It doesn't sound like an selinux issue, but I suppose it could be. 

Does: 

ausearch -m avc

show any denials that look related?

Have you applied all updates? 

(Note that the f12 machine is end of life and no longer gets any
updates at all, you should upgrade it to a supported release). 

Also, /var/log/messages may well have some things from NetworkManager
that could give hints as to where it's going wrong.
