Connection Lost - Read timed out.

Affects any version. I have Minecraft on 2 laptops and 1 desktop, not mine. No matter where I go, what Internet I have, this happens: Every time I join a server, I play for a while (2-5 minutes), then every entity freezes can't do anything. Weirdly, if I use hamachi to play with friends, this bug doesn't happen. Anyway, I'd like a way to stop this bug.
