I just bought Network Cable RJ45 CAT5 -10 m
is that OK with CAT5, instead of cat-5/6 ?
I didn't see they have cat-5/6, neither cat-6. Should I return it and look for cat-5/6 somewhere else ?

That is fine. cat-5/6 was meant as cat-5 or cat-6 cable.

Robert and Jay,
Now I have disabled wireless and connect my Debian with LAN 1 on the back of my router using the Network Cable RJ45 CAT5.
Can you help me configure the wired connection or point me to a good tutorial on how to do that.
Thank You in advance !

The config in the first post looked to be OK. Check to see if the interface has been enabled with;

Code:

ifconfig

If it hasn't then simply enable it with;

Code:

ifup eth0

Robert,

Here is the output of ifconfig

lucky@cornucopia:~$ sudo ifconfig

It looks like there's something wrong in the 1. paragraph. How do you interpret it ?

Does this mean that the interface hasn't been enabled ?
Should I just enable the wired connection with
ifup eth0
?

That's your network card, and you seem to have a valid IP address from your router.
If you would like, you can test for a connection to the Internet, you can do the following command:

Code:

ping -c 4 www.google.com

That will send 4 ping requests to Google. The results, if good, should look similar to this:

Code:

$ ping -c 4 www.google.com
PING www.l.google.com (173.194.68.103) 56(84) bytes of data.

Jay,

...you seem to have a valid IP address from your router.

I was me who assigned this static IP to it.

The output of

Code:

ping -c 4 www.google.com

is

Code:

ping: unknown host www.google.com

And I can not open any website. It looks like I have no connection.

You need to ensure that your /etc/resolv.conf contains your DNS server:

Code:

search your domain
nameserver dns server 1
nameserver dns server 2

Also lets ensure you have a route configured. What is the output from the following:

Code:

route -n
