need to assign specific ip address to pc's

hi all. im getting tired of this one problem. i have 2 pc's and an xbox 360. all 3 are online here and there. sometimes though, i noticed the ip addresses change. one day, my pc will end in 100, the other in 101, and the xbox in 102. another day, they will all end differently. like the xbox will be 100, pc1 will be 101 and pc2 will be 102. i need to somehow make it so that pc1 uses 1 ip, pc2 uses another, and the xbox uses another. i need these to stay the same despite if they are online or not. i hope im making this clear and that someone can help. linksys wrt54g v5. thanks.

Re: need to assign specific ip address to pc's


What you want to do is to assign a fixed LAN IP address to each computer and Xbox.   Linksys has some specific rules regarding fixed LAN IP addresses, most importantly, they must be outside the DHCP server range, and they cannot end in 0, 1, or 255.
 
Here are the full set of rules:

With Linksys routers, a fixed (static) LAN IP addresses must be assigned in the device that is using the address. So you need to enter the fixed address in the computer or printer, not in the router.

When using a Linksys router, any fixed LAN IP address must be outside the DHCP server range (typically 192.168.1.100 thru 192.168.1.149), and it cannot end in 0, 1, or 255.

Therefore any fixed LAN IP address would normally need to be in the range of
192.168.1.2 thru 192.168.1.99 or
192.168.1.150 thru 192.168.1.254
assuming you are still using the default DHCP server range.

Also, in the computer, when you set up a static LAN IP address, you would need to set the "Subnet mask" to 255.255.255.0 and the "Default Gateway" to 192.168.1.1 and "DNS server" to 192.168.1.1

It is also important that no two devices on your network be set to the same static LAN IP address.
