I have also clicked on the "Check Files" option for FFXI, and "Repaired All Files".

Date & Time: March 7th - March 9th, 2011
Frequency: Often (8-10 times). I have not been able to play for more than 2hrs without experiencing this problem.
Platform: PC
PC Manufacturer & Model Number: Homebuilt Computer
OS: Windows XP Home Edition
Graphics Card: NVIDIA GeForce 8400GS
ISP: Sonic.net
Type of Internet Connection: DSL

Any suggestions would be greatly appreciated.
