The webconfigurator page of the router which I use to connect my
computers to the ISP, reveals the following "Default Gateway":
82.169.255.254.  See list below. Could this be the 'gateway'
information we are looking for?

This is a good point. However, the codes 'address' and 'netmask'
consist of figures revealed by ifconf-tests. Even the names like
'eth0' and 'eth1' have been revealed by networkmanager and different
tests running via terminal.

The  name of the device is 'Zyxel Prestige 2000 series'. It is a
router which is the connection between my ISP and my computers. The
router has 4 access points for RJ-45 connectors and cables.  The 'Web
configurator' of this modem reveals the following technical basic
information:

System Status

Yes - the desktop PC from which I am sending this message.

Recently, I did use the cable between 2 other devices - it functioned
at that moment. It is a new cable, bought only  few months ago.

However, I am not really sure whether the RJ-45 access point of my
laptop is adequate. That is why, I also examine another way I can use
this cable: to connect it to a ethernet PCMCIA card, with a special
ethernet RJ45 interface. This results in a connection 'eth1' according
to both KNETWORKMANAGER and pppoeconf. According to KNETWORKMANAGER,
the connection status of eth1 at the laptop is 'active' now. However,
the pppoeconf test for eth1 also fails. Also via a browser, I do not
manage yet to reach internet from the laptop.

Thanks everybody for all your efforts so far. I have to leave now for
an appointment. I will come back and resume this technical work on
Sunday.

Respectfully Yours,

Bas Roufs.
