When I attempt to use the
See Full Map function in Windows 7
Control Panel\Network and Internet\Network and Sharing Center it always abends.
I really have no idea what the problem may be. I am sure this Windows network topology map function worked when I was using the Win 7 pre-release. However, now that I am using the retail RTM version of Windows 7 Home Premium (64-bit) I can no longer create a Network Map. My best guess from the (so-called) "help" provided is that a "device" (my router?) is incompatible with Microsoft's Link Layer Topology Discovery (LLTD) protocol.
Below is a text diagram of my LAN. The error occurs even when the only system connected to the DIR-655 is my Win 7 desktop. This is why I suspect the DIR-655. But what could be wrong??
If a setting in my router is preventing LLTD from working I have no idea which it might be. Was hoping I might get a suggestion on what to start looking at.
Type of Connection  coax ( Internet ) | wired ethernet ( ISP ) : wireless ethernet  [Motorola SB5100 "Surfboard" cable modem] | WAN ===================================================== + D-Link DIR-655 router, firmware v1.34NA, 2010/04/16 + ===================================================== | LAN | : | | Wi-Fi | | : [Win 7 64-bit] [Seagate Dockstar] [MacBook OS X 10.6.4]
I've tried resetting the DIR-655 to factory defaults, rebooting Windows, then trying to map my network. It failed in the same way. But at least now I have some confidence the problem is not a result of anything (obvious) which I did to the configuration.
For what's it's worth, this function works again. I do no know when it started working again. I do not know why it is working. But it is working now.
Is there a way to close a question as "No longer any point in pursuing?"
