Let's try to connect to the router. Please edit /etc/network/interfaces.
You need to be root to edit this file so hit ALT-F2 and enter:
gksudo gedit /etc/network/interfaces
at the bottom add an empty line and then:
auto eth0
iface eth0 inet dhcp
Save that file.
Log out and log in into your gnome desktop again.
Open a terminal window and enter:
$ sudo ifdown eth0
$ sudo ifup eth0
Can you point your webbrowser to http://192.168.1.1 now and see your
routers web interface?
Maybe you need to enter
$ dhclient
Can you reach 192.168.1.1? Can you access internet?
