    Noticed the last number on the admin screen 192.168.1.1 is different
    than what is on the bottom of the actual Linksys unit.

    Strange.

    Guess it does not matter since I am using MAC filtering back to that
    box. Hope Range Repeater is the same..... Funny....

    Anyone else see this on their router MAC address (underneath unit
    versus what is on admin screens)?

    It doesn't matter because the MAC addresses in question are the one's
    on your WRT54GS. You don't filter your own MAC addresses, just those
    of the connecting devices.

    Your mysterious "range repeater" (whatever make and model that happens
    to be) *MIGHT* require a MAC address to operate, but more likely just
    requires the common SSID.
    That's normal. The MAC address of the wireless and ethernet ports are
    usually different. Using DD-WRT on a WRT54G v3:

    ~ # ifconfig | grep HW
    br0 Link encap:Ethernet HWaddr 00:13:10:8C:14:A9
    eth0 Link encap:Ethernet HWaddr 00:13:10:8C:14:A9
    eth1 Link encap:Ethernet HWaddr 00:13:10:8C:14:AB
    vlan0 Link encap:Ethernet HWaddr 00:13:10:8C:14:A9
    vlan1 Link encap:Ethernet HWaddr 00:13:10:8C:14:AA

    What the various port names really mean:

    Sorry. Made a mistake. The Linksys WRE54G range extender is the device
    that shows the LINK ID on its admin screen when the last digit does not
    match that of the WRT54GS.

    So in other words the bottom of the WRT54GS has a mac address that lets
    say ends in 7.

    The WRE54G Range Extender displays what I think is the ID of the
    WRT54GS router and its last digit is a "9".

    Thanks, Patty

    Yeah, that's normal. The ethernet ports have a different MAC address
    from the wireless port. I've never bothered to check if the MAC
    address on the serial number tag is that of the ethernet ports, or the
    wireless port.
    Not a problem. If you're not sure which to use, just:
    1. Connect to the WRT54GS via wireless (without the WRE54G). Make
    sure your computer is NOT also connected via a wired ethernet
    connection.
    2. Open a DOS window and run:
    Start -> Run -> cmd <enter>
    arp -a

    You should get a list of MAC address and IP address pairs. The one
    next to 192.168.1.1 is your router's MAC address. For example.

    arp -a
    Interface: 192.168.1.11 on Interface 0x1000003
    Internet Address Physical Address Type
    192.168.1.1 00-0c-41-71-36-30 dynamic
