Q: Solution for code 3194 what's the answer thanks

I'm asuming you are updating using iTunes. If so, first be sure that you are using the current version of iTunes 11.0.2. If this does not fix the issue then there may be an issue with the host file. To repair the host file follow the steps in Article TS4451: http://support.apple.com/kb/TS4451?viewlocale=en_US

This should resolve the issue. Hope this helps.
