The network number (192.168.0.0) is not the same as a host's IP number.
Also, this doesn't matter in a switched LAN situation.

This has sparked a memory: there is a setting labeled something resembling
"AP Isolation" that protects devices on the LAN from each other. It's
designed to be used in unsecured wireless situations, where you only want
guests to be able to reach the Internet, and not any of your local devices.
If you find this and turn it off, things should work better. On my Linksys
device, it's under Wireless -> Advanced Wireless Settings.

If the D-Link's range is 100-200, you want to set static devices like this
Linksys deal to something outside the range. Otherwise, the D-Link has no
way of knowing that some device already has the IP 192.168.0.103, and will
hand that IP to the next device that DHCP-requests one.
