Weird problem with DHCP on a home router

Alright, here's the jist of my problem. I have two home computers hooked up to a linksys 4 port router and switch, and everything was all good. I had the DHCP set up to give my livingroom comp an ip of 192.168.1.101, and my bedroom one to be .100 . Anyways, the nic in my bedroom comp went, so I replaced it with another of the exact same namebrand and model.

The problem is that now my router will not set the bedroom comp to .100, it can not find it. If I tell it to assign it any other number, it works perfect. Normall, this would not be a problem, but when I try to enable DMZ it now only allows that at ip .100 as well. Is it possible for a router to somehow bond I guess with a nice and make that IP unusuable?
 
have you reset the router? also, reset the cable modem or DSL or whatever..it's not uncommon for IP's to bond with Nic MAC addresses
 
I've reset the router, but haven't tried the cable modem as I was under the impression that because it was dynamic it reset itself every so oftem... I'll give it a shot, thanks
 
Your ? makes no sense. If you are using DHCP you do not assign a IP to the machine you let the router do that. The only way that you can assign a IP to a machine when using DHCP is to set the range of IP's for DHCP above 100 and assign the static one outside of that range usually starting with .10
Bleep
 
Sorry, I thought I had made myself clear... I had set the range of the DHCP to start at 100 and go up so that I could control the ip address in a nice sequence.
 

Assuming that your private IP range is 192.168.1.0/24 with a DHCP range that is greater than 192.168.1.99.

If the above is true than you may have a conflict between a static IP of .100 & a DHCP or .100. You can try lower the static Ips of the computers in you LAN to less than .100, or reset the computers Network setting to DHCP.
 
One other thing is make sure that you have set the router to have at least 1 more IP than you have machines on the router. You can keep the same IP's on the same machine's by booting the machines in the same order every time.
