Hi, I have a motorola cable modem (SBV5120) which is connected via ethernet.

My internet works just fine on Windows 7.

I tried to make it work on Ubuntu and I manually inserted the IP address, Netmask and Gateway.

On Ubuntu it says that I am connected (the littile icon on the top-right corner) but my internet doesn't work.

I read lots of topics about modems (and getting them to work with Ubuntu), but I haven't found anything helpful.

Is there a change that I can solve this problem ?
I really need help. Please post if you know anything that you think is helpful.

PS : Ubuntu is installed under Windows 7.

Did your internet provider give you a static address or tell you to use dhcp? ... also, when you say it worked fine on Windows 7, do you have 2 machines or did you reinstall ? If you have 2 machines you may need to switch the cable modem off then on so that it recognises mac address of the linux host.

cheers

I am also facing the same problem. Here I don't have two machines, I have single machine with dual boot. When I boot into Ubuntu, PC/Activity LED will be off where as when I boot into Windows, It is on and everything will work.

My ISP has not provided any static IP. I am using DHCP for getting IP.

It was working in with ubuntu 7.*.

Please help us to solve this problem.
