Can you ping your router by IP address?  What is the error message if that 
doesn't work?

Can you connect to your router configuration page (if there is one) via IP 
address? What is the error message if that doesn't work?

Although the cable is disconnected there might be still a default route 
entry via your cable interface. Check the output of the "route -n" 
command. There should be only one line starting with "0.0.0.0" which is 
the default route.

Other than that, could there be a firewall somewhere? Please check your 
router configuration, there might be filter rules which prevent your 
machine from accessing the internet.
