Fixed network IP addresses

    I have three computers connecting to my router (WRT54Gv5). One desktop (connected directly to the router), 1 laptop (wireless) and another desktop (wireless). I want the two that connect wirelessly to the router to have the same (internal) IP address all the time.

    Is this done through the MAC Filter? If so, is the order of MACs in that list determine the IP address?

    Its done at each computer, not the router.

    Some routers support "static DHCP", but this is the best way to do it.

    -Open "My network connections"
    -Right click on the LAN connection and select "Properties"
    -Select "TCP/IP" and click "Properties"
    -Set IP's within the same subnet, but outside the DHCP range

    Some routers support what's called "Reservations" DHCP. That's where you plug in the MAC of the PC you wish to make static..and enter the IP you wish to give it. I don't believe stock Linksys firmware for the v5 offers that feature though.

    Here's a quick little guide..

    Pardon me but, why? I'm having a hard time fathoming an ordinarily useful reason for having more than one host with the sam IP address.

    Im pretty sure he doesn't want two comps to share a common IP, but rather have each one have a unique one that it recieves all the time.

    exactly kg4mrv. Would I use the same DNS entries you have in that screenshot?

    if it's not done at the router level then I will find out from a fedora board how to do it.

    Try 3rd party firmware like dd-wrt. I'm using it right now on all 3 of my laptops. They have that feature you're looking for. BTW, it's called static DHCP

    On what grounds? that it doesn't support DHCP reservations :roll:

    You might be able to use, but if that doesn't work look under the status tab on the admin page, and use these DNS servers.

    So I have set:

    IP -
    Subnet -
    Gateway -
    DNS -

    However now I cannot access the router. When I try to access, the password dialog box appears. After that the screen goes blank.

    I am able to access the internet though

    Oh. Just needed to reboot the router.

    I've recently upgraded the firmware to DD-WRT v23 SP1 micro. To setup a MAC address to have a specific IP you go to Administration --> Services.
