HUGELY FRUSTRATING!! Getting a "network connection timed out" error after waiting three hours for the download to complete is unacceptable.  Had this problem running Windows 7 on an HP wireless laptop, IE 8, and Microsoft Security Essentials as my anti-virus.  I had  just updated my iTunes to the latest version so I didn't want to wipe out the whole thing and re-download as some boards suggested (I'd also tried that last year on another computer that did the same thing on an iPod update - didn't work).  I also did not want to totally disable my anti-virus program.
After reading many discussions online about the problem, here's what worked for me on the first try.  You need to add some Apple and Verisign addresses to your Trusted Sites in Internet Explorer:
In Internet Explorer go to Tools, Internet Options, Security tab.  Click on Trusted sites, then click the Sites button. I also unchecked the "disable server verification (https) for all sites in this zone" box (under the box that will show your trusted sites).  Here's what I added.  (The underlining here is not mine - done by this site reading my entries as internet addresses.  They won't underline  when you enter them in trusted sites):

Worked like a charm!!  This list was culled from several posts from several different discussion forums. I then closed out IE, restarted my computer (just in case :-) ),and updated through iTunes without a problem!
