Help with Vista networking issue

I have a problem with my Vista x64 PC on my home network and hoping someone can assist.

The problem is I'm unable to connect to any other device on my network with the exception of my router.

When I ping a working local device (i.e other computer, print server, NAS) from my Vista PC I just get the destination host unreachable response.

My ipconfig /all results are shown below...

I have turned off Windows firewall, IPV6 but none of this has made any difference. Other computers on the network can ping and connect to the Vista PC but from the Vista PC I can't connect to anything other than the internet and my router configuration page.

Any ideas please?
