Cannot connect to computers on same subnet

ippingsubnet

Newbie question. I have a motorola surfboard router and two computers running windows 7 64bit Pro. Both can connect to the internet fine, but they cannot see each other. I need to remote desktop from one to another. The IP addresses assigned are 192.168.0.2, 192.168.0.3. The router has the IP of 192.168.0.1. I can ping the router IP from either machine but cannot ping the *.2 and *.3 from the other machine. It gives me "Destination Host Unreachable" error. What could be the issue.

Thanks,
Nathan

EDIT: Folks, I solved the issue. So the *.2 computer had an older 802.11g network card, while the *.3 computer had the newer 802.11n card. In the router, I had set the bandwidth to be 40Mhz so that the n-card could get 300Mbps connection. This however caused a problem while trying to reach *.2 from *.3 and vice-versa. I downgraded the bandwidth to 20Mhz and everything is working fine. However the n-card now has a connection of only 144Mbps. Not a show stopper right now.

Pinging in the same subnet does not require routing...

Looks like either (for a first start) 1) the Windows Firewall is blocking incoming connections (for the ping side & rdp) 2) Remote Desktop is not enabled (for the rdp itself) 3) If you are using Wireless - then the accesspoint might be configured not to allow client2client connections
