Have tried resetting router and box to no avail.

I run the network test and get the following results

LAN adapter - OK
Local - disconnected
DHCP - OK
IP address - unconfirmed
Nameserver - unconfirmed

I think it is something to do with the link I posted above, possibly about the box losing it's MAC address.

Any advice, help welcome. Box is over two years old now, so out of warranty
