Well, I went to the properties of the Local Area connection and, under
TCP/IP I have only one tab, General and there is no evident place where
I can turn on DHCP. I went to the advanced screen and can't find in any
of the tabs (IP settings, DNS, WINS and options) anything that suggest
that can activate DHCP. Where do I do this? and, what does it do? (the
DHCP server is on the router, isn't it?)

Actually what I tried was to test the port and the cable that went to
the wired desktop so I disabled the wireless connection on the laptop
and connected the cable that went to the desktop to the laptop and it
could connect to the network, to the setup utility of the router and to
the internet. That, I think, means that the cable and the port on the
router works.

I am puzzled at the fact that I can ping the router and the DNS server
on my ISP but I am not able to get to it's setup utility on the browser
nor to the internet. If I can ping the DNS servers on my ISP, isn't it
true that I am actually getting to the internet? If that's true, why
can't I browse it? The same is true for pinging the router. If I can
ping it, then why I cannot get it to display its setup page?

You're trying and that's great and I sincerely thank you,
