another subnet.
 

findsmb shows all IP with 10.255.240.X but also shows starting with 192.168.X.X

how this is possible for with out the router.

DISPLAYING IP ADDRESS BUT I CAN NOT CONNECT.

You probably can't reach this network because you don't have a "default" route where to send. These packets are probably coming from your own router, it is probably making the link between your network and the 192.168.X.X network... There is not really an easy way to make sure, you could install some applications to sniff packet or to listen to tram, but it would be hard work only to find out the source of a broadcast.
