OT: Any network and Mac gurus out there?

I would:

1. first try with the built-in ethernet card (can't you check it for
example with a printer if it is OK?),

Since I thought the built-in card was toasted due e.g. thunder, I
installed an external card. But the Mac is refusing to see the new one,
it insists on the built-in. So, I assume it does that because it finds
nothing wrong with the built-in. This leads me to believe that the
problem is caused by something after the Ethernet plug, i.e. either in
the cable to the modem, the modem's in port (hardware issue) or the
software inside the modem.

2. check in the preferences>Network>NetworkConfiguration_menu (in OSX
10.3, in 10.2.8 should be similar) if ethernet is checked and if it is
in the firs place (at the very top) - if your brother is using a dial
modem, this option could be left at the top and the Mac just tries to
connect with it and not DSL (once I made this mystake),

I've checked that, and even removed the dial-up option once.

3. try intead of connect automatically, to type the name of the network
(for example my ethernet modem by default had the name WLAN) in the
preferences>Network - just to see what will happen.

I'll try that.

Is there any message in the preferences>Network>NetworkStatus?

Nah...as I recall (I'm home at my place now), I got no strange messages.

Sorry that can't help more.

No worries, you've been very supportive. I'll drop by my brother's place
later today with some new ideas:

A new, working (and tested) ethernet cable
I'll reboot the modem while the computer is shut off.
I'll test some configurations
I'll test your suggestions

Cheers,

Nope.
It seems as if the modem isn't co-operating.

Is there something (a message) in the Preferences>Network>Network_Status
menu?

You should see the current status of each activ art of network
connection, also for the ethernet if the cable is attached. This may
give you a hint about what is happening.
