, hangs after 10 seconds , can't anything.

i have fixed problem. if else has problem here happened. let network-manager update when not use it. wrote on interfaces file , screwed up. had broadcast same ip , netmask @ /32. purged network-manager , redid files, normal. tell apt not install network-manager on upgrade.
