Nostalrius Begins - Quality wow vanilla realm (1.12)

I keep getting dc'ed. Anyone else sharing the same fate? Apparantely no one in my guild or bg is. Is it just me? Also, how do I change my password on my account? I don't think I'm getting hacked, but just want to be sure.

EDIT: Probably my client side. Noticed twitch would go down every now and then. But any word on password change? Is there a way to do that?

Thanks.
