Force router IP assignments on LAN

My router (Linksys BEFSR41) sits between my two XP PC's and my cable (DHCP)
modem. I have assigned the router the IP 10.10.10.1, which in turns assigns
IPs to
my PCs, typically 10.10.10.100 and ...101, upon connection. The router
makes the assignment of PC IPs -- as far as I can see -- by which PC
connects first - this one gets the ..100 assignment, and the last gets the
....101.

Is there any way I can force the router to assign specific IPs to specific
PCs, regardless of which PC connects first?

Thanks you.

Regards,
Sigurd
 
Yes, You can do MAC address control or Fixed mapping.

Many routers have the capability to reserve a specific IP address for a
computer based upon the adapter's MAC address. Don't know whether a BEFSR41
can do this - check the manual. If you do not have this capability, turn
off DHCP on the router and manually assign the address, DNS, and gateway on
the computer's Local Area Connection. Shouldn't be a hassle with only 2
machines.

Check the router documentation to see if it has a way to specify the
DHCP IP address for a particular computer, probably based on the MAC
address of the computer's network card.

If it doesn't, you can assign static IP addresses to your computers,
bypassing the router's DHCP server. If you do that, be sure to
specify 10.10.10.1 as the Default Gateway and your ISP's DNS server
address as the DNS Server.
