OS: Debian 8.6->testing As I can't custom the WIFI DNS on Debian, I thought there are something wrong for network-manager & its settings. So, I uninstalled it with sudo apt remove network-manager sudo apt autoremove It's really stupid to do it from current viewpoint as you are offline after then. You can't reinstall them from repository. 😣 Even I plugged the wired, no way. After google, I used the 'dpkg' command to recover the network-manager from Debian archives as following: sudo dpkg -i /var/cache/apt/archives/network-manager*.deb After that, Debian prompts lack of dependency about libndp0 & libteamdct10. So, install them first with dpkg command: sudo dpkg -i /var/cache/apt/archives/libndp*.deb sudo dpkg -i /var/cache/apt/archives/libteamdct*.deb Finally, repeat dpkg for network-manager*.deb, the problem solved. No need to reinstall.😂
