    I am facing the exact same problem.

    I had already been looking in the forum for a solution but nothing worked until now.
    To solve it I tried the following:
    1. edit "/etc/resolv.conf" and changed nameserver from "" to "".
    2. edit "/etc/NetworkManager/NetworkManager.conf" and changed "managed=false" to "managed=true".

    My current workaround is to run "service network-manager restart" but as I have to do it every few minutes it's kind of a mess.

    I'm also having this issue however mines not even generating the nameserver did you figure out a better fix for it?

    To all,

    Have you ruled out any hardware problems (i.e. router, ISP, etc)? Anything nearby causing signal interference?

    While this happens I am still connected to my router and can access its web interface. Only my Kali stick is facing this problem, other devices run fine. So the router (DNS) configuration should be fine.

    Right now I am using this script as dirty workaround. It will restart the network-manager if I am loosing connection:


    while true;
    echo "Check if connected..."
    x=`ping -c1 2>&1 | grep unknown`
    if [ ! "$x" = "" ]; then
    echo "It's down! Try to restart."
    service network-manager restart
    sleep 5s

    Maybe you need to adjust the "unknown" to your system language settings.
