I am using a DSl connection in my desktop. My desktop has two OSs - Windows 7 and Ubuntu 12.04. After installing Ubuntu 12.04 last month, I was successfully using internet in my desktop by using the command sudo pppoeconf. Today I received a update notification (via update manager) and I clicked to update. After a while I couldn't browse the internet anymore (and the update process didn't complete). I ran sudo pppoeconf, it seemed that the connection was established. To check the connection I also ran plog and I got the following output:

tanim@maqdesktop:~$ plog
May 17 18:02:06 maqdesktop pppd[3481]: Connect: ppp3 <--> eth0
May 17 18:02:06 maqdesktop pppd[3481]: Remote message: Login ok

May 17 18:02:06 maqdesktop pppd[3481]: secondary DNS address 10.15.0.11

Looks like it hasbeen connected, but I can't browse internet with both firefox and google chrome. But I can connect to internet and browse internet with Windows 7 in the same PC (actually I am writing this using Windows 7).

Any solution to this?

Update: the ifconfig is as follows:

Can you run ifconfig? What is the output of ifconfig? open termenal and run sudo ifconfig – Mitch May 17 '12 at 16:14
