Network Adapter missing - no internet connection

Sorry for the delay in replying, I've been working away.

So, I have tried a different cable and port. I assumed that the NIC had failed so bought a USB-LAN adapter. This installed fine but has made no difference at all. Now I have two network adapter showing in Device Manager but still no network hardware being detected by the OS. Any ideas?

Here is the ipconfig/all output, which is decidedly odd:
