• Verify that the IP addresses are properly configured.
For most applications, you should use the Wireless
Barricade’s DHCP function to dynamically assign IP
addresses to clients on the LAN. However, if you
manually configure IP addresses on the LAN, verify
that the same network address (network component of
the IP address) and subnet mask are used for both the
Wireless Barricade and the LAN devices.
• Be sure the device you want to Ping (and the device
from which you are Pinging) have been configured for
TCP/IP.
