The following table provides LED troubleshooting suggestions. 
 

 LED does not turn On. 

Check power connector is properly inserted. 

 LED turns Red. 

Remove power and re-apply. If the Power LED 
remains Red, contact Quatech, Inc. 

LED is Amber. 

Bridge has not established an IP address either 
through DHCP or Static methods. 
DHCP is the default method by which the unit 
obtains an IP address. Your network must have a 
DHCP server available when the bridge is powered-
up. Most AP/Routers have a DHCP server built-in. 

Enable your DHCP server and re-start the module. 

 LED continues to Blink Red. 

Bridge has not found an Access Point with which to 
associate. Be sure the Access Point you want to 
use is turned on and has WEP disabled (you can 
enable WEP after the Bridge has been configured). 
If this does not help, be sure there are no nearby 
devices causing interference. If there are, either turn 
off or move the device causing the interference or 
move the Bridge and Access Point to another 
location. 

 LED is Off or Amber. 

Be sure an Ethernet device is connected to the 
Bridge and that the device is turned on. 

 LED is Red and Link LED is 

 but you are unable to pass data. 

No open TCP socket is recognized by the Bridge. 
Be sure you have an open TCP connection to the 
bridge and the connection is in data pass mode.
