Can't download updates with auto-update for Windows 7

Every time I try to download the auto-updates with my wireless Windows 7 laptop, nothing happens. This only started becoming a problem when it came time to download/install Service Pack 1. Where is a place I can download them manually?

Microsoft Windows Update

my laptop can’t connect to that link. Even though it can still connect to other sites, and my home computer can connect there.

You can always download the updates from your home pc and use a hd to move them to your laptop
