Recently I updated my fedora box and after that my network manager broken for wireless connection (I was not able to test it for wired), I asked on IRC and nirik told me it is a bug and soon it will fix but if I want to work now then I have to downgrade it but as my network is not working so I was not able to downgrade it, so I just run command for downgrade yum downgrade NetworkManager\* and I found out which packages yum wants to downgrade. (Moe__ told me if my wireless connection name contain any space then it crash nm, he told me to remove all connection and then restart nm. He was right after removed all connection my nm again started but it again crashed as soon I made a wifi connection)
Now I made list of downgraded packages with correct version and then from another machine I downloaded those packages rpm and placed it "/var/cache/yum/i386/15/fedora/packages/" (It's yum cache path where it put package after download) and I again run above command for downgrade. Now NetworkManager successfully downgraded and also resolved my wifi problem.
