    both connections, wired or wi-fi, gets instantly disconnected after connection established.
    system message: “disconnected - you are now offline”
    router event log: connecting via wifi but no name and no IP-address; 25sec later disconnecting
    WLAN-Gerät angemeldet (2,4 GHz). Name: -, IP-Adresse: -, MAC-Adresse: 38E:AD:35:6C:27, Geschwindigkeit 300 Mbit/s.
    WLAN-Gerät abgemeldet (2,4 GHz). Name: -, MAC-Adresse: 38E:AD:35:6C:27.

    Re: WiFi connection instantly disconnects

    any other idea to solve the problem?
    is there an easy way to remove all network settings and reinstall the network-manager to have a new untouched installation
    this might be easier as figure out the details for that problem.....
