    You have the classic firmware problem. It's pretty easily fixed. Remove the device. Get a wired ethernet connection temporarily and do:
    Code:
    sudo mkdir /lib/firmware/RTL8192SU
    wget http://launchpadlibrarian.net/37387612/rtl8192sfw.bin.gz
    gunzip rtl8192sfw.bin.gz
    sudo mv rtl8192sfw.bin /lib/firmware/RTL8192SU/
    Reinsert the device and you should be working.

    I notice that ndiswrapper is still active and you'll probably have a more efficient system if, after you verify the native driver is working, do:
    Code:
    sudo apt-get remove --purge ndiswrap*
    sudo rm /etc/modprobe.d/blacklist
    Post back if you get stuck.

    Ok will do. Will have to move the PC upstairs for the router connection and do some tinkering then all should be OK i think

    Could i do this with another machine and then copy the files over with a usb stick?

    Certainly. Drag and drop the firmware file to your desktop and then:
    Code:
    sudo mkdir /lib/firmware/RTL8192SU
    cd Desktop
    gunzip rtl8192sfw.bin.gz
    sudo mv rtl8192sfw.bin /lib/firmware/RTL8192SU/
    Post back if you get stuck.
