Go to "My Network Places' it should be on desktop, or in your start menu.
It will probably be blank, so click on the link on the left that says "View Network Connections"
You should see a LAN Connection. See if it says connected or not.
If it is connected go to your browser and type in:
213.208.106.212
This should bring up a page of your modem settings. Have a look around til you can find the one that states what protocol you should be using, it should as Shippou said be PPPoA not PPPoE as it currently is.
You may have to run the whole set-up process again, just be sure to pick PPPoA this time around. You may have accidentally just clicked continue at some point when you should have changed the option.
Let us know if any of this works.
