X-CTU not getting version updates from web

Hi,
I have some XBees that I’m developing wireless apps for. I am not having much luck getting firmware updates for the modules.
I have 5.1.4.1 loaded, and in the Modem configuration TAB I try
the “DOWNLOAD NEW VERSIONS” Button and then in the next Form, I click on the “Update from Web” button.
All I get is a message box saying, “The Computer is Disconnected from the Network”

I’ve turned off Windows firewall and re-tried but still get the same result.

My other PC updates fine on the same wireless network.

Has anyone had this same problem?

Thanks in advance,

Brian

can you ping 8.8.8.8??
