I think i found cause of my all problems with no internet. DHCP deamon doesen't work. I have to enter, as a root:
at every boot in order to connect to internet. Don't know why dhcp deamons doesen't start automatically at boot. I even created a file and put script from Alien Bob webpage. than chmodded it, but id doesen't work either for me.
I had to put
to a /etc/rc.d/rc.local
I would like to know why without this, dhcp deamon doesn't run automatically at boot. Is there a way to configure it in some way?
