internet not working

**a12ctic** · 06-12-2006

well today my friend said good bye to his windows partion after it got infected with a virus (again). i burned a new copy of ubuntu last night, the installation went perfectly, but his internet isnt working. i really dont know where to start, its pluged in through a enthranet cord, it says that the interface is active but its not finding the gateway or anything.

thanks guys

What kind of setup is it? Does your friend uses a modem? A router? With DHCP? Please give more details...

And what kind of ethernet card does this computer has?
The output of

Code:

lspci | grep -i ethernet

would be usefull too.

its connected through intranet, its intergrated into his motherboard, the connection is coming from a router. its a DELL 4550. he has dhcp as well.

Do you mean it's a "Dell Dimension 4550" ?
http://support.dell.com/support/edoc...4550/specs.htm

Which version of Ubuntu is it? 6.06?

Can you post the output of

Code:

lspci | grep -i ethernet

?

Plus, what is the output of

Code:

ifconfig

This ethernet card (Intel Pro 10/100) should work fine with the "e100" module.

Try

Code:

dmesg | grep eth

to see if your card is being detected.

If you think the card (integrated) is not being detected, you can insert it manualy:

Code:

sudo modprobe e100

and

Code:

dmesg | tail

to see if it works.

the cards being detected, it just isnt working, ifconfig just told me that eth0 isnt getting any packets sent back and forth

OK, then what is the output of

Code:

cat /etc/network/interfaces

and of

Code:

cat /etc/resolv.conf

What is the router IP address? Can you ping it?

**spencerf** · 06-13-2006

have you dhcpcd eth0 or dhclient eth0?

**a12ctic** · 06-13-2006

what? explain spenc...

i cannot ping the router. also, his resolv.conf is empty. the routers ip is 192.169.1.1

**antidrugue** · 06-13-2006

If your router is setup properly, then the content of /etc/resolv.conf should be something like :

Code:

search
nameserver 192.168.1.1

And what about /etc/network/interfaces? Can you post the content of it?

/etc/network/interfaces reads

auto lo
iface lo inet loopbacj

auto eth1
iface eth1 inet dhcp

auto ath0
iface ath0 inet dhcp

auto wlan0
iface wlan0 inet dhco

auto eth0
