Unknown devices connected to my router?

[Memoscorp]

Noticed my internet was a little slow so I checked out my router and found these devices were connected to it. My router tells me there are 9 devices connected: 4 ethernet, 5 wireless, but I can only recognize 5 (4 wireless, 1 ethernet) of them. Oddly enough, the computer I'm typing this on does not show up. Also, the ones I do recognize are DHCP while the unknown ones are static IP. Hopefully someone can help me out, cause it's making me uneasy. I'm no good when it comes to networking, so tell me if posting the IP and MAC address would help. I'm omitting them cause I'm paranoid about security (again, I know nothing about networking; sorry if it makes things harder).

The Microsoft ones are listed as media adapters rather than computers.

Microsoft Corporation - ”þðÔ”7Ä”¤¤
Connection type: Ethernet
IP Address:
IP Address Allocation: Static IP
MAC Address:
For some reason, this one is listed twice, both with the same IP and MAC addresses.

Microsoft Corporation - ”þðÔ”7Ä
Connection type: Ethernet
IP Address:
IP Address Allocation: Static IP
MAC Address:

15C39A000000
Connection type: Wireless
IP Address:
IP Address Allocation: Static IP
MAC Address:
This one is labeled as a computer, and gives me an option to "Access Device" (which points me to its IP), while no other entry does.

I'm using a Versalink 327W if that's relevant.

If there is any other information I can provide that will help, let me know. Thank you in advance.

Open up a command prompt (DOS box) on your computer and type ipconfig. That will show you all the IP addresses assigned to your computer.
