    i have mac filter enabled, set up as reject, to force certain wireless clients to certain AP's.
    googling suggests it has something to do with intra-lan dhcp. as mentioned, i only have one dhcp server, at the main router.
    the device is only there sometimes. when it is there, it appears to be on both AP's and bridges that connect to them...

    Strange indeed. Hopefully Shibby can figure how to fix that.
    Looking at my device list, I got no information for column "RSSI, QUALITY, TX/RX Rate" for each attached devices. Is this a bug?

    I think that is off line (DDNS) Dynamic DNS update address

    that's interesting - but only my gateway router is set for ddns.
