Thanks for responding. I was hoping a more recent firmware update would help with issues with network when using USB hubs that are well documented in other threads. It does appear that raspberrypi-bootloader is installed, since apt-get tells me its at the latest version. When I try to execute it I get command not found. find and whereis are not telling me where to look, and its not in /usr/bin like rpi-config would have been. My Linux experience has been limited to playing around Ubuntu, I would appreciate any help if I am going about this the wrong way.
