Indeed.

I'm not knowledgeable enough to sort that out.

Have already done everything a simple human being can think of: power 
off the router, reset the router, disable DHCP and enable again.

While I am typing now, and while laptop and PC are truly connected to 
each other and both as well to the Internet (thus wlanstat set to use 
manually 192.168.2.102) , the DHCP log of the router shows:

ip=192.168.2.100   mac=00-A0-24-7C-8D-33   (= main pc 3com card)
ip=192.168.2.101   mac=00-02-2D-30-D2-FB   (= mac address jacaranda card)

Hmm, may I remind you, before you bothering all, I already have done the 
obvious, that is:

just the Artem driver in the config.sys
just in setup.cmd: dhcpstrt -i lan0 and the loopback etc.

Should have worked, shouldn't it?

But the answer was "dhcp server didn't get parameters".

The same exercise with the Genprism drivers do give exactly the same 
result ""dhcp server didn't get parameters".
It is always like that when dhcp is set to a wireless lanx (jacaranda). 
OTOH, dhcp works as it should when set to a wired lanx (onboard intel nic).

I have checked with Frank Vos, he has exactly the same card as I have, 
and at his Laptop, a T23 IIRC, DHCP is working with Artem drivers as 
well as with Genprism (remember, Artem drivers don't work here at all, 
except for the flashing lights).

I still wonder whether the internal wireless nic (intel) of my T41 
couldn't be in the game. After all, there is no option in the bios to 
disable the intel onboard nic. Meaning it is always powered on. A 
radiating device that is powered on, always radiates, doesn't it?
