It's hard to help with such little information. How is your machine connected to the modem? If via Ethernet, what kind of network card? If via USB, what kind of modem is it?

sorry for the little info,
mine is a standalone desktop machine connected thru a DSL modem.
i have a VIA Rhine II Fast ethernet adapter.
i had the option of connecting the modem thru the USB port but chose to connect it to the LAN port so that i can add any other computer later(say a laptop) which can wirelessly connect to the modem.

Yeah, Ethernet is also easier to get working. Can you post the output of "lsmod" and "ifconfig -a" please?

OK, so the kernel module for your network card is loaded as expected. You sort of have two entries for eth0 in your ifconfig output . Anyway, the IP address that it has isn't a "proper" one. Try "sudo dhclient eth0" and then see what ifconfig says.

Are you sure you're using DHCP under Windows? Also what kind of modem is it?

Hi man, i was having the exact same problem like you, exept that i'm using ADSL (connected to an ADSL modem via ethernet RJ45 cable).

Did a lspci -v command and my ethernet card shows up fine.

When I boot to windows it work. The led light that tells where the the ethernet cable is plug or not blinks; but when i boot to ubuntu (feisty), the the ethernet led on the modem stops blinking.

And when i did a sudo /etc/init.d/networking restart I get the same message like you.

Funny thing, i even change my ip to static and ping my modem which is 192.168.1.1 and no reply.

After many reboots I went to the bios and enable "boot from LAN ROM" in my bios. It shows some funny message. So i reboot again and disable the "boot from Lan rom" option. and voila my ADSL and internet work. I really don't know what was the problem and what i did that made it worked.

I was frustrated enough to almost get a new network card.

I have a Quidway WA1003A series modem which has a built in wireless ADSL router for supporting a local wireless LAN. The manufacturer name is HUAWEI.
