Strange WRV200 Behaviour

    Here's a copy of an email I just sent to Linksys. I thought maybe someone from this forum may be able to explain it (or even confirm if they have heard of it).


    I notice something weird when scanning my wireless network traffic. It seems whenever I power the WRV200 on, there are two ESSID's associated to the router MAC, one is my own SSID and the other is "Harrison". Harrison always has a client MAC of 00:04:20:06:40:c0 associated with it (again, Harrison seems to be a second router ESSID that uses the exact same MAC as my own). The client MAC prefix 00:04:20* is registered to SlimDevices Inc (which makes the Squeezebox Media Centre). I know for sure that this is related to the router as when I power down, both my own and the Harrison ESSID go away, power up and they come back. I am using WPA2 and have changed the PSK several times and the associated client to Harrison always authenticates with my WRV200 MAC. Further, I have MAC filtering disabled and the 00:04:20 address is definitely not on my list. Very weird, I'm downloading your source code to have a look at it and see if it sheds some light. Are you able to explain this???

    Should say "MAC filtering is enabled" cause it is.

    what happens when you reset the wrv200 to factory defaults and setup the router again manually? perhaps whatever you are scanning the wireless network with(?) is perhaps arping the mac address to another known name perhaps? just a thought
