Wireless Problems
A wireless PC 
cannot associate 
with the 
Barricade.
• Make sure the wireless PC has the same SSID settings 
as the Barricade. See “Channel and SSID” on page 25.
• You need to have the same security settings on the 
clients and the Barricade. See “Security” on page 27.
The wireless 
network is often 
interrupted.
• Move your wireless PC closer to the Barricade to find 
a better signal. If the signal is still weak, change the 
angle of the antenna.
• There may be interference, possibly caused by 
microwave ovens or wireless phones. Change the 
location of the possible sources of interference or 
change the location of the Barricade.
• Change the wireless channel on the Barricade. See 
“Channel and SSID” on page 25.
• Check that the antenna, connectors, and cabling are 
firmly connected.
The Barricade 
cannot be 
detected by a 
wireless client.
• The distance between the Barricade and wireless PC is 
too great.
• Make sure the wireless PC has the same SSID and 
security settings as the Barricade. See “Channel and 
SSID” on page 25 and “Security” on page 27.
