Arch Upgrade "Lost" My NIC Card

FredJones · 03-21-2012, 01:40 PM

New install of 64 bit Arch. I turned on the network via dhcpcd eth0 and I was online fine and got my packages etc. I upgraded everything to latest (including removing my locale.sh file I think) and installed Xorg and Xfce. Then I added to /etc/rc.conf:

Code:

# DHCP example
# interface=eth0
# address=
# netmask=
# gateway=

interface=eth0
address=
netmask=
broadcast=
gateway=

Which is what my other Arch box on this same LAN has. Now when I reboot I get:

Code:

[root@myhost ~]# dhcpcd eth0
dhcpcd[572]: version 5.5.4 starting
dhcpcd[572]: Kernel is not configured to accept IPv6 RAs
dhcpcd[572]: eth0: interface not found or invalid

I removed

Code:

interface=eth0

and rebooted, but it's the same. lspci says I have a Realtek Semiconductor Co. RTL8101E/RTL8102E PCI Express Fast Ethernet Controller

I tried modprobe rtl8187se and modprobe 8139too and modprobe r8169 and then dhcpcd eth0 again but no go.

I rebooted and get this:

Code:

[root@myhost ~]# dhcpcd
dhcpcd[572]: version 5.5.4 starting
dhcpcd[572]: Kernel is not configured to accept IPv6 RAs
dhcpcd[572]: no valid interfaces found
dhcpcd[572]: no interfaces have a carrier
dhcpcd[572]: forked to background, child pid 573

dmesg|grep eth shows no results.

But after the initial install dhcpcd eth0 worked and got me online. Something in all the upgrades (and reboot) broke it.

There's this:

Code:

$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

and on my working PC:

Code:

$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 70:71:bc:9a:f0:82 brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.1/24 brd 10.0.0.255 scope global eth0
    inet6 fe80::7271:bcff:fe9a:f082/64 scope link 
       valid_lft forever preferred_lft forever

I'm lost now.

This would probably get more results in the Arch section...

Could you post your rc.conf?

what are the results from

Code:

lspci -nnvv

?

Thanks for your reply. The forums at Arch couldn't figure it out either. I just dumped it and installed Debian--works perfect, out of the box.

Thanks
