I am connecting to the internet through a pppoe connection, but for some reason I can not connect to my modem (it's address is 192.168.1.1).
Before I set my pppoe connection, I could connect.
So, is there a way?
EDIT
The output of ifconfig is :

Setting up your device as a plain modem removes its ability to provide network addresses to your network, instead it acts only as a modem, passing the internet connection directly to your PC.
Looking at your ifconfig:
you can see your internet (external) IP address, and here
you can see you don't have an internal IP address. Hence you will not be able to connect to any other devices in your network.
In your modem/router settings you should have the option to set it up as a router so it gives out IP addresses and shares the internet connection between devices. This setup depends on your router, though.
To reset to factory settings you normally power up the device while holding in the reset button for 30 seconds or so.
