Tried refreshing? The page obviously isn't loading properly, and since it's only on your laptop I'm guessing you've got a dodgy wireless card/router or a weak signal because you're too far out of range or there's something blocking it.
Might be annoying, but it's just one of those little problems you're likely to encounter as a wifi (or a dodgy or busy cable network) user. Truth be told I actually have 2 wireless cards in my laptop right now because I don't trust the internal intel one.
If you're finding this happens a lot, try connecting your laptop to the router with an ethernet cable and noting the difference.
