    Hi, I've searched on the forums and couldn't find an answer to my question. Is it possible to see, real-time, the current MAC addresses that are trying to connect wirelessly?

    The reason for this is that I have determined that there is a device on the network with a broken network card. I now need to isolate this device and contact the person who owns it to take it off the network permanently or fix the device.

    Accessing the router through console yields lots of frame errors:

    # ifconfig eth1
    eth1 Link encap:Ethernet HWaddr 00:13:10:xx:xx:xx
    RX packets:14289 errors:0 dropped:0 overruns:0 frame:1516
    TX packets:11581 errors:106 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:100
    RX bytes:13576232 (12.9 MiB) TX bytes:5955316 (5.6 MiB)
    Interrupt:4 Base address:0x1000

    This is only running for about 15-20 seconds. I got up to 40,000 - 50,000 frame errors once I became aware of the problem. I am sure it was higher, but I reset the router several times (via soft reboot). This also ate up the router's memory, taking it down from my normally 16mb free memory to around 8mb, as well as slowing all connections down to a crawl.

    I have since completely disabled wireless on the router, and instructed everyone to use a hard line/ethernet connection. Any suggestions or background on this problem is welcome.
