Troubleshooting Chart
Action
• Verify that the Wireless Barricade and attached
device are powered on.
• Be sure the cable is plugged into both the
Wireless Barricade and the corresponding
device.
• Verify that the proper cable type is used and its
length does not exceed specified limits.
• Be sure that the network interface on the
attached device is configured for the proper
communication speed and duplex mode.
• Check the adapter on the attached device and
cable connections for possible defects. Replace
any defective adapter or cable if necessary.
• Verify that IP addresses are properly configured.
For most applications, you should use the
Wireless Barricade's DHCP function to
dynamically assign IP addresses to any host on
the attached LAN. However, if you manually
configure any 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
attached LAN devices.
• Be sure the device you want to ping (or from
which you are pinging) has been configured for
TCP/IP.
