How can I configure a static IP from my Linksys router?

Discussion in 'Wireless Internet' started by laredotornado, Mar 10, 2007.

  1. Hi,

    I'm running a LinkSys wireless router, WRT54GS, firmware v 4.70.6.
    Someone on this newsgroup said it would be preferrable for me to
    configure my static IP on my router instead of on the machine
    directly. I like this idea, but I don't know how to do that with the
    above router. Is it possible? How is it done?

    Thanks, - Dave

  4. I don't have that router, but on many routers, you can tell the DHCP
    server to assign an IP to a MAC on a semipermanent basis.

    On my DLink its called Static DHCP clients and you select a MAC to
    link to an IP address.

    On my old SMC router, you just set the lease time to infinity, or the
    largest possible value, which amounted to the same thing.

    On my even older USR, it was something similar again.

    You can set up the router to use a static IP instead of a DHCP IP that
    the router would get from the ISP's DHCP server. That would require that
    you contact the ISP to get the static IP(s) from the ISP to configure
    the router to use the ISP's static IP(s) instated of the ISP's DHCP
    IP(s), if the ISP gives those IP(s) out.

    You can't configure the router to give out static IP(s) to client
    machines. The client machines with their NIC's must obtain/use a static
    IP on the router, just like the NIC's would obtain a DHCP IP from the
    router's DHCP server.

    DHCP IP(s) on the Linksys router normally start at 192.168.1.100 to the
    DHCP Issue Count. If the count is 10, then 192.168.1.100-192.168.1.110
    are DHCP IP(s) that the DHCP server on the router would issue to
    machines requesting a DHCP IP from the router.

    192.168.1.2-192.168.1.99 and 192.168.1.111-192.168.1.255 are the
    router's static IP(s) not issuable by the router's DHCP server.

    To use a static IP on the router, the O/S must configure the NIC to use
    a static IP on the router.

    So, you equate what it's telling you about Windows and you configure the
    Linux machine's NIC to use a static IP on the router.

    One other thing, the DHCP server on the router assigns the NIC's MAC to
    the issued IP in the router's DHCP table. Most likely, the machine is
    going to get the same DHCP IP assigned to it on a small network, which
    is kind of static, unless you force a new DHCP IP to the machine.
