[ethernet] eth0 connection does not run

rafmav · 2009-12-14 08:15:39

My ethernet connection does not run! This is the reply from ifconfig:

$ ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:23:8B:FD:F5:48 
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

So my computer is connected, but all messages are dropped or in error.

Does somebody knows how to solve that problem, please.

I've never seen errors like that, so I'm guessing it's a hardware fault. Did the card work previously? Does it work under other OSes?

tomk · 2009-12-14 10:40:10

Also check dmesg for any relevant errors.

eldragon · 2009-12-14 12:02:37

are you connected to a hub? or a switch? there shouldnt be collisions if its a switch. most likely broken hw or cable

rafmav · 2009-12-14 13:14:33

Thanks for these replies! and fast!

I am not connected with a hub or a switch: it is a MODEM/ROUTER TrendNet TEW435BRM which goes well for DSL.
I cannot run dmesg for know... I will look in it later.

The computer is a new laptop (netbook type): Acer Aspire 1410 722G25n, Intel Celeron Mobile processor 723 (1.2 GHz, 800 MHz FSB, 1 Core, 64 Bits, 1M cache..., 10Watts max...), VGA: Intel GMA 4500MHD UP to 732 MB DVMT, 11.6" HD LED LCD
RAM: 2 GB memory, STORAGE: 250 GB HDD, WLAN: Acer Nplify 802.11b/g/Draft-N,
BATTERY: 6-cell 4400mAh Li-ion, SE: Windows Vista Home Premium OEM (EULA refuse by myself and deleted so not tested with it!).

$ lspci
01:00.0 Ethernet controller: Attansic Technology Corp. Device 1063 [1969:1063]

On the internet, some said that it is known as an Atheros AR8131 PCI-E Gigabit under Windows... and that the useful linux package is AR81Family-v1.0.0.10.tar.gz for them, but impossible to find on the internet (official site is down, the archive found elsewhere do not uncompress, etc...)

Linux is archlinux x86_64. The kernel driver in use is "atl1c" (on my ASUS eeepc beside, it is atl2 and runs well).

Ok, so:
- 1 read dmesg
- 2 try with another cable (the wire I used is old).
- 3 try with another kernel driver (have to find it)
- 4 send back the computer to be repaired!

Bye

Don't forget:
- 5 try under another OS

rafmav · 2009-12-16 16:59:22

My computer runs under ubuntu 9.04 with the same wire that before: 2, 4 and 5 are solved!
Under ubuntu, the driver is atl1c from attansic (the same that under archlinux)
dmesg said:

$ sudo dmesg | grep eth0
[   14.466660] atl1c 0000:01:00.0: atl1c: eth0 NIC Link is Up<100 Mbps Full Duplex>
[   24.848019] eth0: no IPv6 routers present

So I still have to solve 1 and 3... under Archlinux (I left ubuntu one or two years ago).
And I add:
-6: try with archlinux 32 bits alias i686, because I installed the 64 bits x86_64.
More when I have set up arch on another partition of this computer.

Thanks.

most likely this has to do with the kernel drivers, ubuntu 9.04 still used 2.6.28. There were some problems with Atheros Ethernet with 2.6.30, but it seems most got fixed in 31.

I would add:
-0 google "your card linux"
skimming through these bug reports it seems a fix is under way with the soon-to-expect kernel update to 2.6.32. In the meantime, try adding acpi=off to your grub kernel line.

edit: do not bother reinstalling with 32 bit yet, this will most likely make no difference

Kernel 2.6.32 is in [testing] might be worth a try.

actually your computer is not connected (no IP address) so obviously everything is dropped.

this is pretty new card it seems
check if you have atl1 module installed,
if not get drivers:
and install

then
try (if after depmod/reboot it still will not pick up IP)
sudo dhcpcd eth0
see if you are getting any error, and check /var/log/messages.log

Thanks for these replies.

I created 2 partitions more of 16 Go (size of the best quality/price of an USB key for an easy and costless backup) on my HDD 250Go, to install archlinux core 32 bits on one and archlinux 64 bits on the other one this morning. The other ones are: 16Go for ubuntu 9.10 (replace 9.04), 4Go for the swap (I want to make some suspend to disk) and 100Mo for /boot (shared between my linuxes).

- with archlinux 32 bits, the problems with eth0 are the same that with 64 bits.
- Yes, I agree, it could have been a problem with ACPI, because the Wifi connection runs until I plug or unplug the electrical thread to 220 Volts... Each time I have to reconnect it manually (not endly configured yet, because I want to
- Yes, my computer is connected: before doing this, all the values are zeros 0; after plugging the ethernet, the values are those of above;
- Yes, my computer has no IP address, so I cannot use the ethernet.

Ok, I will look for another kernel and control the versions of it under ubuntu and under archlinux and compare.

Might I use the ubuntu kernel with archlinux to see if eth0 runs...

hokasch · 2009-12-17 14:11:16

Did you actually try booting with acpi=off? I took this from the bug reports, where people with the same network card & same problems reported it to be a workaround.
If you want to try another kernel, I would go with 2.6.32, as ROOKIE pointed out you can get it from testing.
