I'm a beginner using Debian. I've just installed Debian 7.5.0 amd netinst. When I execute
apt-get update I get errors like:
Could not resolve 'http.debian.org'
Thus I changed the mirrors several times in
/etc/apt/sources.list but without any result. I deduced that it is because of the absence of internet connection.
So I executed
ifconfig -a, the output indicates only the loopback no eth0 interface. However the Ethernet card and WLAN card are pretty detected, I checked it through
lspci and both cards appear.
/etc/network/interfacesl by adding DHCP but it was in vain.
Please, could anybody help me?
