See Full map -- Abnormal map

[churin]

This is about networking between W7s in my home network. I have not been aware of any networking problem but I just checked network map by clicking on "See Full map" and the following is displayed. The same is displayed at the "B" computer except that the places for "B" and "GigaB-W7" are interchanged. Any idea?

From the layout of that diagram, it looks as if GIGAB-W7-2 is receiving internet from Unknown. Do you have a switch or something else between your computer and your router?

Where the "?" should be the name of your network through which you connect to the internet. What do you have between the computer and the router?

"GigaB-W7-2" is connected to the "D-Link System" router and to an ADSL modem: There is nothing between the PC and the router.
The computer "B" was originally connected to the Internet through other local network, but I wanted access to "B" from "GigaB-W7-2" so that I reconnected "B" to the network to which "GigaB-W7-2" was connected. I rebooted the "B" machine and the problem is gone.
Thank you everyone for your help.

Hello Churin,

Do you have your network adapter settings set like this below? It will not see the switch/modem/etc unless it is.

​

Hope this helps,
Shawn

Hi, Brink;

Yes it is checked.

Now, I need to report that what I implied in my previous post is not the cause of the problem.

There are three machines in this network. I was using "GigaB-W7" and other two(one of them is "B" as mentioned before) went asleep so they disappeared from the map. I waked them up then the problem came back.
Rebooting the two machines restores the normal map.
