Re: Unknown computers on local network - cable isp problem? ADKTech,
Do you have any other devices in your home that use wireless, like phones, game consoles, tvs, etc? They could be showing up in there. Although the names indicate they are actual PCs. Hmmm.
And an unrelated question, ADK, are you in the 'dacks? That's where I grew up. Right in the middle.

I notice in your screenshot you have your belkin as a media device in this Network and Sharing Center for the Win7 PC. I have no idea what is the primary use of your setup or what type of usb devices you have plugged into the PC in the past or currently..but I would start from scratch in Understanding the Network and Sharing Center for win7 and that might give you some clues why you are seeing Blacksmith.

Wow, Keene Valley. I used to spend my winters near there, going bobsledding. Would go to Purdy's in Keene for lunch every day. I was a member of the Hurricane Bobsled Club. |

said by ADKTech:What exactly is responsible for populating that network list? DNS? ARP? NetBIOS? I believe it's the browser service (this term was claimed before we had 'web browsers') and unless you have some device operating a WINS (Windows networking name service) server, it's operating by Netbios broadcasts.
On the other hand, I haven't kept up with the ever-more-complicated mechanisms that get added for network device discovery, and it's possible that the list is augmented by something like UPnP.
Try this experiment: open up a command prompt window and type net view. Is the list of computers the same as you see in the GUI? |

As best as I can tell, that was just the way the new Belkin N750 set itself up by default.
My understanding is that some new routers come with media capabilities, such as allowing you to share usb drives and printers, etc. I suspect this is just part of that.
In any event, I have no internet devices in the home that would take advantages of those services, or try to connect to them. No ps3, no xbox, no media streaming devices, or usb drives, etc. |

What about cable/sat TV DVR's, cell phone boosters like Sprint's airave, etc?

Ok, in an attempt to help us - and to avoid more complicated discussions related to network setup - I've broken this down to as simple a network as I can right now.
Cable modem > Belkin Router > 1 windows 7 laptop.
Last night I took all other computers off the network and they are powered down. There are no other internet connected devices in the home. We dont have an xbox or ps3 or media streaming device or anything else.
The Belkin's DHCP table shows only one client - the one remaining laptop.
Now, when I open up the network window on this last remaining laptop, I see 5 computers.
The 5 computers are: Itself, my desktop computer (which has been powered down for almost 18 hours now), something called "router", "grandmascompute", and "LanaHP".
That last one is new, it is not one I've seen there before... so new devices are still populating there somehow. |

Nope, nothing like that. |

If you ping those names in a Command window, do they resolve to an IP address? Do the IPs fall in the same subnet as yours? (are the first 3 numbers the same)

I am unable to ping or connect to them. |

I am unable to ping or connect to them. But does it say Host Not Found, or Request Timed Out? If RTO, it should show an IP address that you can compare to your public IP that your ISP provides to the cable modem.

If I try to ping the computer names it gives a "host could not be found" message for all of the 'rogue' entries...
EXCEPT for the 'router' entry, which resolves to my gateway (the Belkin router) |

kudos:9 | My best guess is that they're propagating from the internet somehow, but that shouldn't be the case if you have the firewall on your router enabled. What are the settings on your Belkin set to at the moment? |

Do you have an Ipod or use Bonjour ? Ever hook them up to that laptop or similar device.

OK, this is getting interesting - Wish I had a WIN7 machine to play with...
Have you used the PC(s) on any other network(s) by any chance? If so, WIN7 could have discovered them and kept them in the network list.
It seems you should be able to turn off discovery somewhere in the settings and should be able to delete those spurious connections on the page where you see them. (Right click, "delete", perhaps?)
Lastly, I'd call the ISP to regale them with the details of the things that are popping up, and see what they say.

If "router" resolves to the same IP as your belkin router, then you are now seeing 3 entries for it as shown in your image above? "Router" under the Computer section; Belkin N750DB Wireless Router: 1 under Media Devices; AND also the same under Network Infrastructure? That doesn't seem right.
Do you have anything else plugged into the router, like a USB media drive?
Do you have UPNP enabled in the router?
Do you have guest access enabled in the router?
If so, have you tried disconnecting and/or disabling these functions, and ALSO powering everything down (modem, router, remaining laptop from the outside in? (Meaning all OFF, then powering up each one at a time completely before proceeding to the next.. modem, then router, then laptop)

The screenshot in your OP appears to be the "add wireless device" screen. In that case, it may show past connections that it has discovered on other networks.
Go to the "Control Panel/All Control Panel items/Network and Sharing Center" screen and do a screen print. That screen should show your current and active connection(s).
See »www.addictivetips.com/windows-ti···ndows-7/ for the screen I mentioned as well as instructions on how to turn off network discovery in WIN7.

said by sk1939:The only thing I can think of is that a long time ago, most cable operators didn't operate with encryption over their networks. As a result, if you didn't have a router/firewall, it was one giant metro network with everyone in the neighborhood seeing everyone else.
Those were the good old days.
