broadband

Hi everyone,

I am currently having a hard time on getting the mobile broadband connection running on ubuntu 10.04(lucid lynx).

I am using a USB modem and used wvdial to connect to the web It went like:

Sending ATZ ...
OK
sending some more flags
OK
modem initialized
connecting
Local IP x.x.x.x
Remote IP y.y.y.y
Primary DNS z.z.z.z
Secondary DNS a.a.a.a
(Some more output)

I tested this with invalid username to make sure it is really connected and i think it was connected as connection failed with invalid usernames.

Now when I do a remote ping say 8.8.8.8 (Google DNS servers), the ping says unreachable

I think this might be because the system may be using the ethernet to send packets which was indeed disconnected.

So can anyone help me out with this. How can I select ppp as the interface to send packets or is there some other problem.

A command line solution will be appreciated as my network manager applet doesnt works correctly.

Any help is much much appreciated.

-- thx
