arp might have helped here, if you could have created some sort of
communication between your pc and the faulty router. If there was any
traffic on your network from the router, then its IP address would have
ended up in your Address Resolution Protocol (ARP) tables. /sbin/arp
would display these tables - the translation between the MAC address of
the router and the IP address it had been assigned/given itself. A
useful little program. Also, in situations like these, a non-switching
network hub and a pc/laptop running ethereal is also enormously helpful
- this allows you to look at all the packets transmitted on a given wire
on your network.
