Timo,

you do not need to install "network wired" but that made it some easier.
We are going to set things manually; i am guiding you through menus, but beware: i am calling you the menu-structure of an old version i am using; so perhaps the items i mention here have a different name on your PC...

FIRST:
* wire your PC to the modem/network
* boot your (modem and) PC

SECOND:
* check if connection-LED (if available) on PC and modem is lighting up; is there a "fysical" connection ?!?

THIRD:
I see in your ifconfig-output that the wired card is detected.

Go to <Applications>,... <System>,... <Network>,...
press the button <Unlock> (asks for your password)

select the Wired-Connection (is it checkboex"Active") and select the button <Properties>
The settings here you must read from info from your provider...

After everything is set to the proper settings, select <OK>
Close all program windows and reboot PC.

NOTE:
Some modems require that -after setting network- that the modem is RESET with the connected PC powered ON....

Is this helping you enough?!?
Otherwise please reply as much info as possible; these volunteers will try to help you.

Hi

thanks about the answer. Unfortunatelly it didn't help. If you look the view of ifconfig, it shows that the interface is up and running but one reason or an other, TCP/IP stack is not activated foir this interface.

r timo

Timo,

indeed the interface is detected, but as you can see no RX-packets / TX-packets have been sent out; so that suggests either
- the interface is set inactive
- the interface is not configured completely yet

Both things must be seen in the Network-menu i described previously; there you can see 2 connections, the wireless-one and the wired-one.

Please be so kind and reply here all the settings and check-marks you find in the network menu for the Wired-connection.

Using that information i will try to help you activate this connection...
You did not answer my question about the fysical connection, so i assume that connection is correctly working (often can be seen by green LED lighting up...)

Hi

both connections are enabled and leds blinking quite normally

r timo

Have you tried it command-line,
opena a terminal window and there enter the ONE commandline (broken in 2 lines here, but it is ONE line)

   sudo ifconfig eth0 add 192.168.1.2 netmask 255.255.255.0 up

This adds the IPv4 address 192.168.1.2 to the eth0 network card...

What is the reaction of Ubuntu to this?!?

Hi

and the answer

SIOCSIFNETMASK: Cannot assign requested address

r timo

Hi

problem had nothing to do with linux. Faulty ADSL-modem/DHCP-server caused the problem. I don't understand the mechanism of the problem but now everything is working.

Thank you for your help.
