I have run 'make menuconfig' and I have configured everything as it has been told.
In the end, everything seemed perfect, no error message, no kernel panic when I rebooted.
The graphic mode was ok.
However no connection. I have edited /etc/rc.d/net with DHCP. However, when I run #ping 8.8.8.8 the result is that the network is unreachable
either with the intel card or with the RTL8169.
If I run #ip link show there is only lo, no device corresponding to an ethernet controller is recognized but if I run #lspci the intel controller is there:Ethernet controller: Intel Corporation 82574L Gigabit Network Connection.
I shall remark that when I first installed Crux 3.1 I made no changes concerning the kernel (linux-3.12.24) contained on the installation disc
and I had no problem with the network. the ethernet controller was recognized as enp3s6 when I first rebooted and I could connect to the internet.
