Unrecognized device on my network

My wireless network is set up with WPA2 security and a 50+ character, random password. My understanding is that's pretty secure. Also, the router is in our basement and a decent signal is hard to get more than a few yards from the house.

Nevertheless, I was browsing my network this morning (Windows Explorer) and noticed an unrecognized device under "Other Devices." It was called "Blaze" and the only other information I could find about it (via Right-click -> Properties) was that the model number was "wl12xx" which appears to be a generic wireless driver from Texas Instruments. Whatever this "Other Device" was, it disappeared within a couple of minutes.

Due to a router misconfiguration (my fault, not a hack, and since fixed), I wasn't able to check the DHCP or wireless connection logs so I don't have any data other than what showed in Explorer.

I can see a couple possible scenarios:

1.) My wireless key was somehow cracked and an unauthorized device did in fact join my network.
- or -
2.) My computer (or other device on our network - Android phones, a Brother printer, and Dlink camera) has something on it that acts as a separate network device on occasion.

I would appreciate any insight as to what this "Blaze wl12xx" could have been, as it was definitely there for at least a couple of minutes that I know of.

Thanks in advance,

Matthew
 


No, we only have one tablet (an old Motorola Xoom) and it was accounted for.

Since posting this morning, I noticed an LG Optimus also listed in my network - another device we have never owned and that has never been authorized to connect.

The funny thing is that both devices disappeared within a minute or two of me right-clicking their icons in Explorer to view more information.

I'm no networking expert, but I'm no newbie either. This has got me totally buffaloed.

<edit> Two minutes after posting this and an RCA tablet shows up, then disappears when I check it out. None of these devices are showing an IP address (whereas my known network devices do). </edit>
 
This literally just happened to me as well, I was about to connect to my other computer in the house and i seen the "blaze" client connected to my network. I checked the MAC to see if it matched with anything else i have in the house and its defs not mine.
 


In my case, the Blaze client was only the first of many different devices I've noticed, none of which are mine. It's weird because my own phones, that I know *are* on the network, don't show up. But all these others are popping up all the time. Never any IP address, never any information other than manufacturer, model number and MAC address. They disappear (usually) within minutes.

After some searching, I found Tom Tancredi's message here that seems relevant:
