    Time to upgrade; WEP isn't very secure. You should move up to WPA, at the
    least. BTW, "WAP" means "Wireless Access Point"; which would be your
    192.168.1.200 and 192.168.1.205 devices. "WPA" means "Wi-Fi Protected
    Access", a security encryption scheme used on WAPs.

    Which, as Duane shows, does not prevent somebody from using any IP address
    outside of the range of your DHCP assigned IP address, but within the scope
    of your LAN IP addresses. Assuming your router at 192.168.1.1 is a Linksys
    router, and you have the factory default configuration, your DHCP range is
    192.168.1.100 to 192.168.1.150 (fifty devices), but your LAN scope is
    192.168.1.1 to 191.168.1.254 (IP address 192.168.1.1, subnet mask
    255.255.255.0). Any neighbor, or passerby, who can crack your WEP security
    (which is not terribly hard to do) can associate to your WLAN and assign
    themselves IP address within the scope of your LAN IP addresses. Using a
    MAC filter can mitigate that, somewhat. Using WPA security is much more
    certain.
