What is going on is that I want to roll back from wireless access to ethernet 
access and everything I try fails.
The actual negotiation with the ISP is made by the router, it gets an address 
through DHCP and in turn my computer gets one from the router.
Wirelless works flawlessly both in my desktop as in my laptop. When I 
configure my desktop to stop using wireless and start using ethernet I don't 
manage to connect. I don't know where to go from here to make it work.

Thanks,
Antonio

PS - This a cable ISP not DSL but as I said it's the router that takes care of 
it.
