    Opening CMD, I try ipconfig/all & a strange IP address of appears.
    This confuses me to no extent.
    ipconfig?renew does not solve the problem.
    Bringing the Dell laptop to a friends house it connects immediately to his network with his IP address.
    Coming home - same unknown IP address appears.
    Restarting router does not help (but the two other computers connects fine).
    My Dell wireless adapter TCP/IP properties is set up to "obtain IP address automatically".

    I tried to "use the following IP address" and tried as IP address & as Default gateway. It connects nicely with the Router, but no internet connectivity.

    When connecting the Dell to the router via a cable, it works beautifully & connects to the net.
