Chapter 4 Troubleshooting

If you have trouble using the 11Mbps Wireless LAN Inter-Building Access Point, the starting point to troubleshoot the problem with your Inter-Building Access Point is looking at the LED activity of the Inter-Building Access Point. The following is “LED Error Table” provided to assist you in diagnosing and solving operational problems.

PWR	AP	WLAN	LAN	LINK	Description/Action
Continuous Green	Continuous Green	Flash Green	Flash Green	Steady Green	Normal operation where flickering indicates interface activity. No action required.
	Continuous Green	Flash Green	Flash Green	-
	On	Off	Off	-	Normal operation that indicates there is no LAN activity. No action required.
Off	Off	Off	Off	Off	Power failure. Check the power cord. Check the power supply.
Continuous Green	Off	Off	Off	Off	Invalid loader firmware or the Inter-Building-controller is dead. Return the unit to the vendor for support.
	Blink Green	-	-	-	Invalid Inter-Building Access Point firmware. Upgrade the firmware via the utility or console mode.
	Blink Green	Blink Green	-	-	Wireless LAN initialization failure Check whether the wireless module has been properly installed.
	Blink Green	-	Blink Green	-	Ethernet initialization failure Return the device to the vendor for support.

If you are still unable to solve the problem by checking the LED activity, the error may be caused from configuration mismatch, which prevents the Inter-Building Access Point from establishing a wireless connection with the network. You may check the following to ensure normal operation of the Inter-Building Access Point.

WEP keys: If data encryption is activated, always remember to set WEP keys exactly the same on the Inter-Building Access Point as are on the wireless stations.
Access Control: Make sure that the MAC address of your Inter-Building Access Point is not included in the Access Control table of other wireless devices.
