otherwise who knows what it could be, hopefully not someone on my network that shouldn't be.

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.

In your Network settings, choose Wi-Fi from the left-side menu and click Advanced in the bottom-right corner of the window. 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. On Mac, click on the WiFi icon in the menu bar and choose Open Network Preferences. I think those power meters connect to cell phone towers anyway, so doubt it somehow got onto my WiFi network by itself. 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. The power company recently put in a new digital wireless power meter, so I'm wondering if that's it. Screenshot had this happen before.Nothing to to a neighbor. An unidentified router recently appeared on my network. Here's their website, which shows the products they make (look under 'Products'. RECOMMENDED:If you have Windows errors then its highly recommended that you download and install this Windows Repair Tool. I did some searching on the 'net and found that the device traces back to the 'Wistron Neweb Corporation'. 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 even ran ipconfig /all in a DOS window on both my computers and didn't see this MAC address. 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. It shows up as: Unknown 30:14:4A:xx:xx:xx I accounted for all the MAC address (by verifying them against my devices) except for one that shows up. 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 went into my modem/router user interface today to look around at my settings and to check for any firmware updates.
