My question goes like this, I have a Linksys WRT54g wireless router running DHCP for my home network that has 3 computers and an XBOX 360.
Periodically and pretty recently my router will assign one of the computers 4 ip address. The MAC address is the same. One time i noticed 3 addresses has the exact lease time duration remaining. Then other times they are all different. I guess I am asking if there could be a major malfunction within the router.

How can you tell that this is the case?

Can you ping all four addresses?

Are you using MAC address filtering as a security measure for your wireless network?

Do you have three neighbors who are hackers?

When you reboot the router, do you hear some loud cursing from a nearby house?

Either your router is hosed, the screen you are looking at is lying to you, or you have multiple uninvited guests on your wireless LAN.
