    'Limited connectivity' of course means that you don't have internet connection. Did you go to control panel...then 'internet connections' to see what it says? I would think that your ethernet connection is not set up right. Have you connected your laptop to the internet ever? I believe that your laptop internet connection device drivers are not installed, or have gotten corrupted. If you go to device manager and locate 'internet connection hardware' get to 'properties' and read the information.

    Many cable providers register the MAC address of the computer that is connected to the cable modem. Try restarting the modem after you have connected the other computer to force a re-registration. You can also set the MAC addresses on your laptop and desktop to be one and the same.

    Have you considered buying a router, so you can have internet access on both computers at the same time?

    No, a switch will not do.

    Did you try resetting the modem after disconnecting one computer and connecting the other?

    Yes, you can set up internet connection sharing on the desktop exactly like that.

    instead of a serial network
    which requires all systems to be active,
    get a router and let each system run independently
    modem---router -- systems A, B, C, D, ...​
    you will be mush happier with the results
