Network Connection Problems
Cannot Ping the
Wireless Barricade
from the attached
LAN, or the Wireless
Barricade cannot
Ping any device on
the attached LAN
• 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.
Mobile users cannot
access the Wireless
Barricade
• Make sure that the Wireless
Barricade and all mobile users are
configured to use the same radio
channel, wireless domain (SSID),
and encryption keys.
• Ensure that all mobile users are
within range of the Wireless
Barricade as specified in
Appendix C.
