Hello,

I`m having problems with my broadband connection. The computer can connect to my router and other computers in my network and all the other computers can access this computer. But I have no internet connection.

If I change
managed=false - > true
in /etc/NetworkManager/nm-system-settings.conf


I can get internet to work but I cannot asign a static IP and the computer is not visible in my home network so no other computer can access it.

any kind of help appreciated !!!
