Cannot connect to tne Mirrors to update modules

The system is a FreePBX distro version 2.210.62-6 I know I need to upgrade everything, it is at Asterisk version 1.8 as well. On advice of Digium for some issues we are having with PRI calls we need to get this upgraded. Anyway, I can ping out anywhere I want. When I try to Process to update modules I get a Wget error that the mirrors cannot be found. I tried a Yum update and got dependancies errors at the end. Do I need to do the updates manually??

Thanks In advance for any help

Thanks James. Can these updates be run on the system during operations? Will they fix the mirror issues? I also need to upgrade Asterisk on this system.
