    Could you please open
    Device Manager
    Expand Network adapters
    Right click the problem WiFi adapter and choose properties.
    Select the Driver tab
    AND
    See if the option to "Roll Back Driver" is available"
    If so, perhaps rolling back the driver for your wireless adapter might provide some relief.

    As you can see from the results of you ipconfig.txt file, the OS is generating an APIPA (automatic private IP address) in the 169.254 range and that means that it is not receiving DHCP information from your phone which is (I presume) acting as your router in this instance.
    I just performed a test with my Windows Phone 8.1 and my wife's wireless windows 7 machine upstairs which worked perfectly. I've attached an image of my ip results along side of yours for your inspection.

    My guess is, that if this was working for you and has for some reason stopped working then perhaps Windows Update might have installed a driver for your wireless adapter that is less than optimal and rolling that back to the previous version might help.
    That's my best guess.
    You might also attempt to obtain the proper driver from your laptop manufacturer's website to see if that might help the problem.

    Yes I understand..... that you seem to have a number of cascading connections.
    Why not just use the same WiFi hotspot that you are using for your phone to support your laptop? Usually such devices support multiple connections at least five (5) or more.

    The basic problem is still the same.... No proper DHCP source that is providing the correct IP addressing including a default gateway and DNS server addresses.... No Internet Connection.

    I cannot speak for cellular hotspot devices globally as I only have some limited experience with the ones provided by Verizon.
    I know that they occasionally have software updates as well as firmware updates to support upgrades and changes in the provider's network.
    Have you had any communication with the device's provider? Have you checked on their forums to see if there is any other people having similar problems with your specific device?

    There is a small chance that some third party software / internet security suites / third party firewall products, network management software, various desktop sharing / collaboration software (LogMeIn, GoToAssist, etc.,) might be impacting your ability to get this working again, so.....
    If you've installed any of those lately, or had any of them update themselves to new versions then you might check there.

    I have only rudimentary skills as a technician and none what so ever as a magician. I cannot make something that I cannot see or touch work. I can only provide ideas and suggestions based on some clever and sometimes not so clever guessing.

    Your replies of "I've already done that" and "I've tried that already too" leads me to believe that I don't have any more tricks that you haven't "already tried".

    You haven't offended me or anyone as far as I can tell.
    What WiFi router do you have, Manufacturer name, model name, model number, firmware revision number?
    Have you tried changing the wifi channel on the router?
    Have you tried changing the security / encryption on the router?
    Have you tried running it open (no security) for a short test?
    Have you made sure that the router is in the proper mode b, g, n, ac) or a combination that your laptop's wireless card supports?
    Can you see the wireless SSID broadcast from the router?
    Are you prompted for a wifi key/password/pass phrase?

    Hence my confusion.
    Can we assume that you are using the term "Wi-Fi hotspot" synonymously with Wi-Fi Router (meaning Wireless Router)?
