Do you have a Wii? Or maybe an iPhone or other similar device? Or a
network printer? There is a fair chance that the other client is
something that should be there that you've just forgotten about.
However, there is also also a reasonable chance that it is a security
breach if you are running an unsecured wireless network.
What I would recommend is that you probe the unknown device with
something like nmap (available from ports security/nmap) with
nmap -O -sV IP-ADDRESS-OF-MYSTERY-DEVICE
That should give you a fair amount of information about the device.
