Can you try booting a GNU/Linux live image on your laptop? Any distro will do, really. Just put the live image onto an empty (or emptiable, i.e., with no important data on it) USB stick and boot it. If the distro recognizes the Ethernet port, you will know that it is a driver issue and that you need to find a Windows driver for the device if you want it to work under Windows. If it also does not work in GNU/Linux, then it is likely a hardware incompatibility.
