    Pretty much all networking problems with your machine can be fixed by running the batch file below other than defining different subnets.

    From what I'm seeing here the router or it's settings are part of the problem, in that the subnet is different than the one at the school. When connecting to different subnets with the same adaptor you usually need to define or list the two different subnets and default gateways in the advanced TCP/ip properties window.

    The picture below should make it clear where you need to enter the two different subnets but you will need the subnet and default gateway from the school first.

    The batch file will be easier than running system restore and may be worth a try.

    This will will reset winsock, reset the TCP/IP stack and release renew your IP.

    Sorry, that doesnt work:

    C:\Users\user>ping ds410j
    Ping request could not find host ds410j. Please check the name and try again.

    All I can suggest is that you obtain the default gateway and subnet of the other network then define the two different different subnets and default gateways in the advanced TCP/ip window, use the "add" button.

    Doing that should allow you to switch between the two different networks without any problems.
