I love kali... But when I installed kali 2 , I face a Big big problem..
That is DSL connection problem...
normally it has no dsl connection option..
But using terminal command [ nm-connection-editor ] I have found DSL connection option, I have also made a connection

But using this connection kali is not connecting to the network...

I am also not able to use kali 1.1 because old source not working

Please fix it very quick

You are directly connecting your Kali box to the internet?

Has anyone been able to figure this out? I am having this issue with two of my network cards

it connects fine for about 5 minutes then I loose connection...

how to troubleshoot?
