[driverloader] Getting lost setting up a Realtek card

Disclaimer: this is probably down to me not knowing anything about
wireless networking, rather than anything specific to driverloader,
but I haven't had responses elsewhere...

I am trying to get an ad-hoc wireless network working, but don't
really know what I'm doing! Guidance appreciated!!

Currently I have working:

	internet <----> Linux box <-- crossover cable--> Win XP laptop

What I want:

	internet <----> Linux box <--    wireless    --> Win XP laptop

(The internet connection is blueyonder broadband through eth0.)

The wireless card in the Linux box is based on the Realtek 8180
(rtl8180) chipset. (Its an Edimax PCI card,

The card appears to configure OK, but the driverloader FAQ assumes you
know what you are doing in setting up a wireless network, and only
fills in the specifics of "how do I do task XXX with driverloader" -
when I don't know what steps I need to take! This is all made worse by
the fact that the other side of the link is a Win XP box, and I know
nothing about administering it! (Used Windows sporadically - ie, once
every few weeks on a dual boot machine - over the last decade!) The
price of being almost Windows free for so long is I now can't use the
**** thing! :-)

Sadly, I'm in the situation where I don't really know what questions
to ask... sorry! Responses along the lines of "have you done XXX? What
messages did you see?" would be most appreciated!

On the Linux box:
	eth0 is the internet, IP via DHCP
	eth1 is the wired interface, IP, which is working
	eth2 is the wireless interface, IP, which is not working

On the Win XP laptop:
	the IP of the wired interface is
	the IP of the wireless interface is

Here's the output of various commands - I don't know what is relevant
and what is not, so apologies for all the redundant guff:

Other stuff: driverloader is currently version v1.56, license is the
free trial - due to expire in a couple of days. I'd like to get this
working before then so I can buy with confidence! :-)

System is currently Mandrake 9.0, though migration to Mandrake 9.2
