View Full Version : [ubuntu] can't connect via ethernet- help :D

Hi all

Recently obtained an ethernet cable so that i can hookup to the router direct rather than using the wireless. Well I get lights at both ends
but am unable to connect to the net. I am using Wicd as my network manager.
here are the results of some terminal entries.

description: Ethernet interface
product: LNE100TX
vendor: Lite-On Communications Inc
physical id: 9
bus info: pci@0000:05:09.0
logical name: eth0
version: 20
serial: 00:c0:f0:57:1c:6d
width: 32 bits
clock: 33MHz
capabilities: bus_master ethernet physical
configuration: broadcast=yes driver=tulip driverversion=1.1.15 latency=64 module=tulip multicast=yes

eth0 Link encap:Ethernet HWaddr 00:c0:f0:57:1c:6d
inet6 addr: fe80::2c0:f0ff:fe57:1c6d/64 Scope:Link
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:629 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:93327 (91.1 KB)
Interrupt:21 Base address:0xe800

Can I establish if my NIC just isn't linux friendly or are there further
terminal enquiries I can do to see whats wrong? The Router modem is a belkin54g which I can connect with the cable to my eeepc successfully.

I'm not really familiar with wicd... if it uses /etc/network/interfaces, or keeps information elsewhere. Post /etc/network/interfaces. I'd ask about lshw -C network, but it looks like you've already provided that information.

Hi there

Yes the info is from the lshw input. This is my etc/network/interfaces
which does seem a little empty. Any thoughts?

auto lo
iface lo inet loopback

I will have a look round and see if I can find the code I could put in. I have a vague Idea what it looks like :D

Thanks for looking

Hi again

Found the string to add which was;

auto eth0

iface eth0 inet dhcp

A restart of the network brought up this old chestnut;

fenris@Odhinn:~$ sudo /etc/init.d/networking restart
