Thank you for the suggestions. I was able to get the game working for a couple hours a few days ago in the early AM hours. I even had the opportunity to log off on my own after playing a few quests! Unfortunately, ever since then, the problem has persisted twofold. I'm able to play for about a minute before being disconnected with 2002 or 90002 errors, if I'm even able to make the connection work in the first place.

I did try setting up a wired connection, but it does not work. I will call my ISP tomorrow and have them check the port ranges you recommended. I will update the thread once I test things out. Thanks again.
