Unknown device in computer/network

I have a toshiba laptop running Windows 7. There are 2 devices showing in Computer/Network, the laptop and something else with an alpha/num name appear. Can anyone tell me what the device other than the laptop might be and how to delete it? Thanks in advance!

Could you perhaps provide a screen shot and mark the device in questions with an arrow or circle it somehow.

Thanks for the quick reply. I don't have the ability to post a screen shot yet, but can tell you what I see. Clicking on "Computer" brings up the screen with "Favorites" "Libraries" "Computer" and "Network" in the left panel. Under "Network" is ZP_Laptop (which is my laptop) and AR53LPX7VYQ. I don't know what this device is and would like to delete it.

If you open the Network and Sharing Center, do you see it there, is it between your computer and the internet? Maybe a not so friendly name for your router.
