I am installing gentoo on a new Lenovo laptop.

Unfortunately , I choke on the first step - setting up the internet connection

ifconfig gives out no info about eth*, so I think gentoo mini-CD doesn't detect my ethernet card.

lspci gives this:

Code:
    08:00.0 Ethernet controller: Qualcomm Atheros QCA8171 Gigabit Ethernet (rev10)


lspci -nn tells
Code:

     vender ID: 0x1969
     device ID: 0x10a1


uname -r give this:

Code:
  3.8.13-gentoo



I searched the kernel source : include/linux/pci_ids.h

and found

Code:
    #define PCI_VENDOR_ID_ATTANSIC      0x1969


but sadly, not found any

Code:
    #define  PCI_DEVICE_ID_*  0x10a1


but I found that in source drivers/pci/quirks.c, there is :

Code:
 DECLARE_PCI_FIXUP_FINAL(PCI_VENDOR_ID_ATTANSIC, 0x10a1,
                        quirk_msi_intx_disable_qca_bug);


All the infos above mean that there is no driver for this specific card and it seems this card is buggy

So what driver or what workaround should I use to make my install process going on ?

Hi,

This solution is based on a working gentoo, but I still not install it yet ;-(

But thank you all the same, I now get some clues.

Hi,


ifconfig -a :
Code:

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 0  (Local Loopback)
        RX packets 2  bytes 36 (36.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 2  bytes 36 (36.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

wlp9s0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 48:d2:24:4a:57:92  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0



And for the wireless interface wlp9s0, lspci -k tells me that ath9k is in use,
but after I run net-setup wlp9s0, it still retrieved no IP address.

I just realized you are about to install Gentoo. Please use SystemRescueCd, it has much better hardware support.

Hi I also have a Lenovo g500 that uses similar card. For Ethernet alx module you need very recent kernel. I installed from a live Ubuntu through terminal chroot etc. I find it easier and I could connect wireless from Ubuntu. After installation I use wpa suppl, it proved to be more rock solid than wild. You can install wild and use it through curses and upgrade your kernel afterwards
