Ok Im running windows xp professional right now, i boot Live Cd Ubuntu 9.04 on my laptop Plug the LAN ethernet cord from my router to my laptop ethernet port on laptop, when it boots in it automaticly connects on my laptop and my modem glows up on that port(Meaning it found a computer)..

On my PC (Running now) i do same thing but in this case the router does not glow in live cd, only in windows xp And my ethernet cord is pluged in same place everything but sounds like my ethernet port is not sending power when running live cd.

P.S my Laptop has xp aswell.

It is not that the PC sends power. It is the link connection status shown by the router.
The reason the modem port is not glowing may be because of lots of reasons
1. The network card is not recognized
2. The network interface is not up
3. The cable is faulty
4. ...

The best bet to start is to
open a terminal and send us the output of
$ ifconfig -a

Output For: IfConfig -a

looks like there is no IP address assigned.

can you do a manual up of the interface

as root:

# ifconfig eth0 up

this must bring the connection LED to glow on the router. If not then there is some cable issue I think.

next try to get the IP

# dhclient eth0

this must get you the IP if the step 1 looks successful.

I did not have permission?? So it wouldnt work, BTW im on ubuntu 9.04

sorry i was not clear enough.
The commands need root access
you must he typing


$ sudo ifconfig eth0 up
and
$ sudo dhclient eth0

this will ask for password and give your account password you use to login to the machine.

So i type $ sudo ifconfig eth0 up esacly? then the LED light should show up? Im running live cd they;re for i got no password?

Says Bash: $ : command not found.

can you post the results of an lspci.

also dmesg | grep ether mite be useful

sudo lspci

Please Anyone???

not sure. what is the result of ifconfig and ifconfig -a

not sure if i am reading this correctly but when you connect a different physical ethernet card to an internet receiver (read dsl/ cable modem) you have to unplug both devices so that the hwaddress stored on the internet receiver can be reset.

Solved went to device manager windows xp and my network card then wake on lan when shutdown

^ huh. i'm not sure how the resolution solved the problem but glad to hear you got your internet working.
