Man, I gotta wake up!
What I am trying to say is:
Packet transfer happens at the layer 2 (OSI model).
Layer 2 is unaware of IP addresses.
The 802.11 protocol states that the association has to be done at the level
2 (MAC) which produces several IP addresses with the same MAC address behind
a a given AP.
That issue is resolved via ebtables and the 'fix' is named WDS (Wireless
Distribution System)
Clear as mud?

The first unknown ( .3 ) looks like a Canon device. Printer?
.8 is a Vizio device. TV?
.104 is a device from a company called Silex. Could be any number of devices.
They seem to make a wide range of interesting products.

I just used a MAC address search tool online.
The first one that came up for me was http://www.coffer.com .
The first part of a Mac hardware address is the manufacturer. The remainder is a unique serial number/identifier. The two together (are supposed) make a globally unique hardware address to prevent any possible addressing conflicts.
Some, er, less conscientious manufacturers aren't diligent about ensuring truly
unique mac addresses. It is easier and cheaper to make half a million exact
copies than the added cost and complexity of incrementing the MAC address.
MAC address cloning can cause issues also if we are not careful.
Hopefully that will help a bit in tracking what has connected to your network.
Let us know here on the list if you have any other questions or if we can elaborate.
Have a great night!
