I'll see if my roommates want to pitch in for better internet, but I still don't understand why similar downloads take longer with the MBP than the Toshiba. Are there security measures on the MBP that could be causing interference? I've read bits here and there about firewalls and ports all other sorts of techno-nonsense that I don't understand, but most of it seemed to be specific to wireless routers, not ethernet connections.
I feel like a caveman around these sort of thing.
