After starting my Windows 8.1 laptop, if I go to the Control Panel\Network and Internet\View Network Computers and Devices, a device is listed that is not on my network.  It is listed as either a Ralink wireless client Model # RT286U or a full_ariel Model KFARWI and if I right click on the device and view the properties the Model #, Name, and MAC Address are shown. I checked the Device Manager and it was not listed in the Device Manager. Also, my router did not show it as an attached device. I have Win 8.1 laptop, a Win 7 laptop, an iphone, android phone, ipad, WD NAS, and HP wireless printer connected to a Netgear AC wireless router with MAC address filtering enabled. When I log into the router I have never seen either device mentioned above listed on the router list of attached devices nor do any of the devices I have on my network have the MAC address listed for either device.  After a short period of time the device disappears. I have set up my network as a private network.  My concerns are: Are the devices a security issue and can they access my network?  How come my computer detects them? The devices do not list either a work group or a network location so am I correct in assuming the devices are not connecting through my router? Is there anything I can do to prevent it from being detected?

Do you have a Kindle?  This (KFARWI) looks to be an Amazon Android device - of which the Kindle is the most common device (IMO).

Search Google for Amazon KFARWI

usasma:  Thanks for your reply.  No, I do not have a Kindle.  I also figured the device may be a Kindle, Amazon Fire tablet, or one of the other Amazon devices.  Unforturnately I do not have any of the Amazon devices.  I suspect perhaps one of my neighbors might but I have my router & computer in my basement so I hope there is good shielding from the neighbors.  What is puzzeling is the devices don't show up as attached to my router and also do not show am internet or workgroup connection.  I am surprised that they show up at all.  I have run several tests from GRC and also from the Technicians Toolbox and everything shows my computer and network to be secure.  Still I have this nagging doubt that I'm trying to resolve. I don't understand how the devices are being detected.

The device can show up if it's detected as a wireless connection.  I see this at work quite often where we have numerous different devices available to connect to.
This doesn't mean that it's connected to your device - rather that it's within range and that you can connect to it if you wish.

 

Try going as far away from your neighbor as you can and see if it's detected there.  If you have neighbors on both sides, go from one side of the house to the other in order to figure out where it's coming from.

 

You can see the same behavior if you take a wireless device out in public.  There'll be lot's of potential connections listed - you can even see this behavior on a phone or anything else that has wireless capability.

Thanks again for your reply.  It makes me feel a little more secure.  What is still disturbing though is that my computer picks up the devices' MAC. Does that indicate that there is some communication (request - answer) between my computer and the unknown device? Or does the unknown device, and all wireless devices, just broadcast its MAC to the world?

Depends upon the device and it's settings.

https://en.wikipedia.org/wiki/MAC_address

Scroll down to the section on Spying (the rest of it is pretty deep stuff).

I had checked out the Wikipedia site prior to my initial post.  I am trying to figure out if the device is making it through my Win 8.1 Firewall or my wireless adapter is just picking up its' transmission (my computer is acting like a radio receiver).  If the latter is the case then why do numerous networks (routers) in my area that show up when I click on the networks icon not show up as connected to my network also.  The fact that the MAC information (which I believe is OSI layer 2 information) is being received makes me wonder if the device could be using one of the tunnelling protocols to get through the firewall? I am running my Firewall with the default settings.

Way, way above my paygrade (an old military saying that means I don't have any knowledge about this)!

I'd suggest posting over in the Networking forum for more expert assistance:  http://www.bleepingcomputer.com/forums/f/21/networking/
