XP computers no longer see Wireless Signal

[Lostguy6]

Im hoping someone can give me some great insight on what to do with this issue, I've looked around online and can't seem to find what specifically matches my situation.

Here's the issue, I came home from my training (hooah army!) and I'd purchased a new laptop while away. When I got home and started using my desktop again, I started recieving messages of IP conflicts between the two computers. I just clicked off and ignored, and now my desktop (XP) wont connect to the wireless signal, it wont even see it. it sees some other one in the neighborhood, but not the house connection, but my laptop(vista) as well as my fathers (vista) both see it, the host computer which is an XP desktop only reads the hardline, if any of this makes sense.. any ideas?

Repair duplicate IP address on network issue.

1. Turn off everything on the network, ALL the machines and any other network device like network printers and NAS drives.
2. Turn off the router and modem.
3. Turn on the modem, wait for a steady data light.
4. Turn on the router, wait two minutes.
5. Turn on the network devices and computers, one at a time.

This issue is usually caused by resetting a router without resetting all the network connected devices.

Another issue that will cause duplicate IP addresses is assigning static IP addresses to devices that conflict with the router's DHCP address range. If you require static IP addressed devices on the network, they should be configured to be in the same subnet but outside the address range defined for the DHCP server.
