Comment:

 Well, let's start with information about your network.  How are you
 getting your network access: DSL, Cablemodem, dialup, something else?
 From what provider, in what area of the country?  Have you tried taking
 your XO to another environment (friend's house, coffeeshop) and does this
 allow olpc-update to work?  If you're using wired ethernet, what type of
 adapter are you using.  If you're using wireless, what model of access
 point are you using, and how is it configured (open access, WEP, WPA, WPA2
 encryption, 802.11a, b, or g)?

 All indications are that your local network is broken.  Information about
 how it is broken and whether this brokenness are widespread enough to
 justify workarounds on our side are necessary to make any progress on this
 bug.  (Note that forcing mtu to 1492 will break other networks which
 properly set the MTU, so we can't do this for all users.)

 See http://www.dslreports.com/faq/7801 and
 http://www.dslreports.com/faq/695 for more information about MTU.  You
 should be able to set the MTU on your wireless access point (for example)
 which will fix all applications on your network, not just olpc-update.
