I went into my modem/router user interface today to look around at my settings and to check for any firmware updates. I was also going to setup MAC address filtering, and when I enabled MAC filtering a pull down shows up that lists all the MAC addresses that the modem can currently see (both hardwired and WiFi devices). I accounted for all the MAC address (by verifying them against my devices) except for one that shows up. It shows up as: Unknown 30:14:4A:xx:xx:xx
I also noticed that if I sat there and updated the list for a while, that this MAC address would disappear and reappear at times. Thought that was strange.
I even ran ipconfig /all in a DOS window on both my computers and didn't see this MAC address. Only weird thing I found doing the ipconfig /all command was 4 instances of a "Tunnel adapter" (described as "Microsoft ISATAP adapter") all with the same MAC address (00-00-00-00-00-00-E0), but it says the "Media state" is 'disconnected'.
I did some searching on the 'net and found that the device traces back to the "Wistron Neweb Corporation". Here's their website, which shows the products they make (look under "Products".

The power company recently put in a new digital wireless power meter, so I'm wondering if that's it. If so, how did it get on my network without someone putting it there knowing my network SSID and passkey? I looked at the face of the power meter and didn't see any kind of MAC address info. I think those power meters connect to cell phone towers anyway, so doubt it somehow got onto my WiFi network by itself.
Here's a thread I found where someone else noticed the same thing of having Wistron Neweb Corporation MAC addresss show up, and they say they didn't install anything like that.

Is it possible that one of my devices has more than one MAC address and I can only see one of them? I'd like to account for this MAC address if possible ... otherwise who knows what it could be, hopefully not someone on my network that shouldn't be.
Any ideas on this?
