wireless intruder?

Hopefully I am posting this in the correct group.

I am a new DSL user and my router has wireless.  I have noticed the
the wireless connection light is always on steady.  According to the
user guide that indication means a link has been established. When I
look as My Network Places to see who it might be, all I see is my own
computer and my other computer located elsewhere in the house. Yet
even when my other computer is off the light remains steady. I have
set my router no to broadcast the SSID and the firewall is set to
medium.  How can I 'see' who else is connected?

Do you have encryption turned on?

Thank, I'll take a look at airsnare later today. Unfortunately I need

The easy way to detect this is to change your wep key, and if it isn't
128 bit make it that too.

I would look at the active DHCP leases on your router if it supports
it, or if your using a external DHCP server look at that.   If you see
more then the the two pcs you have connected then you found him.

A third way is to use a port scanning program to sweep the ip range
pinging all the pcs or better yet looking for open ports.  The scan
for open ports ignoring a ping request may find it if they have echo
requests blocked on their firewall.  The one I like to use is NMAP,
that runs under linux.  The only program off the top of my head that
will run on win2000 that will do it is GFI langaurd security scanner.

The command line version of NMAP also runs on Windoze:
  http://www.insecure.org/nmap/nmap_download.html
There are a bunch of Windoze GUI front ends for NMAP:
  http://seclists.org/lists/nmap-dev/2004/Jan-Mar/0091.html
  http://seclists.org/lists/nmap-dev/2004/Jul-Sep/0041.html
  (etc...)
but I don't use them.

Not to be too simplistic but does your routers configuration pages not have
an "attached devices" section?

I have changed my WEP from 64 to 128-bit.  The indicator flashed and
then went back to steady. DCHP shows only my pc and the remote PC.
I did try some of the recommended detection software and no other
system was seen.  It's quite possible that the indicator really means
that the router is transmitting.

Thanks to all who came to my aid.

The wlan light should be on steady. This means the system is ready and is
waiting for a connection. Once a connection is being made the light should
blink, meaning a connection is being made. The light should also blink when
you are accessing the net.

Hope this helps

I didn't catch which wireless router you have, I have a WAP54G hooked into
my router and whenever my router is on, the link light is on the WAP telling
me it has established a link with my router, not necessarily meaning a pc. I
would pay more attention to how much the link light flickers. just a thot.
hope this helped.
