newbie question on device lists

    I'm new to all of this, but I've managed to flash ver. 1.21 on my WRT54GL. I've configured it and have my wired machines assigned static dhcp. However, when I look at the device list, I routinely see three entries with the mac address of my primary machine. One has the staic IP i assigned, and the other two have ips from the dhcp pool. I don't understand how this is occurring, if all of the entries weren't on the br0 interface, I'd think I was being hacked, but I just don't know. Any thoughts?

    Microsoft Vista with ipv6 enabled? This has been observed before!

    No, I'm running XP SP2. No Vista on the network.

    Now that you've got the devices set up for static DHCP, have you given it a chance for the now unused DHCP licenses to expire? Can you try deleting them? Reboot the router and see if they don't disappear.

    Second idea, when you set up the static DHCP for each device, did you choose different IPs outside the normal DHCP range (i.e. .100-.149)? Could be a conflict there, and that's why it's always good practice to assign static IPs outside DHCP's range.

    The extra entries come up, and I can delete, or maybe terminate their lease is a better description, but eventually they come back (like next day). I've rebooted and it doesn't seem to make a difference. Also, my static IPs are in the dot 1-10 range, while DHCP is in the dot 100 - 149 range.

    mstombs mentioned that this was seen with Vista, what was the resolution for that case, maybe it will work with XP?

    Normally I cure it with Vista machines by uninstalling IPv6 (and anything else that isn't used).

    I sometimes get up to 25 or so user IP's all using the same MAC address belonging to one user using Vista. Anyone know why? Usually when this happens and I can't contact that user, I kill off the original machine with that MAC using Netcut, and after a while everything returns to normal.

    Not that this helps you much, although it is a similar problem, and seems to involve some mechanism on the client machine.

    Comment about Vista :frown:

    I've had many problems with users using Vista , seeming to have several device drivers for various nonexistent modems, bluetooth, infrared, firewire, etc. and also several unused protocols being installed. The point seems to be reached when the OS stops working with the wireless router, it can't seem to find and use the right driver/protocol. I have tried to identify exactly what is happening but there have been just too many variables. Not helpful is also that since Vista seems to be so slow on the offending laptops, the owners tend to keep clicking everything again, opening many copies of the same application, until the whole thing becomes unstable.

    EDIT ...

    Just a thought - you aren't by any chance using a "Vista Transformation Pack" with XP? Some of them do install IPv6 by default, along with a lot of other stuff. These packs cause many problems here. I guess not or you would have mentioned it ... but ... ?
