Connecting a Windows 7 laptop to another Windows machine via a Wifi Router and a Switch in a small office network


  • I work in a small office that has a Windows 7 PC that is being used as a Fileserver.

    Using my Mac laptop, I can connect to the Fileserver PC with no problems, but am unable to do so, using a Windows 7 laptop. The problem seems to be that the Fileserver is connected to the WiFi Router via a Switch.

    When I create a Network Map, I see this:

    My W7 Laptop   =  =  =  =  =   WiFi Router  ______________  Internet


    Fileserver       ___________     Switch

    Other PCs connected to the Network, show up at the bottom, in the list of devices that cannot be placed on the map.

    I have Admin privileges for all devices. How can I fix this problem?

  • Hi,

    We can try network troubleshooter tools and check if it helps.

    The built-in troubleshooting features of Windows 7 can help you resolve most matters quickly. However, you’ll occasionally encounter other issues that can’t be so quickly or easily resolved.

    Consider this: There’s a system that’s one of many running on a fairly complex small business network. The network has a single router and multiple network switches. When the OS starts, the computer is unable to connect to the network or to the Internet. The computer is running Windows 7 x64 and has a single 1.0Gbps network adapter.

  • Tao,

    Thanks for the suggestion, but it did not help.

    I can successfully ping the Fileserver PC from my Windows laptop and both machines have the same Gateway IP address.

    I also tried connecting the Fileserver PC directly  to the WiFi Router, rather than through a Switch but that did not help.

  • Thanks for asking, but sorry, no good news.

    I can ping the Fileserver (Ethernet link to Router) from my W7 laptop (WiFi link to Router) and vice-versa. However, I cannot connect to them in Windows.

    In particular, the Fileserver Network Map shows my W7 laptop in the list of devices at the bottom of the map, labelled:

    "The following discovered devices(s) can not be placed in the map."

    My W7 laptop Network Map shows a "? Unknown" connection to the Router.

    My Router is an Asus RT-N66R WiFi Dual Band device.

    As I mentioned before, my Mac laptop has no problem connecting to the Fileserver.

  • Do you have a successful connection APPLE PC ----> ROUTER----> FILESERVER

    but an unsuccessful connection WINDOWS PC----> ROUTER----> FILESERVER?

    The switch was removed so that eliminated the hardware as a source of the problem.

    And more than one windows PC has been tried?

    And was the router reset or rebooted?

    Perhaps this issue can be troubleshooted with ASUS:

    Please let us know about any progress.
