Linksys Wireless Router 2.4-GHz, Ubuntu, not working

Hi, I've just bought a Linksys Wireless ADSL Router, attached it to my
laptop via RJ45 cable, setup and all working fine! However, although I
can see the SID being broadcast, it's telling me connection failed --
I have put in the correct WEP key as per the router administration but
it's still not working. I've tried everything but can only get online
via the hard-wire cable

Right, further investigations. I have disabled the WEP key and allowed
anonymous access and it's still telling me connection failed? any
ideas? Thank you

What does iwconfig say?
And "iwlist scan ..."?

So at least it sees the access point.

I should say that I'm no expert.
If the access point is using dhcp,
I would look at this,
eg by looking at /var/log/messages on the remote machine
(or possibly on the access point, if this is running Linux),
and also /etc/dhcpd.conf .

Is the ESSID definitely correct?

I'd look too at /etc/sysconfig/network-scripts/ifcfg-eth1
to see that the settings there are correct.

I'm not sure really, I just click on the network icon, select the SSID
and click connect, and it says connection fails. This is with my new
linksys router -- it worked fine before with the BT Broadband Hub we
were originally using. So I figured it must be the Linksys hardware
configuration, but on disabling authentication and allowing free
access, it's still not working -- i'm stumped.

As I said, I am no expert,
but how do you know the access point does not have an encryption key set?

I have a LinkSys WRT54GL.
I can access this over the web and set or unset the ESSID and key.

Also, are there any dhcpd entries in /var/log/messages
on the remote machine?
