Hi I have just finished a fresh install of gentoo and when I boot up I have no network card showing up for eth0.

I have ran ifconfig and it shows a loopback and a wireless card but not ethernet.

The eth0 loaded ok when booting to live cd.

please can I get a hand.

RoboGrinch ... welcome to gentoo.

The most obvious reason is that you omited to enable the driver in the kernel. Assuming you can't connect via wireless then boot the cd, chroot, 'emerge sys-apps/pciutils', and run the following:

Code:
# lspci -v | awk -v RS= '/Ether/{print $0 "\n"}'

... this should provide info on the ethernet controller. You can then search for the card, and the respective driver, and check to see its enabled in the kernel ... or provide that info here.

best ... khay

RoboGrinch ... that would be the alx driver. So, you'll find it under 'drivers => net => ethernet => atheros' in menuconfig.

If you used genkernel (and I assume you did) you would run 'genkernel --menuconfig all' ... and navigate to CONFIG_ALX and enable it (either as a module or builtin).

best & you're welcome ... khay

RoboGrinch,

You need the ALX module.

If you are a genkernel user, when genkernel drops you into menuconfig, press / and enter ALX

Among other things, it will tell you
Code:
  │ Symbol: ALX [=n]
  │ Type  : tristate 
  │ Prompt: Qualcomm Atheros AR816x/AR817x support     
  │   Location: 
  │     -> Device Drivers   
  │       -> Network device support (NETDEVICES [=y])   
  │         -> Ethernet driver support (ETHERNET [=y])   
  │ (1)       -> Atheros devices (NET_VENDOR_ATHEROS [=y])   
  │   Defined at drivers/net/ethernet/atheros/Kconfig:64   
  │   Depends on: NETDEVICES [=y] && ETHERNET [=y] && NET_VENDOR_ATHEROS [=y] && PCI [=y] 
  │   Selects: CRC32 [=y] && MDIO [=n]


Follow the location and set it to <*> or to <M>.
Unless all the Depends on: are selected the option will be hidden.

Let genkernel do its thing. If you are not a genkernel user, rebuild and reinstall your kernel.
