Ok that seems good (at least for me)

that seems to be ok also

can you do a traceroute for this ip?
gengi at eragon:~$ traceroute 66.249.85.99

> The cmd doesn't work
the instructions has to be done on the windows box (dont know if you need 
to be admin)

> I don't know how contact the router
routers address should be 192.168.1.1

can you try to do 
gengi at eragon:~$ nslookup www.google.com

By the way do you have a working internet connection on your windows box?
And how exactly do you connect to internet

$$MS$$----------
192.168.1.XXX   \
                 ---192.168.1.1--- internet
                /  (DSL router)
Ubunut----------
192.168.1.15

is the above picture right?

you can try install etherape (sudo apt-get install etherape )and while
etherape is running do a ping (its a sort of graphical traceroute)
