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.

I apologize for my newbie questions concerning the great Crux which documentation I am still studying a lot.

You're just missing the module or built-in driver.

Easiest way to check is boot the livecd and do lspci -K. This will
list detected hardware on the PCI bus and if applicable the drivers.
Note the RTL8169 name, probably 'r8169'.

When you run 'make menuconfig' to setup your kernel search for the
string using the '/' key and just select it as built-in [y] or module
[m]. Recompile the kernel and you should be good to go.
