    No internet unless wireshark is active

    This could be crazy , but if i start a dhcp wired connection on my kali , it won recieve a dhcp lease from router unless i start wireshark on that interface !!!!
    I gave up on network-manager and installed wicd , i removed completly network manager from my system , but for some unknow reason i am unable to get a normal dhcp lease from router .

    my interfaces file is simple as it could be :
    # This file describes the network interfaces available on your system
    # and how to activate them. For more information, see interfaces(5).

    # The loopback network interface
    auto lo
    iface lo inet loopback

    # The primary network interface
    # allow-hotplug eth0
    auto eth0
    iface eth0 inet dhcp
    Static ip address is not working on dns level , witch means that i can set an static ip but for some unknow reason i am unable to resolve dns requests .
    and in resolv.conf everything is fine .

    nameserver 1.1.1.1
    nameserver 10.1.1.0
    This is what happens when i restart networking :

    DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 19
    DHCPREQUEST on eth0 to 255.255.255.255 port 67
    DHCPOFFER from 1.1.1.1 (This part is when i start wireshark)
    DHCPACK from 1.1.1.1
    bound to 1.1.1.10 -- renewal in 3594 seconds.
    done.
    if i shutdown wireshark then i loose internet .
    Funny as it seems to be , it is breaking my head of to figure out what is going on .
