Wireless Woe - Please Help

I'm trying to connect my pc to my router unsuccessfully for a couple of
days now and have run out of ideas. Perhaps somebody can help me along.

I'm using a linksys WMP54G PCI card; the router is a linksys WRT54G. My
OS is debian based Elive 1.0 (GEM) which uses a 2.6.18 linux kernel.

Here's what i've done so far:

Initially i tried the out of the box native rt61 driver pre-installed by
Elive, which did not work at all (the wmp54g couldn't see the router).
Next i used ndiswrapper. This would seem to have been reasonably
successful. The driver and PCI card seem to be working and can see my
router. I've put the outputs of

1. $ lshw -C network
2. $ ifconfig
3. $ iwlist wlan0 scan
4. $ iwconfig

at the end of this posting. However when i try to connect with

$ dhclient wlan0

all i get is:

This is while trying to connect to an unencrypted network! So the
problem has nothing (yet) to do with wpa.

Any help appreciated. Here are the outputs mentioned above:

Are you sure? iwlist wlan0 scan results say the encryption key is on.

yes, i have a second pc connected to a wireless bridge and am therefore
turning encryption off only for short times. When generating the output
for my posting, i had encryption on again, but i can assure you that the
dhclient command produced exactly the identical results as posted when
trying to connect to an unencrypted network.

hmm, sorry for the identity confusion - also a consequence of working
from different pcs. I'll keep posting as EliveUser in the near future ;-)

Any other protections at the router? Do you have to add the mac
address? What iwconfig command are you giving? Have you tried "iwconfig
wlan0 essid "Meinert" ? Sorry, my experience is limited.

No it is not. If you look at the output of iwlist s you see that the
network with essid Meinert has encryption on, and the output of iwconfig
shows you are trying to connect to Meinert.

And what else did you post that is not true? You want help but then post
stuff you know is wrong.

Are you really sure that there is no encryption key? Switch it off and
leave it off. You are not going to bombarded in the day that you use.

Fix one problem at a time.

b)Try with a fixed IP address instead of dhcp. Maybe dhcp is badly set up
on the router.

Make sure that in the Kernel-config CONFIG_PACKET is set.

I wasn't aware of that when i first posted it. Why do you assume so?
Anyway, i went through the whole procedure several times with encryption
turned off and with the same result.

Tried that, same result with a static IP address as well. The router
works fine and assigns IPs to several other gadgets in my network, so i
would assume the problem must be specific to how the wmp54g communicates
with the router.

yup, the pci card knows which essid to connect to. The router broadcasts
the ssid and it doesn't try to hide the mac address either...
