    I have two Windows 7 computers and one XP machine on a wireless network. Two machines can see the others but one running Windows 7 can't see the other two. While trying to find out why, I noticed that whenever trying to view the network status on the problem machine, it knocks out the internet for everything. The computer that is causing trouble is wired directly to the router. Help?

    Please show the following for the XP and for the problem PC, both when they have internet access and for when internet access has been lost.

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    Let's expand that to include some diagnostic pings. When the problem computer does not have Internet, please do this.




    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

    NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work. Also, the < and > in the text is to identify the parameters, they are also NOT used in the actual commands.

    Do NOT include the <> either, they're just to identify the values for substitution.

    IPCONFIG /ALL

    PING <computer_IP_address>

    PING <default_gateway_address>

    PING <dns_servers>

    PING 74.125.45.100

    PING yahoo.com

    Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
    Paste the results in a message here.

    <computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above. (For Vista/Win7, the IPv4 Address)

    <default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

    <dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.


    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    That's very strange! Please also tell us precisely what is meant by "trying to view the network status on the problem machine." Exactly what commands or clicks or whatever.

    So of course even when it's not working it's inconsistent. I noticed the ipconfig result was different than the one before so I got all the addresses to ping from the previous one.

    Exactly what seems to be happening is when I go into "Network" from the start menu to see and be able to access the other computers, the network window opens and for about 10 seconds or so I can see all the computers' icons. Then they and the router icon disappear and internet access goes down intermittently for about a minute. Eventually the icons for the router and the computer itself come back and I can access the internet but the other computers on the network don't show up again.

    On the Windows 7 machines: Network and Sharing Center - Choose homegroup and sharing options - Change advanced sharing options - Home or Work - Choose media streaming options... - if it's set to 'Allowed' try "Block All" and see if that makes a difference.

    Nope sorry, I changed it to block all and it made no difference.

    Well I feel dumb now. I finally got it working when I realized the problem was the router. When upgrading to Windows 7, I never gave it a thought as it was supposedly compatible. Upon closer inspection I noticed the firmware was not up to date. Updating the firmware fixed the internet connection problem, and after fiddling around a bit more I think that disabling the homegroup on the Windows 7 machines finally allowed me to see all computers on the network.

    Homegroups are a Windows 7 only feature, so that makes sense. :)
