I've tried to connect to google but i always fail. so yeah I'm not connected or at least theres a problem.

ifconfig showed this:
Link encap: Lovsl loopback
inet addr: 127.0.0.1 Mask: 255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1

RX bytes: 900 (900.0 b) TX bytes: 900 (900.0 b)

I don't know how to ping a website but I changed the setting in about:config and nothing happened.
