Troubleshooting Chart

• 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 that its
length does not exceed the 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 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.
