    I've been running Tomato on my WRT54GL for about a week now, and I really, really like it. QoS actually works! Suck on that, dd-wrt!

    Anyway, I noticed something weird in my device list. Attached is a screenshot of it.

    The last device says it's connected to eth1, but has no IP address or name, and the quality is maxed like it can only be the wireless radio in my router.

    However, when I ssh into the router, and do an ifconfig eth1, the MAC address of the eth1 interface is completely different. It starts with 00:18:F8, which OUI says belongs to Cisco/Linksys, which makes sense. This also agrees with Advanced->Mac Address's listing for my wireless radio.

    If I click on the link for the MAC on the device list to do the OUI search, it says that 00:30:BD belongs to Belkin. I have no Belkin devices on my network.

    I am running WPA2/AES with a randomly generated 63char key...so it's pretty unlikely that somebody else managed to connect to my wireless LAN.

    I tried resetting the router to clear up any random devices I may have connected (I did some wireless bridge testing, etc, with some other routers...none of them Belkin) and the entry persists in the device list.

    Thoughts?

    I've had that on my router occasionally. Not sure what it was but it disappears after a while.

    If I turn wireless filtering on, it goes away immediately...so it would appear it's some sort of external connection. It would be nice to be able to figure out what it is, though.

    Try sniffing around with Network Stumbler, and if you want a challenge WireShark :)
