Description:

This article describes the meaning of LED blinking characteristics of LANCOM routers and access points.

If all LEDs glow red permanently, there are two possible causes:

  • The LEDs were set to red via the LED test (Setup/Config/LED-Test). The LEDs can be set to red, green and orange and can also be deactivated via the LED test. In this case the device works normally. 
  • The reset button is jammed. In this case the device is in a reset loop and doesn't function normally.


1) LANCOM router:

Routers in CPE case (all routers except IAP-4G+, IAP-1781VAW, 190x Serie and Central Site Gateways) feature two additional LEDs on the top side:

  • Left LED: Power
  • Right LED: Online


1.1) VPN router:

LED blinking characteristics of the power LED:

  • 1 x green inverse blinking: The LMC is reachable but there is an issue within the LMC (theoretical problem which should never arise)
  • 2 x green inverse blinking: Pairing error or activation code doesn't exist
  • 3 x green inverse blinking: LMC not reachable or communication error

2. LANCOM Access Points:

2.1 Indoor Access Points:

L-321agn

WLAN LED blinking red: Hardware error in the Wi-Fi module


There are two additional LEDs on the top side of the device: 

  • Left LED: Power
  • Right LED: WLAN Link


LED blinking characteristics of the Power LED on the top side:

  • orange / green blinking alternately with the WLAN Link LED: The access point is searching for a WLAN Controller (default setting of the Wi-Fi module "Managed")
  • orange / red blinking alternately with the WLAN Link LED: The access point is managed by a WLAN Controller but the WLAN profile cannot be obtained because the Firmware and/or Loader version of the access points aren't compatible with the WLAN Controller 
  • 1 x green inverse blinking: The LMC is reachable but there is an issue within the LMC (theoretical problem which should never arise)
  • 2 x green inverse blinking: Pairing error or activation code doesn't exist
  • 3 x green inverse blinking: LMC not reachable or communication error

LED blinking characteristics of the WLAN Link LED on the top side in mode "Managed" and "Access point":

  • Glowing green permanently: Wi-Fi module active
  • 1 x blinking green: A Wi-Fi device has connected (good signal quality)
  • Blinking green multiple times: Counts the number of connected Wi-Fi devices (default setting)

LED blinking characteristics of the WLAN-Link LED on the top side in the mode "Station":

  • Blinking green slowly : Good signal quality to base station
  • Blinking green fast: Bad signal quality to base station
