This is sat two feet from the router...

Use a 2-foot ethernet cable

In reply to a post by micksharpe:

I don't understand why tracert is reporting a domain name (dsldevice.lan) for the router

It's a Thomson/Speedtouch router and that's what it calls itself. It's acting as a DNS relay for clients on the LAN and answers both forward and PTR requests. For its own LAN IP range it's authoritative for PTR requests.
