Check that the first three numbers of your IP addresses are all the same.
Usually, in a home LAN, the first three numbers of the IP (192.168.1 or whatever) are the network portion. The network portion in a network must be the same so that computers can communicate. Otherwise, they're in a different network, and routers don't allow communication unless configured to do so.

PPOE is just for internet. Your lan is a separate issue. All workstations MUST belong to the same workgroup. Check your workgroup under start/control panel/system/computer name. Also it might be a firewall or sharing issue.
