has my wifi security been compromised

I use wpa tkip on my router and today see an extra entry on the dhcp list
that isnt any of my own systems.

Has someone gotten past the security or does the router give an ip to any
system that tries unsuccessfully to connect?

Thanks

It won't assign an IP to something that doesn't authenticate.

It's normal that it only gets an IP address after authentication , though
you can verify this by trying to connect your laptop with an incorrect
preshared key and check.

Time to change password to something much longer and more complex I think ,
and if you can change settings about how often the encryption keys are
changed do that as well

Don't some implementations of DHCP client assign themselves a temporary
address for the purpose of making the IP request? 169.254.x.x range is
reserved for this - although this shouldn't show up on the router. Most
router web interfaces will allow you to see the MAC address of
any 'foreign' clients

Is it also possible that a nearby unsecured router could be handing out
IPs?? Like you said best to check with the laptop set up incorrectly to see
what it does.
