Sound and networking not working after fedup from 20 to 22

[fedora2015]

I know this is very vague, but I don't have access to the machine in 
question for the time being. A friend of mine, who is even less 
experienced than myself, used "fedup --network 22 --product=nonproduct" 
to upgrade from fedora 20 to 22. His sound and networking stopped 
functioning.

When he boots into his machine he gets "network has been disconnected" 
as a message. "Enable networking" is checked in network manageer"

"ONBOOT= Yes" is also there in the appropriate ifcfg confi files.

Regarding the sound...I'm not sure where to start. A push in the right 
direction would be appreciated...
