Still, that means that the problem is tied to my main house internet connection somehow, despite the fact that someone else in the house is using that exact same connection and is playing fine.

Are you both connecting the same way. I mean, for example, is the other person directly connected to the router and you're wirelessly connected? Or perhaps your wireless card is not working at its best?

Yup, both connecting the exact same way through wireless connection. Must be something to do with how specifically my computer is communicating with the servers or the router / internet in general. But again, nothing on here has changed since the beta when everything worked fine.
