We are using Windows XP Home Edition on one client and Windows XP Professional in another client. We are using a wireless DLink router for our network. Both clients can access the Internet, but they can’t ping each other. The clients have different names and the same workgroup. The router IP Address is 192.68.0.l and the clients are 192.168.0.101 and 192.168.0.102. Both clients can ping the router though.Why are the clients not pinging? Does anybody know what the cause of the problem is and how to fix it?
