[Solved] Wired internet not working

[Jordi]

Hello,

New to Kubuntu, I tried to configure my wired network.
I gave me the same IP Adress I have with windows, the same Domain name, the same mask, I configured the default route as my router, the same workgroup.

Konqueror does not react to www.google.com
A ping www.google.com does nothing in a terminal
A ping to the router give the message : Host unreachable
A ping to myself gives results.

I configured my network in the screen :
=> KMenu => system configuration => network configuration

An ifconfig does show l0 and eth0 with my configuration but with 0 at transfers.

Because the ping to myself does works, I think my network card isn't the problem..
Does anyone have an idea?

Re: Wired internet not working

don't know...
could you please post the result of:

ifconfig -a

to see all the network interfaces

netstat -rn

to see the routing table

cat /etc/network/interfaces

to see what the network config file looks like.

and

cat /etc/resolv.conf

to see the dns config file

thanks.

Re: Wired internet not working

from what you posted:
a) your interface is not configured and it is down
b) routing's not set
c) please notice that a windoze "workgroup" is meaningless in linux -> remove that.

is this a dsl router at home you need to connect to?

[Jordi]

Re: Wired internet not working

It isn't a router DSL as far as I know.
It is a Conceptronic Firewall Broadband router.
Here is a link to its description :
http://www.conceptronic.net/site/Des...Prod=C100BRS4H

I have configures my network with network manager, what does I have to do configure my interface with the routes and to put it on?

[jankushka]

Re: Wired internet not working

alright.
retry the network configuration with the given configuration gui.
but leave the "domain" field blank.
commit the changes.
you probably also need a "netmask" value, together with the ip address.
check that in your windoze setup.
then try connecting again.

the info you enter must come up with the commands i post earlier once commited.
if they don't, then we can try put them there manually and see what happens.

Re: Wired internet not working

The configuration has been reset without domain.

The problem is that the light on the switch ( and the light on the computer ) doesn't go on by starting Kubuntu and the KNetworkManager icon in the menu bar is on "disconnected"... but the wire is connected!

May it be a hardware problem?
The network wire is directly connected to the mother board, there is no specific network card.

Re: Wired internet not working

i don't know the device you're using.
i've no experience with it.
but if your box connects with windoze, then hw is ok.

let's try manual configuration.

hit alt-f2 and enter (i assume you're still on kde3.5.x):

kdesudo kate /etc/network/interfaces

if kate doesn't work, see what editors you've got in kmenu...

make sure your file look like so:

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0

auto eth0
iface eth0 inet static
address nnn.nnn.nnn.nnn
netmask nnn.nnn.nnn.nnn
gateway nnn.nnn.nnn.nnn

of course, put the actual ip addresses in place of nnn.nnn.nnn.nnn.
save and exit.

then hit alt-f2 again and edit /etc/resolv.conf.
make sure it look like so:

nameserver 195.235.113.3
nameserver 194.179.1.100

save and exit.

finally reboot and see what happens.

Re: Wired internet not working

It works thanks a lot!!!

I've done two things :
First, I have done the modifications you said.
Every thing gone fine, but at the reboot....no internet.

Then, I tried it with a network card inside my computer ( instead of my chipset ) and it works.

So to all the people who have a mother board Gigabyte S-series GA-G31M-S2L => buy a network card!
( The mine is an Ovislink con Chipset Realtek, number EVO-8139ITX )

Re: [Solved] Wired internet not working

if you simply type:

/etc/resolv.conf

your command interpreter will try to execute the file.
that's not what you want to do.
if you want to make sure the file be there, you simply navigate to it with your file manager.
that is, with konqueror or dolphin.
then you just click on it to see what's inside.

from the command line you'd type:

cat /etc/resolv.conf

if you want to edit the file, you'd type:

sudo kate /etc/resolv.conf

sudo is needed 'cause you need admin privileges to edit this system's file.


cheers.
