I have a DLink DI-524 router that keeps assigning an IP to my laptop (running XP) every 3-8 seconds. I also had another laptop and a wired desktop attached but I have since then taken them out of the equation. I haven't set up any encryption or other security yet because I am having this problem. I have narrowed down my DHCP private IP list to 192.168.0.100-103 (because I have 3 computers) but this doesn't work either. Any ideas?
I am using a shared key.

I also have a D-link router, and what I do is to assign static addresses to all of my computers (which helps in quite a few ways, unless you have a large network). The settings for this in my router, which should be almost the same as yours, are in the same DHCP configuration where you can assign your scope. You'll need to set up your MAC addresses under the section that says "Static DHCP" (a concept which to me, makes no sense at all. Static dynamic? What?)

Anyway, add entries for all of your computers by their MAC which can be found under windows by bringing up a command prompt and typing ipconfig /all, then give them an IP address, and hopefully that'll fix your problem.

You could also set up your Windows not to use DHCP at all. Just give it an IP outside of that DHCP range. IP: 192.168.0.x, mask: 255.255.0.0, gateway: 192.168.0.1, DNS server: 192.168.0.1... That should do it.

I have tried statically assigning private IP's to all 3 computers on my network but the router will assign a different IP to each computer. It makes no sense at all. You can see the computer and it's MAC in the static list, yet underneath in the DHCP list the same computer has been given a differnt IP. I have checked to make sure that I have spelt the host name correctly aswell as the MAC address and everything is correct.

limey, are you setting the router to give out static IPs (on the server side), or are you setting up static IPs in Windows (on the client side)??? The former is what glytch suggests, the latter what I said.

I guess that if you use my method, and get rid of DHCP altogether, you'll solve your problems. Basically, your router should only give out IPs to those computers that ask for one; if you're not asking, none should be given. Hence the (supposed) logic of my approach.

But if you think/know I'm wrong, please say so, and describe why.

I don't have D-link, but when I set up my Linksys router, there's usually a option if you scroll down all the way down to the end of the page, to save changes. Is there an option like that?
