    I'm going to add another IP Camera.

    The manufacturer's search tool shows the new (and exisiting) camera but indicates that my PC is not on the same subnet mask. After a quick "CMD--> ipconfig" search, I see that my wireless PC is on subnet mask while all other devices are on

    Keep in mind that I have ATT Uverse with a gateway that serves as a router. All other devices (wired or not) are on If I hard wire the PC to the router, I am assigned a subnet. If I unplug the Ethernet cable, the PC recognizes this lost network connection and goes to wireless where I'm assigned the subnet and therefore not able to connect with my ipcamera's, NAS drive, etc.

    While on wireless, Ive tried ipconfig /release and ipconfig /renew, nothing happens (still assigned

    I've confirmed in the in the network connections tab that TCP/IPv4 is setup to
    -Obtain an IP address automatically
    -Obtain DNS server address automatically

    I don't know what the problem could be. Im not sure why I'm being assigned a subnet outside of the normal What can I do?

    Perhaps your router has guest wifi enabled or some security setting isolating your device on the network.

    To what network are you connecting wirelessly? Apparently not the same one as all your other devices. If you can't answer that show for both the ethernet and wireless connection ...

    Open a (black) Command Prompt window:
    Hold the Windows logo key and press r; in the Run box type cmd and click on OK.

    Type the following command:


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

    [Press ENTER after each command.]

    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.
